REAR MAIN SEAL SEAL
I use RTV on the back side of most rear main seals. This is a great safety measure on rubber seals and a must on early rope rear main seal style blocks when using a neoprene type conversion seal. Splitting the alignment of the seal to block is always a good idea. Excessive use of RTV in any application can be detrimental to the engine.
