rear main leak

I just resolved the same problem. On the 1st round I went with the 'ol pushing in the "so called pipe cleaners" into the rtv & ended up with a slow drip. I honestly believe that most of people's problems are in the sides of the rear main bearing seal cap. I always offset the seals a bit. I personally will not do another 440 without a Mancini seal kit or a 440 source seal kit. (any of them that has the 2 rubber seals for the sides of the aluminum cap). I also found that 1 of the 2 bolt heads didn't leave much to grab a hold of (even though it's only 30 ft/lbs). So I went with allen bolts._00a2.JPG _00 a1.JPG ] _00a3.JPG Yep, I rtv'd the sides, corners and the slots where the seals sit.
