Hi guys,

I recently changed my spak plugs and found 1 of the spark plug tubes had oil covered at the bottom of it. The old spark plug had oil on it as well.

The 6th cylinder seems to only have the leak which is the one closest to the firewall, passenger side bank.

I know this is a common problem, has anyone attempted to fix this? It is the rocker cover gasket that requires replacement ? Are there any other gaskets that surround each individual spark plug they may also be the cause or is it the rocker cover gasket only that exists. Your help is appreciated

Cheers

Not sure on that one but I was definately able to replace. I have the invoice at home somewhere. Apparently it was a bit of a tough job getting them out but eventually was done. Fixed the oil pooling problem in any case :)

Japav,

Do what I did....Just wipe it all clean and shove a towel to soak up the excess in the sparkplug well...then screw the new spark in....i did mine 3,000kms ago and no issues - plus, I got better fuel economy with the new sparks.

I honestly would have had the leak fixed, but since my old man said it was fine, then I wasn't as worried...

And, by the way, the leak is 'always' found on the cylinder closest to the driver...the rest are fine.

I think you mean passenger side cylinder closest to the firewall, yes?

I've heard cleaning the sparkplug well and then running some high temp silicone with your fingers along the side works to cover any minor cracks in the seals as well.

Can be any plug that fills up, just most likely the rear ones.

I found the quickest way to remove the oil is with a big syringe with some rubber hose on the end.

If you can get some silicone under the rubber with a small flat blade screwdriver it should seal pretty well but I would suggest removing the rocker cover to do the job.

      Blue Smoke from exhaust, RB25DE+T

      By MBS206 · Posted

      Stock R33 boost control, with the exhaust, and FMIC done, will boost creep. There is no tuning around it if it is the factory boost solenoid.   If it has an aftermarket electronic boost controller, the settings/mapping can be altered in it.   Oil could be anything as mentioned, however did it ever do it before you did the turbo swap? How much and how often did you drive the car before the swap?   I'm hinging on too much oil supply, or it's not draining properly.   To check, pull the air outlet off the turbo. Is it full of oil? Drop the exhaust at the turbo, does it appears to be oiled/coked? Now pull turbo and check the exhaust manifold, does it appears oiled and coked the same way?   Secondly, the PCV could even be stuffed / not functioning properly and will cause blowing of blue smoke.

      Like loud exhausts? You could be a psychopath.

      No "could" about it.

      rb20de neo +t conversion - boost pressure sensor needed?

      By GTSBoy · Posted

      Almost any ECU would work, from a 30 yr old PowerFC to a new Motec/Autronic. But presumably you want new middle of the road ECU, meaning that you want a Haltech or a Link, most likely. As to which model though? I dunno. I don't keep track of what they have in their current ranges. You don't want a plug in though, because plug ins can start to cause you the same wiring issues that you have to chase up with your stock ECU/loom swaps when an engine transplant is involved. If you use a Haltech (and presumably a Link) you could put the base map for the engine in and drive it around and not even need to "tune" it. It will work just fine. I can't recommend a tuner without a location (and even then I can't recommend many, being as I never use any tuners except myself and my brother-in-law). And not many tuners are happy to remote tune. Maybe they'd be happier doing it for a basically stock setup that just needs to be demonstrated to be working properly. But even then, not being able to be with the car to see what the hell is going on and sort out the inevitable problems that will result from an engine conversion done by an amateur..... unlikely to be enthusiastic about the job. And if you think that just adding 2 wires for the boost sensor is difficult - you don't want to be trying to install and set up an aftermarket ECU. You're going to have to bite down hard on something with either approach.

      Wiring loom difference between A31 A/T RB20DET and R32 M/T RB20DET?

      wired everything up and confirmed that the red with white stripe is indeed the fuel pump pin on this harness.
