Folks, I'd like to start a thread topic here on how you personally install your FE rear main seals to insure there is absolutely positively no leak. I've done my rear main on my new 428 three times now and I'm still getting a 3" puddle under the car after a few days of sitting, so obviously I'm not doing something right.
On my last attempt I used the following process with no better results than my prior attempts:
1. Clean the rear main cap spotlessly.
2. Install the upper seal in the cap, dab a small bit of Right Stuff on the upper seal surface that will contact the seal on the bottom (actually the top) seal already in the block.
3. Use a super, super thin coat of copper coat sealant on the cap mating surface that will contact the block horizontally. Never did this before, but figured with two failed attempts prior it was worth a try but obviously didn't help this time.
3. Install cap into the block and torque to spec.
4. Sand the side seals down until they will slide with a little effort all the way into the side seal bores.
5. Lube up the side seals with Right-Stuff sealant and install them all the way in, minus 1/2" exposed above the cap surface.
6. Drive the pins in and thus drive the side seals the rest of the way, use a small pin punch to make sure the pins are below the pan rail surface.
7. When installing the windage tray and oil pan use a small smear of Right Stuff over the main cap edges and side seal holes.
There is this topc on the rear main crush, which I've never really paid attention to before, but maybe it's time to look into?
http://fepower.net/simplemachinesforum/index.php?topic=410What are everyones thoughts on offsetting the upper and lower seals so they are not in line with the block and main cap mating surfaces? Is this the secret trick?
I think this thread would be very beneficial to those searching out there for how to do this right. There is a correct proceedure, step by step that we should be following to do this correctly and I know I would personally love to know what it is to make sure the rear main install goes smoothly the first time. Thanks all!
