1978 Pinto Squire - 2.8 Cologne Vacuum Diagram?
« on: March 25, 2017, 07:25:09 PM »
Greeting Everyone,

I recently picked up a 1978 green Pinto Squire Wagon w/ green plaid interior off of a friend of mine.  He's had it for a couple of years and it's been a good runner so when he decided to move on from it I took it to use as a beach cruiser. 

One of the reasons he was selling it is b/c he was having trouble with the idle and couldn't figure out what the issue was.  When twisting the distributor stopped working he decided to take apart the carb, give it a good cleaning and then "simplify" it by removing all the vacuum lines. Said this worked on his old Dodge pickup so it outta work here. 

As you might guess, it didn't come out so well. The car idles very low right now so you have to keep your foot slightly on the gas to keep it from stalling.  Kind of a pain since it's an automatic trans.  I've been scouring the internet trying to find a diagram of the vacuum lines to so I can return it to a stock setup and then troubleshoot from there but I can't seem to find anything.  If anyone can point me in the right direction this will be a good start to solving my problem.

Thank you kindly.  Looking fwd to hanging out here as I get this baby back on the road.

One do you still have all the smog crap on the car , if you do not it will be a easy one to do , the egr valve is known to stick and cause an idle problem , blank if off to make sure , next is the smog pump , by now most of those are toast , just remove it all to make room under the hood, so that leaves only a few vacuum lines , If you have A/C one line goes to the vacuum can in the right fender to the vacuum tee on the engine , along with a line to the power brakes if you have them , the last one is the distributor , pull the cap off mane make sure the springs inside are not broke and the mech advance is working , install cap back on and set timing to 10 deg , the last line from the dist also goes to the vacuum tee , the engine will speed up when you do, if you stil have idle problems ask if the cam gear set was ever changed , if it has the bolt the holds the cam gear has become lose and the gear will work back and forth giving timing issues , hope this helps later Blaine

Thanks for the quick response Blaine.  Attached are pictures of my carb from different angles so you can see all sides of it.  To be honest, I'm not quite sure what I'm looking at.  I think all the smog stuff is gone and it definitely does not have A/C.  Pretty sure there's no power brakes since they are operating just fine as is. 

Checked the distributor and it looks good.  Timing is correct as well.  Cam gear was never changed so I don't believe that's the issue.

Can you elaborate on "the last line from the dist also goes to the vacuum tee , the engine will speed up when you do,".  If you see anything in the pics that will help me let me know.

Thanks a lot.  Looking fwd to getting this thing running sweetly for summer.

Passenger side view of the carb (pic was too big to attach for some reason).

Wow , you sure have a lot of things missing , you choke system is gone and the screws are stripped out that holds it , your kick down for the transmission is unhooked , (missing clip ) and the anti diesel solenoid is missing , that kind of explained the low idle , but you can turn the idle screw in a few turns that will help some , looks like it's past due for a good cleaning and bet way past due for a valve adjustment , (yes this engine does not have hydrolic lifters ) you suppose to do it every 15K miles , the vacuum lines are hard to see where they are hooked to , but some TLC will wake it up , do not know how much you want to spend on it but you need a carb for it to run right , the egr valve is still there , and you PCV valve is not hooked up eather, but fixable with some time , to bad you don't live near here so I could help you , did the guy you got the car from give a box of parts he took off the car and could not figure out where they went ? ?   I will look and see if I can find a vacuum diagram for you ,

I question your thoughts on power brakes.  Picture 1 shows a rubber hose in the upper right corner behind the wire loom that might go to the brake vacuum canister.  The brake master cylinder is bolted to the canister, which, is bolted to the firewall.  Picture 4 shows a large rubber hose going around the back of the distributor to the left side of the car. In the background on the middle left of the photo the shiny black thing looks to be a vacuum canister. Brake master cylinders are cast and are not black. At least I haven't seen one that was painted. That line seems to be the vacuum line for the power brake canister.  I only say this because most V6 cars had power brakes.

I also noticed many blocking caps in the photos.  All caps and hoses that are loose, oil soaked or cracked should be replaced. Until you stop all vacuum leaks you will be chasing your tail trying to settle your idle. After that , you will start to find the mechanical problems.

Have fun and good luck. Keep us posted on your progress.

Have to look at my other place for my books on the vacuum line diagrams , also do you you have the air cleaner , they are vacuum lines that go to it also , on the side and bottom , like to hear what you have left to make it simple and not the snakes nest like it was before , and where are you located . I am in Mississippi along the coast , later Blaine

Ok so I had some time to tinker w/ the Pinto this past weekend.  Turned the idle screw a few turns which did help it idle better.  Sadly I couldn't get it started again to keep messing w/ the screw b/c I think maybe the ring gear is stripped.  Check out the following video I took. 



Sounds like the starter is going so perhaps the ring gear is stripped?  Car does eventually start towards the end of the video.  Foot needs to stay on the gas to keep it from idling too low and stalling out.  I got out, ran to adjust the idle screw some more but it stalled before I could get there.  Couldn't get her to crank over again after that.

Also, attached are some photos of random vacuum related parts I found that my buddy had taken off.

Watched the YouTube video , looks like you need a starter , the bendix is shot , also when you were pumping the gas peddle was any gas being squirted into the barrels of the carb , if it was you may also have an ign problem , the vacuum lines were from the smog stuff ,

Hey guys.  What is the easiest way to replace the starter on this 2.8 Cologne engine?  I got the starter and go underneath the car to take the old one off but the subframe is in the way as well as some suspension components.  Is removing the suspension stuff the easiest way or is there some trick that I'm missing?  I can post pics if necessary.
