Dorman635-518 Engine Rear Main Seal Cover Compatible with Select Models

Installed on an 05 5.3. Great quality and no issues! No leaks, fit like oem.

Wow fixed my oil leak and fit perfect no issues on the install great product A+++++

These are great covers. Beets spending a ridiculous price on OE or just changing out the seal.

If you have oil dripping down between the engine and transmission then this is the seal to replace. You have to pull the transmission to get access or a least slide the transmission back far enough to have room to work. I did this in a gravel driveway with a jack on 4x8 plywood & ratchet straps. One strap & wood block to hold the convertor in place. I did not use the “Doorman installation tool” I installed it using light even pressure alternating between bolts to keep the new seal plate as flat to the engine block as possible. Following up with the correct tightening pattern & torque spec. It’s been over a year and no leaks. The old plate seal was so brittle it cracked in several places.

I was going to replace just the seal but I opted for the whole assembly. It's been 2 weeks and no oil drops. Take your time and follow the instructions.

Product comes with the seal installed. Careful installation allows it to work properly. With the crankshaft cleaned very well, no rust or sharp edges you slip the new seal in place dry and clean. No Oil or grease because this is a teflon seal. Once fully in place by hand start all the upper bolts and then install the lower pan two long bolts leaving all bolts loose. Slowly tighten the upper bolts working around the seal area first, letting the seal be put in place centered on the crankshaft so you get long life. Now torque the upper bolts first and finish by tightening the lower bolts and torqueing them. You read of lots of guys saying this does not work and leaks. They installed it wrong in most cases. IF you tighten the lower 2 long bolts first the seal will egg shape on the crankshaft and leak. If you don't tighten the upper bolts slowly working your way around the seal and gradually bringing the entire plate tight against the block you will cause issues and maybe even break the new plate. Follow procedure and it works.

Works great

First time I've had a 5.3 or any LS engine that doesn’t leak oil near the rear main. I had to pull my transmission so the labor was free.

Didnt need the centering tool for this kit.Followed torque sequence and no leaks.

This product worked amazing no more leaks!!!

So far so good perfect fit very happy
