Hello, I have a 1967 Ford Mustang Coupe, I seem to be leaking quite a bit of dark oil under my torque converter, I think I may have a rear main seal leak.  Are these hard to repair, do I need to remove the engine, or just take down the oil pan and replace the gasket, any info would be much appreciated!!! Thanks!Cry

you can take the pan off but with the 2 piece rear main seal it's a Bitch to do under the car your looking at about 2-4 hours..just take your time but make sure your front seal on the trans isn't leaking too. if both are leaking I'd pull both engine and trans as a whole..this way while the pan is off I'd put in a new oil pump,screen and pull a main and rod bearing to check for wear...you can buy a "plastic gauge" at NAPA for about 2.00 and check clearance.


when reinstalling oil pan clean it well inside and out..go ahead and put a fresh coat on paint on it and put in a magnet oil drain plug..


how this helps

I would pull the engine with out the trans it will be eaiser to handle when trying to remove it. All you have to do is remove the torque converter bolts and the bell housing bolts and the starter. It is a walk in the park and inspect the trans front seal if it looks ok let it be and spend you time and effort on the motor.

Even if the front pump seal is OK I would change it anyways, cheap insurance for a couple bucks.  I would prefer to just pull the tranny as opposed to the whole thing if all your gonna do is change some seals.

You should know that it is a pain in the ass to pull the trans and engine at the same time and its even harder to stuff it back in when the are bolted together. and if he is going to replace the seals they will need to come apart so why not make the job easier and do them one at a time.

I have seen engines take an hour plus just to alin. the dowels on the engine/trans..now if I had a big block to put in it may be a lil different...in my younger years we had a racing team..we were all in high school and rented a shop...we would run a car..as we street raced ...bring it back and you and engine /trans swap and be back out in around 2 hours...man it was fun but a ton of work..all worth it to see the looks on guys faces when you go up the with a lil ole 350 350 hp and come come back with a 400  550 hp. there was 6 of us with 5 street cars and 1 drag car. to see what 6 poor people could do was awsum...
