Rear main seal

[Fred5280]

Im going to do my rear main here soon. Im watching videos on youtube of people doing their rear main. Everyone replaces the gasket that goes beind the rear main thats bolted on but i cant for the life of me find a video showing what the gasket is in the middle of the 3 in this photo if any of you know what that gasket is for it would really help me out. Thank you guys

Not sure what that's for, I wouldn't lose any sleep over it. The set is likely intended for multiple applications. God knows what the middle gasket goes to.

True. I just didnt want go through with it and have that gasket sitting out when it was supposed to be in there somewhere. Thanks for the answer man

Nope, it's gonna be one or the other. And you already know which one.

Be sure to install the new seal WITHOUT any oil. The teflon seals need to be dry so they transfer a tiny bit of the seal material to the crankshaft so they will actually seal.

That's only IF that seal is teflon.

YES that is true and I should have mentioned that. Rubber seals get oiled. Funny thing when I replaced mine the teflon seal was the least expensive of the choices. That surprised me!

im thinking when i buy the seal ill have to contact felpro because they might be teflon but oreillys description says rubber

When you buy the Felpro seal kit, it will be written all over the box and on the inside sheets if it is teflon or rubber, and to install dry or not. You will find on Felpro "find my part", that you can get seal kits with rubber seals or teflon seals.

Also, the seal retainer gasket on my 5.7l when i replaced mine was baked on pretty good. I had to scrape long time to get it all off and cleaned surface.

Mine was also! I scraped and scraped on mine and it was baked to a crisp. I wound up using my die grinder with a 3M sanding disc to get it off. YES, I was very careful!!!!! Doesn't leak so must have done something right.
