Hi all,

iv noticed that the join point for the upper n lower halves of the plenum on my RB25DET is starting to slightly weep some oil residue.

Just wondering what would cause this?

Iv got the whole blocked PCV valve, catch can etc and have vitually no valve blowby and no oil makes it back from this system to where the pipe ends in front of the turbo intake (i.e. non-atmoventing catch can)

My old stock turbo was leaking some oil from the seals but I wouldnt have thought it would make it all the way along the system, throught FMIC etc to the plenum...

thoughts?

ah gotcha.

Nah no white smoke, never was.

yeah iv got a fresh turbo on there now so shouldnt be anymore coming through to compound the problem, but will prob put that gasket replacement on the 'R33 list of things to do'.

Just did the cam cover gaskets :s

      That looks good, but I think you're going to need much beefier side skirts now.

      They are daft and there's a reason it never caught on. Steering feel? We don't need no stinking steering feel!

      I gotta pull you up on this. It's driving me crazy. A shutter is something that closes, like over a window or in a cmera. The word you want is shudder. That LSD is clearly f**ked. Take it to a diff shop and get it disassembled and examined by an expert. YOu might have plates welded together or something equally crazy.

      S1 rb25/s14 starting problem

      By GTSBoy · Posted

      Check the Nistune doco. There are a few assumptions being made here that might not be valid. I will list the things that occur to me: Base map. Base map for what? Base map for Z32? Then the cranking pulse width is probably wrong for an RB25. The extra 500cc of capacity might well be enough to prevent it from catching. Base map for RB25? I don't think you can load one of those into a Z32. You have to just make the settings correct for an RB25 in the Z32 base map. That is either K or the TIM to get the pulsewidth right. Loom. You bought a loom for an RB. And you plugged it into a Z32 ECU. Did you make sure that any iwre differences were swapped. From memory, there's at least a couple. And as per the others, I would suggest making sure that the fuel pressure is correct while cranking and that the injectors are actually flowing as expected. They really must come out and go on the bench, unless you do find that you have messed up as per above points. I would also suggest watching in Nistune to make sure that everything is reading correctly. That the correct binary flags are raised at the right time (like the crank signal), that there's no stupid values in K or TIM. That you have not got mismatched firmware for the ECU and/or a wrong image loaded.
