Oil/air Separator Install On Rb26

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???

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.

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.

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

      What should I do next to hold the head on

      By Gareth87 · Posted

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
