Brownie's 2.0 - What a sssslllluuugggg
« on: December 15, 2011, 11:43:31 PM »
NOTICE: This thread is partially linked to the following thread to help diagnose these issues:

http://www.fordpinto.com/parts-resources-here-is-where-you-can-find-this-or-that/where-to-get-2-0l-piston-rings/msg121047/#msg121047




So Brownie has been on the road for about a year now. She has had her ups and downs, lots of TLC and gone through the first transmission with bad clutches, a second transmission which went out due to crud in the cooler and torque converter, and now her original transmission is rebuilt and going strong!

Before getting her road worthy she got a valve adjustment and the valve cover gasket replaced. Points put back on and the old crane cam electronic ignition removed due to a bad shutter wheel (may be repaired soon).


Now that I drive her twice a week, I am noticing some performance things and eliminating possibilities contributing to her sluggish performance.

Here are some symptoms:

1) Very slow acceleration. She is slow to accelerating 80% of the time, usually when trying to accelerate after braking and not coming to a complete stop. However, when accelerating from a dead stop she accelerates decently.

2) Upon cold start, the engine acts like the choke is doing it's job until about 20-30 seconds after start-up it starts to "mis-fire" or sputter until I step on the pedal. Then it sputters a bit, then smooths out and idles smoothly.

3) When climbing even a slight hill/inclined road, it starts to smoke greyish white clouds. Not a little puff, but billows of smoke if I stay on the gas. After I get up the hill or incline it lessens, but after it starts to smoke it really never stops.

4) After driving for an hour and a half or so and coming to a complete stop, then going again, it starts to smoke almost all of the time. Not badly, but enough to make anything in the rear view seem hazy. With this comes even slower acceleration than before, and giving it any extra pressure to the throttle makes no difference, only more smoke.

5) The carb has been rebuilt twice, and I am not really suspecting it, but the tune of it probably has some part in the rich smell at times.



I am leaning towards a bad head gasket, and what aids in that assumption is that I checked the coolant level today for the first time since I parked her after my Sunday drive (when I noticed the smoke for the first time in awhile), and the coolant level HAS dropped about an inch, just barely covering the fins at the top of the inside of the radiator. The water pump and thermostat do not leak, and I replaced both gaskets before getting her running again.

If it is the head gasket, I have a few questions:

1) Is it normal for a motor that has been sitting a long time, but with low-ish mileage (91k true miles on the odometer), to develop head gasket issues?

2) I have run a few compression tests and they are giving results around 130-135 per cylinder. I cannot remember if any neighboring cylinders are lower than others though, need to do another test.

3) I would like to recondition the top end just to ensure it is done, but how can I get the valve springs closest to the cam towers to compress? The only compressor places have for sale or for rent around here are the fork type that push down on the spring with the fork fingers and against the valve stem.


A head set isn't to expensive ($39.99 before tax), and I am certain it needs new valve stem seals at the very least.



Is there something else that could be contributing to these issues that I am overlooking, or am I on the right track with the head gasket? Coolant loss is my biggest clue, but i don't smell coolant in the exhaust, however when it idles on my parents driveway it can leave a black mark on the driveway at the exhaust pipe with an oily patch in the middle. Lots of what I call "soot" though.

Hey Dave, do the compression test again and if all cyls are close you should be fine on the head gasket. Also check the oil for antifreeze. You radiator fluid level sounds fine to me, just covering the fins is where is should be.

my thought on the smoke and accel issues however may have root in this... I have been told there is a vaccum line from carb to auto trans with a valve involved in the system. If the valve is failing tranny fluid will get sucked into the carb and burned thru the combustion process and can cause smoke out the tailpipe. I'll admit I don't know much about this but believe the way to test for that is to remove the vaccum line at the tranny and if you see trans fluid leaking... that may be the problem.

Dave (flash041) is the one that told me about the trans issue and may be able to tell you more
http://www.fordpinto.com/profile/?u=7334
 
also... if you are not coming to a complete stop and accel is sluggish I wonder... is it not shifting down into 1st gear? and you are starting in 2nd? and when you come to a complete stop it does get back into 1st? also may be a clue to the above listed issue? maybe?

the choke/carb issue at startup just sounds like a choke setting or carb settings to me anyhow. With it running rich as you described it would leave soot out the tailpipe that can mark the pavement as you described, unburned fuel?

then there is the head and valve seats... they could also cause your smoke out the tailpipe. Since your car sat for some time before you got it and yes, at 90K+ a head rebuild may be in order.

as a "non-mechanic" and no expert on all mechanical issues by any measure thoes are some of my thoughts anyhow
It's all about the Pintos! Baby!

Dave, after chasing the smoking issue on 2 of my 2000cc Pinto's, I'm going to say it's valve stem seals causing your smoking issues. I have a valve spring compressor you can use, it works on the 2000cc head, I'd also make sure you get a Fel-Pro head gasket, you said it has 90K miles, it will need cam bearings, and might need guides, both should atleast be checked.
Let me see what I can come up with, I have 6 cylinder heads, only 1 is stock, I'll look at the stock one, if the guides are ok, I have a set of new cam bearings, maybe we can put a head together for you, or freshen yours up.. You know where I live, and you have my number, if you want some help let me know.....

the part cookieboy is talking about is the vacum module
i just changed it on  my maverick. mine was going through a quart of trans fluid in a week burning some and the rest ended in the oil pan.

I think your pinto n mine are twins separated at assembly in the fremont plant down in the SF bay area. I too am having smoke issues-checked the plugs n they look new-almost like I'm running too hot? Mine has 91k and was thinking about a top-end rebuild. I have slowly been fixing things here n there, this week repaired/replaced driver's side door hinge pins n bushings. Front calipers weren't fully engaging so gave them a taps with a BFH and cleaned surface rust at friction points. I'll definetly check the vac line from tranny! Mine especially when its cold like now in the 20's n 30's after warm up I put it in drive n nothing happens? I have to cycle the shifter back to park then down each selection then back up to drive before it goes? Have you experienced this?

Walt I think you are on the right track. Hopefully with the head pulled it will be a no brainer as to what is going on.

Brain: I was thinking that to, but I have gone through three modulators on this (once replaced on this transmission before the rebuild, one on the spare transmission, and now another new on the current rebuild). I have never seen any transmission fluid in the line though, at either end.

I have been planning to swap out the water choke for an electric one, identical to my 78's, for ease of troubleshootin g and a sure fire unit that I know and have experience with, just haven't found the time to do the swap.

Dave, it sounds like your transmission has what is commonly called "transmission morning sickness". Brownie did it on the current transmission before the rebuild and shortly have the low mileage spare was installed. While it is still drivable, it won't be for much longer. The symptoms are identical to a transmission low on fluid.

What is going on is your clutches are worn/burned/glazed, and your seals are bad (most likely dry and hard) to the point where they no longer are a friction surface. In Brownie's case, the clutches were worn, and the steel plates were glazed), also the seals in the clutch packs were hard as ABS plastic and broke into pieces during removal. I used a Pioneer kit to rebuild my C4, and it wasn't hard to do at all, just time consuming. In fact, it came with an extra set of clutches which I am putting into the spare C4 transmission I have at my parent's garage before I move it to my storage unit.

Here is the link to my C4 rebuild thread. I have PM'd you the link as well.

I think that your thread on the rebuilding of your trans was / is one of the best I have ever read.  It really got to the point and was very easy to read and understand.

Weird, I just got done with some tests and here's the results:
 
 Compression test yeilded these:
 
 Cyl 1 - 130 PSI
 Cyl 2 - 130 PSI
 Cyl 3 - 130 PSI
 Cyl 4 - 130 PSI
 
 All the same across the board. Engine cranked for six seconds for each cylinder, pressure climbed evenly and the same for all cylinders.
 
 
 Plug check:
 
 Cyl 1 - Normal, tan colored, no damage or deposits
 Cyl 2 - Normal, tan colored, no damage or deposits
 Cyl 3 - Dark brown, Light carbon deposits, no damage though
 Cyl 4 - Normal, tan colored, no damage or deposits
 
 No oil on the threads, no oil anywhere other than that.
 
 
 Pressurized the cylinders up to 100 PSI:
 
 I cannot remember the exact results, but at less than 60 PSI there I was getting pressure in the valve cover. I could hold my hand over the oil cap hole for five seconds and release it. Built up air would escape after removing my hand.
 
 I remember that on two cylinders (specificly three and four) it seems the valves are damaged or not closing completely (may need another valve adjustment), as I kept getting a steady small amount of air out the tailpipe.
 
 I didn't ever get any bubbles in the radiator though. Odd, because I have coolant leaking from SOMEWHERE. I popped the cap off before doing anything and there wasn't even enough coolant to cover the tops of the fins. I had to top it off with 1/3 of a gallon of coolant.
 
 
 
 Coolant loss concerns me, since I rarely drive the car, maybe three or four times a month in the past three months, and even then, 3/4 of the times it is only down the road 1/4 mile to work, and back. Not even long enough for the engine to warm up completely.
 
 I stopped driving it so much because of the smoking under heavy acceleration or hill climbing issue. I was originally thinking coolant leaking into the cylinders due to a bad head gasket or something.
 
 I suppose things will become clearer once the head is off.

Those compression readings sound good but one question.. Was it a wet or dry test? Also it does sound like either you have a bad valve or valves out of adjustment. 90k on that year of a car could be considered rather high miles. my 77 needed all the bearings replaced at about 115k miles. It also depends how the previous owner took care of the car. The best thing to do is prolly tear down & rebuild the engine so you know it's good & solid.

Sorry, I supposed I should have mentioned that, lol.

The compression test was a dry test. I saw no reason to perform a wet test after getting good compression readings in each cylinder while dry.

From what I can gather and what little paperwork I still have from the original owner, it was quite well taken care of before it was parked, and then the original owner passing away. There are some receipts from a couple different Ford dealerships that did oil changes and a valve adjustment from a shop about two years before the car was parked.

When I pull the head I will be able to see how bad the valves and seats are. I have a spare head rebuilt and adjusted to put on after I inspect it all. Hopefully next Wednesday I can get it done, should nothing unexpected come up. (knock on wood)

Lol yeah, I'd say that's really good compression for a dry test. Sounds like that engine was really taken care of. Hopefully it isn't too bad. Gotta love cars. If it ain't one thing, it's another.

Working on them is one of the most enjoyable things, I think. Doing it yourself, and then driving it and enjoying something you put together with your bare hands is one of the most satisfying things one can do!

Those numbers look real good on the compression test. The way you described the plugs I would almost bet your problem is going to be valve stem seals.

Thanks RSM, that's motivating! I'm still going to pull the head and change the head gasket since I have a good spare head already freshened up and ready to go. If there is a lot of carbon build up on the pistons, is it save to wire wheel it off?


One question I just tossed around in my head...

How much slower should this 2.0 w/C4 auto be compared to my 2.3l w/4spd manual when it comes to acceleration?

Even when I had the 2.73 geared axle in my 78 it accelerated faster than this 2.0-auto does, and it has the 3.41 gears!

Well I started to disassemble the motor today, only found one concerning thing, which is the vertical score line on the number one cylinder against the exhaust side of the cylinder wall. It isn't to deep, and I believe honing will remove it, it isn't quite deep enough to catch a fingernail on. Other than that the cylinders look pretty good. They even still have the has marks from the original honing!

The head gasket was not compromised, however I can tell the valve stem seals were leaking due to the heavy carbon deposits on the tops of the valves.

The head actually appears to be in great shape. The valves haven't recessed any from what I can tell. I haven't yet pulled it apart to check the stems or the seats yet though. The exhaust valves have A LOT of white deposits on the cylinder side, which I have never seen before, going to research that.

As for dismantling the engine, I finally got around to pulling the AC compressor, which will not be going back on, and the brackets for it as well. I managed to remove the manifolds, head, alternator, auxilary pump sprocket, seal cover, and the crank pulley. I cannot get the front crank cover to come off due to the timing belt sprocket being stuck to the crank shaft.

I wire wheeled the carbon deposits off the piston crowns and remains of the head gasket material from the deck. Carbon deposits wern't bad on any of the piston crowns, but only slightly heavier on the number 4 piston, but nothing difficult to remove.



Here are some pictures:

Any ideas how to get that stuck timing belt sprocket off the crank shaft?

Next up is to pull the pan and pump, clean out the crank case and pound the oil pan back into something that LOOKS like an oil pan! :P


Here are pictures of the cylinders. First is cylinder 1, second is cylinder 2, etc...

Also, no ridges on the tops of any of the cylinders, which is good. I won't have to bust out the ridge reamer! :D

Got the gear off today! I ended up drilling holes on opposite sides of the sprocket and tapped them for 1/4" x 28 bolts. I used my gear puller on it, with the aid of the impact wrench since the wrench wasn't enough. Even with the impact wrench, it took about five minutes constantly running to get the sprocket off! However, I do have it off and it is still in one piece! Once that was removed the crank seal housing cover came off without a problem!

Since I didn't want to pull the transmission to raise the motor, I dropped the steering rack, which allowed more than enough clearance to drop the oil pan and the pump pickup.

After the pan was down, I was able to see the cross member, or what was visible of it under all of the 1" thick caked on dirt and oil build up from the past 37 years. It's better now that I have cleaned it with a scraper/putty knife, but not perfect. At least I can see where the metal folds and the curves of the cross member are!

Once that was cleaned up and I wasn't afraid of turning black from touching it all, I pushed the pistons out the top of the motor, cleaned them up and put new rings on them.

I honed out each cylinder with the motor in the car, and cheese cloth at the bottom of each cylinder to catch any particles from the honing process, which really isn't to bad once you have the hood nearly vertical and can stand on the frame while using the hone from above.

Once the pistons, bearings and crank were all lubed up with assembly lube, the pistons were reinstalled and the rod caps were torqued down to 33 ft/lbs, and the motor turned over well without any seizing.


Hopefully tomorrow I can clean up and "re-form" the oil pan, paint it, clean off the mating surface on the block, and put the pan back on. Once that's done the rack will get new bellows and mounted back on. From there it's just a matter of putting the rebuilt head on the block and then everything else should be a breeze!



One question, what should I toque the head bolts down to? I am reusing the original ones, from what I have researched they can be used twice.

Here are some pictures I shot today.
 
 1) Crank timing sprocket. Two holes drilled for bolt puller.
 
 2) Front of crank shaft, not much rust, odd that the sprocket was so stuck!
 
 3) Pistons. 4 - 1, left to right
 
 4) Oil pan with black oil in it. You can see some of the dents in the sump.

Dave ,
First beg borrow or buy a "Bottoming tap " of the same size as the head bolts. This will allow thorough cleaning of the threads in Block, and you will not be tightening against corrosion or debris.  Since the 2.0 doesn't use  torque to yield bolts, you can reuse once. My chilton's 71-72 book shows a Torque procedure in three steps: first to 14-29 ft lbs, second 36-50 ftlbs, third 65-80 ft lbs . Starting in the center bolts, and moving outward in a cris- cross pattern to the outside of the head. There is no mention of any thread treatment like Never seize, and that means only lightly oiled threads on the bolts. Dont forget, Cam goes in before head goes on! Have fun..

Just thought about this, do I need to re-torque the head bolts after 500 miles?

Yes- re torqued my 2000 to 95 lbs after 1000 miles. Can't remember where I read this- what do you say Joe?

Scott,
 The issue of retorquing head still may apply to the Iron head to Iron Block, But I 've heard people say it's not necessary with the better quality FelPro head gaskets. That retorque procedure was relevant for Hi- Compression motors in the past. Not sure about that with the newer gasket designs. Even O- ringing the blocks is for hi- boost or Very High compression racing motors these days.
Consult the Head gasket Mfr to be sure ..

Been busy cleaning parts and what not. Got the thermostat housing, crank timing cover, aux-shaft cover, pan, belt cover, intake, valve cover, and bolts and stuff cleaned/painted (the blue parts).

I started cleaning the head tonight, I think I may keep the original one as it looks like the valve seats are in great shape so far, though I haven't removed any valves yet, still cleaning carbon out of the chambers. Once that's done I'll pull the valves, clean them up, and lap the valves and seats if they are good.

Need to buy more wire wheels and cleaner, and another set of valve stem seals.

I bought a plug tap from Fastenal for $16, and a die to use on the bolts for $6. For reference, the bolt and hole sizes are M12 x 1.75. I used a ratcheting tap handle to chase the threads in the block, which made a huge difference. I picked up the die, which was special order, today and will chase the bolt threads on Sunday.

1) Top on the ratcheting handle

2) Difference between dirty threads and chased threads.

Question....

I am using assembly lube on all the bearings, on the pistons, and will be using it on the cam lobes as well.

What type of oil should I use for the initial run and break in? I was using 20w 50 before the build, but should I use a normal 10w40 for the first 500 miles and then change back to the 20w 50?

I just don't want to starve the motor of proper lubrication after a refreshening
