2.0 in 31 Ford Coupe
« on: March 24, 2006, 08:03:07 PM »
I just adapted and installed a fresh 2.0 to my 31 model A bell housing and got it on the road.  Runs great.  The problem (?) I have is that when I start it up cold I can hear just a small amout of noise in the bottom until it makes its 60 lbs. of oil pressure.  The noise is relatively insignificant but I'm afraid it could get worse with time.  I'm using a standard FRAM PH-8A filter which drains down each time you kill it so that a start up you have to pump the filter full of oil before it makes oil pressure for the bottom bearings.  Now my question.  Is there a filter that will fit that has a built-in check valve to prevent drain back or a 90 degree adapter that will turn the filter vertical?  Thanks

In a 2.0 you really should not have to worry about your oil filter, or, for that matter your oil pressure unless your oil pump is bad ( could produce up to 120+ pressure or 0 depending on whats wrong). I would not worry about oil drain down either. You should get pressure in about 1 sec. Even cranking the motor will give you a ton of oil pressure.
Yes, you can get a remote oil filter and mount the filter any way you want.

...or use a oil inter cooler and 90 degree off a late model 2.3 or other model engine. It should screw right on as they all use the same oil filter.

What oil pump did you use?

How fresh is the engine?

Clearances?

Try turning the engine over (ignition turned off) to build oil pressure before lighting it?

I used a Melling high volume pump.  The car has 29 miles on it.  Including running here in the shop for testing, etc. it probably has six to eight hours on it.  I vatted everything, bored it .040, decked the block (just enough to true it), milled the stock head, used a NOS stock cam, polished the crank (only needed polishing - went back standard), all new bearing and seals.  I've done lots of engines but this is my first 2.0 and OHC.  I would've used a 2.3 but the oil filter wouldn't clear the original steering box.

Hello 31 A Coupe,
 Did you use plasti-guage on the rod and main bearings before assy.?
Did you use NEW bearings?
 How much PEAK oil pressure do you have?
 The fact that you chose to polish the crank may be what is causing the noise.
 If you have enough room to pull the pan you couls find some .001 or .002 bearings.

 The melling Hi Volume pump is too much for most 2.0 engines.
 I have run them in the past but pressure spikes of over 100 pounds would blow fittings and soak the engine bay with oil.
 
 Are you running a manual tranny?
Did you tork the flywheel to the correct ft.pd.?
 Did you put lock tite on the flywheel bolts?

I adapted (with 1/2" plate) the 2.0 to the original Model A flywheel housing.  I had a machine shop build a 2-5/8" long hub drilled to the 2.0 crank bolt pattern to space the Model A flywheel rearward.  This had to be done to allow the use of the original Model A starter which bolts to the flywheel housing.  Part of the rear block flange had to be cut away where the Model A starter mounts.  It's really a pretty involved adaptation.  Everything worked out real well.  There was virtually no runout on the installed flywheel.  I had 25 lbs. machined off the original 63 lb. flywheel and had it re-drilled to accept a 67 Mustang pressure plate and used a Mustang clutch and Model A throwout bearing and transmission and everything from there back.  With the hood closed you can't tell it's not dead stock.  But cruising at 65-70 MPH is a giveaway.  Believe it or not, it really works nice and there is no detectable vibration.  The flywheel was torqued to specs with blue loc-tite.

It sounds like you have put a lot of thought into this project. I like the fabrication you have done. This is a great example of how we can think out of the box when using the 2.0/ 2.3 engines. I would love to see some pictures of your car.

Why would you want to run a C4 in a car that you could put ANY trans you wanted to in it????
