As far as rear main seals -- it's all in preparation. I have always &quot;dressed&quot; the edge of the main cap and block where they slide into the groove on the seal. You don't want to &quot;shave&quot; and material off the seal during installation. Also, I apply a dab of Hi-Tack to the main parting surface (between cap and block) to prevent oil from seeping between them. Another &quot;trick&quot; is to off-set the seal parting lines -- I've installed them both ways ... doesn't seem to make any difference if seal is installed carefully. If available for your application -- use the one piece pan gasket. This has worked for me on both SBC and BBC engines. TAZ [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img] </div></div>

I know all the &quot;tricks&quot; to installing seals, but I think you'll find that I am not the only one who has had issues with the current fel-pro rear main seals, even using all of the proper techniques. </div></div>

Another issue that may cause this is excessive pressure in the crankcase -- valve cover breathers, etc. not fuctioning as advertised ... but then too, maybe I’ve just been lucky ... TAZ [img]<<GRAEMLIN_URL>>/dunno.gif[/img]
