?I have replaced the rear main Seal ( two Piece) twice and it still is leaking a lot of oil. Anyone have advise on any things I might try to seal it up. Is there a trick to know while replacing that seal?

Nik

Nik: There are definately right & wrong ways to install rear main seals. One place to get a good procedure is to link from here to Ted Eaton's site, where there is an extensive instruction page on rear seals. Also there are other places for leaks that may appear as main seal leaks. There is a Cam shaft plug at the rear of the engine that can also leak. It should be installed with sealer. However, Ted cautions when installing that plug, not to drive it in so it's tight against the cam, as doing so can cause damage to the spacer at the cam's front. Also the Valley cover gasket can be leaking at the rear or even a leak at the oil pump mounting area...

There are other areas that will leak and show up as a rear main leak. Did you check your cam freeze plug above the crank shaft to be sure that it is not leaking? Have you looked at the adapter seal for the spin on oil filter? These two culprits have gotten away clean for years because everybody automatically blame the rear main seal.

What?

There is another area which bit me once driving a newly bought 55 from St Louis to Maine that happened in mid New York was somebody tightened the two center rear bolts on the oil pan which thread into the rear main seal too tight. The rear main is aluminum and goes into the pressurized oil area and when the threads are damaged in this area you will get a leak. Lucky for me as I was at a gas station checking it out and just as I found the culpret a gentleman informed me he had a good supply of nuts and bolts back at his farm not far away. I followed him over there and found a couple metric self tappers slightly larger, wound them in there and never had the problem again. that was the same motor I went to Columbus with in my 58 truck and those pan bolts were still in the rear seal area, never leaked a drop since.

I'd like to know how you can check the cam plug, You'd have to pull the trans for that.. It could be a possiblity, My leak seems to start halfway up and between the block and trans...??

Good tip Billy..

Talkwrench-I have the same problem with my rebuilt 292.I used the "Best" rear main seal and followed Ted's instructions.I have a leak after its shut off and sits.Doesn't seem to drip while its running.I am trying one of those "Stopleak" additives before I do anything more invasive.I have checked the oil filter adapter and its not coming from the valley cover as I fixed that so it will never leak.Drilled and tapped for machine screws.I am thinking maybe the rear camshaft plug also.Interested to hear some replies to that question.

  

Yeah, Ive been all over this leaking business [ and the brakes issue] I just let it leak Pfft! Its hard sometimes when I visit friends I park out on the road and not in their driveway..Guess I could leave my mark ..

I used the new neopreme seals on my last build. So far no leaks! I have to recommend them. They worked for me. Chuck
