PCV & oil burning U may be all wrong !!

I'll get you some links on Monday - sites showing how lowering pressure aids ring sealing and can actually increase HP at high RPM.

Just remember that we are talking pressure differentials and not vacume.  An engine with zero Hg. on a guage at the manifold actually has 14.7 P.S.I. of manifold pressure.  It is just equal to the pressure outside the manifold and thus no differential.  The goal is to keep the crankcase pressure from being above atmospheric to aid ring sealing.  It doesn't take much as it is acting upon a couple of inches of surface area on each ring.  An added benefit is the P.C.V. system removes combustion by products and stops formations of organic acids in the crankcase.  This is just Jr. high school science.  For those of you who don't run a P.C.V. system I suggest you change your oil very often and base that interval on time not miles.  How long do you want to leave sulfuric and hydrochloric acid on your engine parts?  Modern oils combat the acids with nuetralizing agents but these wear out quickly and cannot keep up with the formation of acids in engines that have excessive moisture in the crankcase or sit for a long period.  If you don't drive your vehicle much or for extended time then I would change the oil every couple of months at most, regardless of miles.  You could get some Ph. test strips and test the oil if you wanted.  You are looking for nuetral Ph.  You might be suprised the learn how acid your oil actually is. 

My PCV is sucking oil as well... the baffle on the bottom of the air gap intake only covers the pcv grommet.  The pcv I used is a purolator PV765 which seems to have a much higher flow than my old stock one.  Couldn't locate the Fram FV164DP locally and the two places I tried that had the standard motor products V164 were the big aluminum body style like my purolator, though Standard Motor goes under Blue Streak up here.  Popped my old pcv in and just ordered 3 NOS ones off ebay...unfortunately I don't know when I'll be able to do a road test as they are finally paving the gravel road that goes to our place, sure will be nice to have a dust free car!

Bill tell you what why dont you measure that so called vac in the crankase and get back to me.

Thanks raysinvegas, made the correction.
