b18 under boost.
Helping a friend of mine with a turbo ed b18c
explained of alot of blow bye, ALOT and to my surprise it does
compression test yielded a worn but not worn out engine at around 130-150lbs per cyl
its on only 8lbs and IS TUNED. heres what happens:
Upon initial inspection found the pcv routing to be exact oem, with no consideration of pressurization of the crank case from the turbo. took the time to correctly route a pcv system like as seen here http://www.beesandgoats.com/boostfaq/g2icturbo.html#PCV
then even took the time to engineer a 2 way system using check valves and retarted hoses.
in the end realized he had simply to much ring blow bye to offset a fresh air in and fumes out operation like can be seen in healthy engines.
it is simply constantly pushing air out of the pcv valve connection and valve cover inlet (now outlet) and yes it is pushing (alot) and not just pulsating, i know for sure!

MY Question is:
what is the bets way to deal with it, put 2 breathers on the system one on the valve cover and one where the oem pcv valve goes and just let it fume it self out??
my thought there is if there is no pcv valve or one way check valves and just open paths the crankcase and valve cover will reach lesser pressure on bolth ends than it would with ANY kind of restriction or valve being its pushing so hard from the pressure in the bottom end.....maybe even incorporate 2 catch cans to try and keep the filters cleaner.

or do u leave a pcv system on, and only leave the gasses one "easy" eascape and on the other end a pcv valve-drain system that is probably working in removing gases from the crankcase but cannot vacuum out more than is being compressed out.
the way i see it is it is like trying to tow a car at 5mph thats already trying to go 10
seems like the better release of energy is to remove all restricition.
i dunno what do you guys think?
besides rebuilding!
motor runs VERY strong is not hurt, just....gassey and old.
b18c itr head about 150k+ miles has cometic head gasket arp head bolts has been re-worked just unsure of exact work...

 

Sadly, the best option would be to rebuild or at least put new rings in. Rent a ball hone, put new rings in and put a better vent system in.

 

absolutely but were looking for the best way to DEAL with it as stated above WITHOUT rebuilding.
going back to the root of the question.
which pcv system is going to minimize additional pressure on the system.

the motor will eventually be rebuilt, again but at this time its not worth re-dooing until a little more funds set aside...

You sound well informed and may already know this but certain times in a motors life the rings will line up and allow excess blow bye. Is it constant and on more than one cylinder at a time? Also sometimes you can have build up. CAREFULLY try putting trans fluid through your intake to clean up excess build up. in valve train. BUT SERIOUSLY BE CAREFUL doing that it's a very good trick but risky

 

there is absoutly no point in trying to clean anything.
its a f-ing mess in there! a pcv system is pratically useless.
if the rings lined up great thats just another straw on the cammels back.
i dont know if its 1 cilinder or all, i certian one of the cilinders is f-ed up bad.
theres oil on all plugs at all times i put it to you that way BUT this motor still fires instantly and
outruns sti's daily.
