IF anyone has anything to add please do so. The truck is a 94 but im not sure of the motor since i had to swap out the old one. Use the special seal driver to hammer in a new one (preferably the metal one, a part number would be great if anyone has one) that is lubed with vaseline. Pull out the new seal without damaging the crank. Please feel free to correct me if i am wrong in any of the following.

That way if i did have a leak in the valley in the future it would flow around the bell housing and not through it.Īfter reading through this site though from what i can gather i can change the seal without taking the motor out. I know the valley is dry and when i installed the motor i plug that stupid hole that would drop oil onto my clutch.

Mainly because when i had the front end of the truck raised today oil was dripping out from what appeared to be the rear main seal near the oil pan. After reading on here i am going to have to check the 'tuna can' and the oil pressure sensor. I was kind enough to take out the 4x4 assembly for him. Do to the fact i tried twice with no luck so i decided to place it in the hands of a more experienced person. I just had the oil pan replaced and new gasket installed by the shop next door. I believe i a have a leaky rear main seal. with as many problems as this seems to arise from this seal how come no one has written a walk through and placed it in the faq section? After reading through the FAQ and the search forum itself i still have a few questions.ġ.
