I seem to be having a problem with my crank case pressure under boost. I either blow it out the dipstick tube or the rear main if I zip tie lipstick tube in.

Any advice on a vacuum pump/ oil catch can diagram? I have a PVC in drivers valve cover and a hose from passenger valve cover to oil catch can. if I hook. vacuum pump to other side of oil catch can do you think this will cure my issue?

 

I have all my pcv openings vented to the atmosphere and I dd the car 110 miles a day 4 days a week and have no problems. It regularly sees 9lbs boost and has 203k on the engine, 30k with the setup like it is, what else would you like to know?

 

I highly recommend the Saikou Michi dual can with the following routing. It creates crankcase vacuum under all conditions and will be much cheaper/easier than a vacuum pump. Myself and others have run this setup and it seems to work very well...

 

this, and mine regularly see 20lbs of boost.

do a compression check if you are pushing the dipstick

 

Ok I will try this.

I have tried venting to atmosphere only on both sides. it makes mine smoke out the exhaust bad. I was told by machines that I had to run a PVC in one valve cover because of the design of the oil tubes in engine block. he says without the vacuum being pulled it will cause my oil return line to turbo to back up and smoke thru turbo.

I'm going to do a cyl leak down test this weekend. I really don't think anything internal is hurt. it has no blow by at idle or reviving. only under boost. I'm pushing 20+ so its finding all the little gaps for sure.
