I have a 1996 r33 Gtst with about 180,000ks, stock turbo running 10 psi, plazmaman Front mount intercooler, new splitfires and new plugs, stock ecu. Recently i have been getting quite alot of white smoke on a cold start which increases when revved. It all goes away when car had warmed up. I did have some problems with a pcv vlave and also installed a catch can which i have taken off for the moment and installed all new hoses and i have replaced the pcv valve and grommet. I have done a chemical radiator test which came up neg everytime and there is no oil water mix. I did a compression test which was my first time ever and forgot to open the throttle! so dont know how accurate it is but results were: 1. 125 2. 125 3. 120 4. 120 5. 130 6. 130 i took the intake pipes off the turbo and there was a bit of shaft play in and out, a little bit more play than there was up and down. The intake pipes were pretty clean and no real signs of oil. Does this sound like turbo seal failure or leaking valve stem seals? Any help would be much appreciated

So here's the deal guys. I've got oil spraying out of my dipstick tube as well as pushing my dipstick out of the tube about 150mm each time. so clearly im getting pressure in the crank case but ive tried all i can think of now im out of options, so far ive: -replaced the PCV valve with a new genuine unit from nissan. -checked all breather hoses to make sure they weren't blocked. -done a compression test to make sure i wasn't getting excessive blow by that was causing oil to spray out. (read 140psi across all cylinders) now thats where ive hit a wall..... i cant think of anything else to check =\ any ideas? appreciate any help...thanks.

Breather tank/catch can/oil-air separator plumbing questions Hi all, Sorry, yet more questions. So, one of the previous owners of my car fitted a breather tank. Just before I acquired it it was looked over and some of the plumbing changed by Unigroup in Sydney. Attached are photos to show how it's plumbed in. From my research on this forum (very useful as always, thank you all!) and comparing to stock engine bays, it looks like the two breathers at the back of the cam cover are as stock, and are linked on the passenger's side to one of the turbos as stock. On the driver's side it's linked to the breather tank instead of linking to a PCV valve or whatever that thing on the side of the engine is, which is now blanked off. Currently the tank vents to the atmosphere through a little filter. The first aspect of this is I need to make it legal to pass rego. It only needs to be or look legal for 30mins, doesn't need to be an elegant solution. I tried blanking off the hose to the breather tank, but that either causes massive blow by or is pulling oil in large quantities from the top of the engine, as at idle it made piles of smoke. So I'm assuming the solutions are either to find a stock PCV valve and hose to connect onto the driver's side, or to take the filter out of the tank, hook that up to the pipe into the turbo, and blank off the passanger's side. Secondly, I'm curious if this setup is actually done properly. What makes more sense and what a lot of people on threads here seem to have done is blank off the turbo inlet and hook the passanger's side vent into the breather tank after combining with the driver's side pipe. Otherwise surely the system is still going back into the inlet charge, which defeats the purpose? Thank you very much for your help and time as always!

pcv system I've just been having a look at my pcv hoses and I took off the crossover hose with engine running and nothing happened. Isn't the engine supposed increase rpm if you take those hoses off? Could that mean there isn't vacuum? It did increase revs on my Subaru when I did that. There is also a lot of oil in my intake before the throttle body. I wasn't able to get the pcv valve out will try again later. I assume I should just get a new valve and grommet.

RB26 Front Crank Seal Failure - Help Hey guys, needing some expert help with diagnosing as engine breathing/ventilation stretches my problems solving! Ill give as much related info as I can; Car Is Stagea 260Rs, making around 290awkw with reimax oil pump gears (slightly larger clearances on the crank than OEM if that helps), no catch can or different breathing set up. Had an undetected oil leak for two days before a serious leak occured suddenly. Pulled engine out as I suspected fractured oil pump gears due to larger than OEM crank clearances. Turned out to be a failed front Crank seal, seal has spilt in half, spliting into two round bits and the metal inside the seal now looks like a kitchen sink scour. The seal was replaced less than 3,000km ago. Ive done some research on SAU to try find some answers, and Im led to believe its something to Do with crankcase ventilation, moreso pressurization of the crankcase. Ive also spotted oil in the pre turbo intakes, and ic piping. Car also gives smoke off on WOT. Any input would be appreciated
