oil blowing out of oil filler neck
 

i bypassed my pcv valve, and i'm using a oil catch can. i blocked off one of the nipples from the oil filler neck, and routed the other one to the catch can.. on some days, there will be no oil in it at all, then others, like today, it got filled up(16 ounces) in a matter of about 30 miles worth of driving(lots of boosting/hard driving) is there a prob? is it hooked up wrong?

Mine did that too when Id rev it high and drive it hard. Mine also smoked though and is now dead though :) Good luck. Maybe its just regular blowby???:confused:

mine used to spit oil out of the filler tube nipples so i did what u have and blocked one and put a hose into a plastic bottle and it went in there, now ive taken the oil cap off and put 2 layers of fine stainless steel mesh over the top of the filler tube held on by a hose clamp to act as a breather filter, it was going to cost something like nzd $120 for a 47mm k & n breather filter so i made my own using the s/s mesh, alloy tape and a hose clamp, 2 days ago i went to the drag strip and did 10 x 1/4 mile runs and pre run burnouts and no oil came out the top or thru the tube to the catch bottle, so try that ! but then again i also changed the oil from 20w 50 mineral to Royal Purple 10w 40 fully synthetic, (im not using oil injection because i prefer to pre mix my petrol with Motul 800 2T 2 stroke oil) im not sure if that oil change made a difference to it at all, probably not.
