Re: [Chrysler300] Try Again

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.
