Hey guys, I have replaced my rear main seal 5 times now, I have tried 2 billet mancini styles, 1 440 source style, and reused the stock one twice. and have always had the pesky drip, and yes they are installed correct way around and no it is not leaky from anywhere else, I have checked the oil galleys in the back and the oil pressure sender location and all dry.
I have the sump off again and going to try and stop this leak once and for all.
my question is what is the best way to do this and whats the best type/brand seal to use. Where is the best place to use the RTV silicone?
Do you put silicone is item "A" the cup where the seal sits?
Do you put silicone down the sides in "B" where the side seals sit?
I am going to remove the 5 main bearing holder so I can get some rtv on the join between the block and seal holder as well. I am using arp main studs so I have to grind a groove out of the seal holder as well.
