Projects BANGER WIZARD IN LAS VEGAS....NEEDED!!!

what I'd like to do is find some one that can pull the motor, fix the leak and put it back..
looking for the wizard of A"s .. I can"t find anyone in vegas that can or would do it... .. might have to haul it to B master in paso robles..

 

is the seal between the oil pan and the rear main cap installed ?

 

Recently, I had the same exact issue with my B engine. Leaked oil everywhere from the rear and after pulling the engine, I learned that the engine builder owning it before me forgot to install the rear main seal in the block.
I installed the RMOS insert in the block and it never leaked again.
I was running a B with high comp head and dual carbs. I’d suggest making sure you have the B oil breather tube also, The B tube is larger diameter than the A. B tubes are hard to find.

here's the real problem..not knowing what I'm looking at....I've had this apart multiple times... and not knowing I keep putting it back... the first time I never even knew there was supposed to be a drain pipe on the rear main.. was told it "HAS" to be there or you get leaks.. soooo, took it back apart and put it in... then talking to "WIZARDS of A's, half say you don't need it on an insert bearing "B" motor... this is one of those internet problems that will never get fix'd with non knowing people working on it.... and for sure never get fix'd with out wrenching on it.. very greatfull for this site and all the suggestions of what it could be,... but with out someone that knows what they're looking at when it's apart,.. probley never get fix'd... My guys at my shop don't wanna work on it for that very reason... too much time waisted..when they could be making money doing what they know how to do....doesn't seem to be anyone in vegas that still works on these.. most likely the motor needs to come out.. or the trans for sure... but ... who knows...might be simple... might be major... so still looking for a wrench that knows and works on these.. would love to find the guy who built this motor... lots of questions...
but.. as for now... I don't have time nor the want to pull this apart again on a "I THINK SO" repair


so still looking for some one to fix this oil leak... even willing to haul it on the trailer to some one close to vegas.... but for sure not gonna do it my self...

 

OH,... and just so every one knows,... not looking for a free be... willing to pay for the repair..

 

here's some thing else I found... if the fly wheel bolts are 1/16'' too long they can cause this problem... , so leads me to believe that who ever built the motor didn't install it??? but will surely get the blame...

 

Double check that it isn't the side cover (valve cover) leaking and running down. dripping off the back of the engine.
This can occur, especially if the engine has been modified for pressure oiling...plus it is an easy look

 

did that...

here's some more forensic clues... and seems to always happen to me...

when I bought the caar, was told the oil leak is the pan gasket.. and here's a new one, just didn't have time to install it.... also gave me a Les Andrews repair mauual... funny thing I found... on the section about the rear main there's greasy hand prints on the pages about the rear main... could it be that the p.o. found out the motor had to come out and sent it down the road...??? LOL... thats my guess...

 

I don't have an answer for you, sorry.
I will point you to a few things that might help you understand what's in there and how things go together from different viewpoints. I'm sure there are a ton more, but these ones are bona fide.

good timing on this plea for help. I'm having the same issue with my pile. Does something similar. The po of the engine in this one had screwed up the threads for the tube in the main cap and i think that may be the source of my dilemma. Too bad as all the bearing surfaces have new Babbit. Going to need to drop the pan but I'm getting pretty good at that.

 

nice heep

 

Not being able o see what the rear bearing and seal look like, it's hard to say if it's actually the cause of the leak. It looks to me, however, that the amount of oil leaking out is too much for the common rear seal leak. I'm betting on the leak is coming from the rear cam bearing. The gasket between the engine block and flywheel housing may be damaged or missing. Also, the "B" oil pan must be modified to use in a stock Model A. In doing so it could have been damaged at that point.

 

If you don't have the seal part shown in the CW Moss picture, that's a big problem, and probably the only problem. It's a must have for the slinger to work properly. It's possible to install it without pulling the engine by just rolling it in around the crankshaft. If you have to get help with your engine and can't find it in Vegas, take it to H&H Flatheads in the L.A. area. They specialize in such things.

 

There's a guy in Phoenix that could probably help if you can't find someone closer. I would need to dig up his contact info.

 

Do you have any pic of the crank with the rear main cap off ?
has the oil slinger been turned down or cut off for a modern style seal ?
if the oil slinger has been turned down , has all the burrs been taken of and edge rounded ?
I have seen a lot of the modern seal cut and nick when being installed
does the rear main have shims ? were the shims push in close to the crank to seal any oil leaks

 

no slinger//

 

Does it have a seal ? is the seal cracked , nicked or broken ??

The good news is if the gasket is missing you should be able to tell by looking. Also did you remember the shims that allow for the thickness of the gasket?

If you are pulling the motor out you need to check the end play in the crankshaft. should be .002"
If the flywheel housing was not dialed in so the mounting face is parallel to the end of the crankshaft/flywheel, disengaging the clutch will put unequal pressure on the face of the rear main thrust bearing surface and wear it out prematurely. Once the clearance increases the possibility of oil leaking through the rear main will increase.

It appears you may have a pressurized motor. It looks like they have blocked off the top of the oil pump and routed the oil out of the side of the block into the oil filter. From the oil filter it appears there is a dump line running to the side cam gear cover and I would believe that there should be another line running to the bottom of the valve cover where the pressurized oil would enter the cavity running along the bottom of the valve chamber. If you pull off the valve cover you should see 5 holes, 3 leading to the three main bearings and an extra hole on each end running to the cam bearings. The holes running to the cam bearings are normally tapped and a set screw that has a .030" hole drilled through is installed to limit the amount of oil going to the cam bearings. If these are not present then you could have an anormal amount of oil going to the rear cam bearing and subsequently oil leaking out the back of the cam bearing as only the flywheel housing matches up against the back of the camshaft (with maybe a paper gasket also installed. In a pressurized motor some form of a seal need to be installed to contain the pressurized oil at the back of the rear cam bearing.

 

Lotta good and helpful Banger folks in this thread.
I get the OPs issue, bum health (shoulder I think?) that limits his ability to get after it. Would be nice if someone nearby could crawl under and have some looks at it. Maybe even turn a few wrenches.

 

pretty much where i'm at is i don't want to have some one take it apart, and not know what to look for, put it back together and it still leaks...

 

pretty much where i'm at is looking for a shop that can pull the motor that does this kinda stuff... some one that will look at it and say, this is why it leaks so much...seems as big as vegas has got that there would be someone or a shop that does this kinda work...doesn't do much good if you don't already know what you are looking at...like when I dropped the pan the first time... didn't know about the drain pipe so it came apart again and the pipe was installed ,,, then now there's quit a few that say it's not needed on my type of motor... don't wanna keep doing this... would also like to find who built the motor, and what was done to it

their site is down for some reason...

 

just sent you pm

 

You might go over to Ford Barn and post your dilema there and get some local help- good group over there as well as here.

 

It was up a week ago when I posted the link. Here is the MAFCA site with an email and phone contact. https://www.mafca.com/chapters/NV.html

 

Have you plasti-gaged the rear main? It may be oversize
