Re: [DMCForum] vaccum under the valve covers?

["Andrei Cular" <acular@xxxxxxxxxxxxxxx>]

Well just go and look at almost any dragster, they pull purposely pull a
vacuum in the crankcase.  It serves several purposes, first any blowby
wont
pressurize the case and blow all the oil out, allows you to run low
tension
ring or and or larger gaps, and some people seem to think that by not
having
as much air behind the pistons they also move better.

go to www.summitracing.com or www.moroso.com and take a look at all the
different vacuum pump setups they have.

lol...you folks kill me ;)

It's amazing how myths get perpertrated over the years. Just looking
at the setup will show you there isn't. The oil filler breather piped
to the air cleaner? Looks like a normal PCV function to me. In fact,
if there is a car that has vacuum under the valve covers I'd like to
hear about it.
