NSNPWR Posted May 14, 2011 Share Posted May 14, 2011 (edited) Just wondering if anyone else has experienced this with their 26s... I recently installed one of the over cam cover, barrel style oil/air separators on my 32 GTR, was previously running the factory lines without issue. Has been running the can now for about a week, got home last night after giving it a bit of stick (revved it to 7200 a few times max) and noticed oil on the driveway, popped bonnet and noticed the dipstick had popped out and allowed oil to blow on the drivers side inner guard... Now, ive had motors in the past with busted pistons and broken ringlands and know that this can be an indicator that all is not well but i'm 100% sure that the motor is healthy, its a forged build and only running 11psi with knock reading no higher than 30 on average... I run it about 500ml over filled with oil... Im convinced this can is causing a restriction and creating excess crankcase pressure causing it to look for other ways out ie. via the dipstick tube... Has anyone else had this issue with this style of separator? Pic of install, any issues anyone can see???

PM-R33 Posted May 14, 2011 Share Posted May 14, 2011 There has to be a restriction there causing the crank case to pressurise. Since I've never used on of those, what is inside? Just hollow?

SiR_RB Posted May 14, 2011 Share Posted May 14, 2011 I've got the same catch can and it works 100% fine...could your dipstick O-ring be worn and too loose causing it to pop out.

DVS JEZ Posted May 14, 2011 Share Posted May 14, 2011 Ive got one runningperfectly fine. Its got a pipe between the 2 hoses inside the cylinder/can. In that pipe there is a small slit venting into the can. Try putting electrical tape around the dipstick so its a tighter fit. If that doesnt work try running the car without it and see if it still pops the dipstick out.

NSNPWR Posted May 14, 2011 Author Share Posted May 14, 2011 Cool, this is the same, small slit in the tube running through the guts of the can...I was running nothing previously and the dipstick never popped out, ever... Does the install look correct? Ive seen one where someone had looped the 2 side breathers around the back so they connected up but doing this this wouldnt really provide any extra ventilation as such? And I blew threw the can easy as before I fitted it so pretty sure theres no restriction in the can itself, my only concern with the install is the 90 degree elbow on the drivers side line from the PCV, not ideal.

Fullboost_Performance Posted May 14, 2011 Share Posted May 14, 2011 I have the same setup on mine, just make sure all the hoses are still flowing easily, and the 90degree hose isnt kinking on the inside, also remove the pcv and clean it out with some throttlebody/carby cleaner, the valve may be sticking....good luck Link to comment https://www.sau.com.au/forums/topic/364214-oilair-separator-install-on-rb26/#findComment-5812899 Share on other sites More sharing options...
NSNPWR Posted May 16, 2011 Author Share Posted May 16, 2011 Thanks for the replies all...wondering did you guys retain the little restrictor in the line running to the turbo inlet? I was able to use the factory line and noticed when I had it off that it had a little metal restrictor/filter(?) inside it...
