I have a y8 with a 15g, and I think its a good idea to put a restrictor on it, just trying to decide which one/what psi? How low is okay? I am running a vented crankcase, just opened, not running vacuum, so I might (will ) have more crankcase pressure than stock/ideal. I saw a cheap oil restrictor on ebay for 30psi for like $15, think that pressure is good bad, too much too little. Hopefully greddy will answer some calls.

 

at idle 5 psi is okay and then max 25-35
and you better keep your pcv hooked up if you dont correctly vent your bottom end you will start to get blow by past your rings. its cheap to do it right.

 

.065 restrictor.
