Oil in intake

Currently running R34 N1 turbos AA403, noticed some oil in the intake, though I have already installed a nismo catch can. More than likely the front seals I just ordered some .8mm restrictors. But whats the chances of there being oil in my intercooler and it's blowing back into my intake via the bov recirculation?

You need to clean out any part of the intake system where oil can pool. It's likely your intercooler is holding a lot of oil. 

Correct me if i'm wrong but the turbos should already have a restrictor built in should they not? Also if oil was pushing out the front seal it would be pushing out the back seal and pumping white smoke out the exhaust.

How many litres is that can? It doesn't look big enough to allow a vent filter on the top, if it fills you will have a potentially dangerous mess.

Im in the process of ordering a intercooler from plazmaman, going to clean out all the piping then. The car should have stock oil restrictors. Bought a set just in case. The nismo catch can, is  recirculated back into the oil pan via the oil return line on the rear turbo.

      Squeaky bushes

      By GTSBoy · Posted

      Just install a grease nipple into the centre of the outer steel of the FUCA. Make sure the bushes aren't long enough to touch each other underneath that nipple. Cut a few mm off each if need be. Then you can push grease in there while it is all assembled. That was the very first thing I did (to all 4 ends) of the FUCAs on my 32 when I put Whiteline adjustable bushes into them. They would squeeze the grease out real fast, and I could squeeze it back in faster.

      @GTSBoy I found the issue (sort of) when I took apart the bushing again, it was completely dry inside! When I experimented with it, all the grease would push out when I would compress the bushings. I wonder if this has anything to do with me putting in the poly bush first on both sides and then pushing in the metal barrel. Maybe I should have put in the metal barrel first then the rubber bushings so the spread pattern is different.   It's fixed (for now).

      Can't put strut back

      Just redid that entire job. 4 hours, but tightened everything properly. Had to jack the rotor instead of having the car on blocks as there was no room for the FUCA arms to tighten and the j arm. All good now. Cheers for the help!

      I would sell those side feeds before you hydra-lock a motor. I won't say too much about Yellow Jackets because I'll hurt people's feelings, however ask those that tune RBs day in/out what they think of them.

      The 1000ccs are side feeds but they're not currently installed, had my old factory ones in for leak testing purposes, only decided on them because front facing plenums and good top feed rail kits are out of my budget at the moment, are they really that problematic? Had a set of yellow jackets that lasted me 5 years, no real issues, only replaced them chasing this misfire issue that ended up not being ignition related 😄
