Re: just aquired 1931 Model A, help diagnosing oil leak

Look for the timing pin under the pulley. If the PO forgot to replace it, that's most likely where it is.


As for the backfire, it sounds like you have an intake leak and a rich carb. What carb...

Re: Hole in water jacket

Permatex #2. It does not get hard and will stop the seepage. I find many blocks that have the head studs drilled or rusted into the water jacket and this works unbelievably well. Does not harden to...

Re: Timing puzzle

How much rotational play do you have in the distributor cam when in the motor? Are you running a stock original cam, regrind, or a new cam? The gear on a stock or reground cam all have some wear on...

Re: Help rear main leak

Sounds like the builder didn't know how to rebuild the B engine. The pump in an A or B has the capability of as much as 100 PSI but without any restriction in the system, it won't push but about 2/3...

Re: Two piece crank shaft pulley

Cast iron pulleys fail from using pry bars to install or remove the engine. I use lots and have several originals that are perfect except for the seal area being worn. I don't see any reason why a...

Re: Motor Rebuilding

If you want babbitt bearings, you won't get them at AER.

Re: Mail Truck Engine Noise

I would drop the pan and inspect the bearings and check the clearance. The last 2 engines in my shop had bad bearings and a pronounced knock at higher RPM's. One had a bad rod bearing and showed...

Re: Tight Bearings

After adjusting the bearings to the correct clearance, this is often the case. Put it in and run it. After a couple of minutes it will work as before but with better clearances.

Re: Rear Main Leak Bear with me

You say it is a pressurized oil system, what seal was used in the rear cap and block?

Re: Main bearing bolts

People, these are not high speed, high RPM, high HP engines. Don't overthink it. Fords bolts have worked for 100 years and more. Why change them?

Re: Timing Gear Back Lash

This would only happen with aluminum cam gear. Fiber gears won't be noisy with .060 clearance. I have seen this. You probably need to check the valve adjustment or bearing clearance.

Re: Engine Knock Diagnostic Help Needed

Center main or possibly front main. Best to remove the pan and investigate before you damage something.

Re: Fuel pump

I have found that a 12 volt pump from NAPA will produce about 2-3 # pressure when connected to 6 volts. It works fine and won't over pressure the float.
I have done it many times.

Re: Oil Leak

I have never seen the oil leak from the rear main bolts. You have to check the thrust clearance on the rear main along with the crankshaft/bearing clearance. If the thrust is over .012 you will have...

Re: Main bearing oil leak

Originally there was no seal in the rear main. The seal that the vendors sell are modern "fixes" for leakers that don't work. I have found engines that have had ropes installed in the grooves that...

Re: Main bearing oil leak

Oil is controlled by bearing clearance only. If the bearing needs shims removed that will cause a leak. If the bearing clearances out between .002 and .0015 it is probably the thrust. You can check...

Re: Fort Wayne clutch claims setting is correct.

Ever wonder why there is an adjustment on the pedal? I have never seen a clutch assembly that didn't need any adjustment when installed new. Just part of the deal.

Re: Flywheel housing-horseshoe engine shims

Flywheel housing warped. I find most are after many, many years running without the shims.

I would like to know the axle position on a 34. Is the axle in front of or behind the spring? I know it is not directly under it like a Model A.

Re: Insert bearings

As long as I can pick up a ladle, babbitt will be poured. I agree with redmodelt that without pressure, babbitt is better.

Re: Oil Leak...I know i know, been asked 1000x!

I believe you have one or both of 2 problems. The rear main is out of clearance and has too much thrust or, the babbitt on the rear main is broken and pieces are missing. The only cure for the broken...

You can keep on wishing the head and block are flat but, in my opinion, something is warped and needs to be machined flat. The areas you show where #2 and #3 are leaking to the outside of the engine...
