Hi David, I am sure you know that the side seals should be soaked in oil before installation. Based on what I have read over the years, for my last few engines I have applied Silicon gasket maker to the parting line of the rear main seals just before installation. Also, I pack the rear cavity with the gasket maker after the engine is together. So far, over several years, none of the engines leak from the rear seal. I always use a NAPA press on damper sleeve to give a new surface for the front seal. Again, no leaks. I always put a windage tray in my engines, they all have some aspect of performance, even if just a street engine. I believe the leaks from the oil pan come from over-tightening. I always make sure the oil pan sealing surface is perfectly flat. If the lip or bolt hole edges need dinging down to make them flush, that is what happens. Again, I use the gasket maker on all the gasket surfaces and then tighten the oil pan bolts pretty snug with my hand cupping the ratchet head so it is essentially a nut driver. This keeps me from squeezing the double gasket out. That is just my method, but it has worked well for me. Bill Huff At 7/12/200802:55 PM, david dumais wrote: >Had an oops !
