Hey all.

I have a rb25 and recently oil spat out my blow off valve and through all my intercooler pipes/intercooler.

I was told by a mechanic that the oil seals were gone in the turbo so I replaced it and the oil line, cleaned all the pipes + cooler and it happened again..

Possible problem with the PCV valve or blowby from bad piston ring??

Any help would be great.

Thanks :)

Meh.... OIl in there is common I thought. The way the system is... Get urself an oil catch can setup and see its just coming through the breathers at the top, the hose that goes from one cam cover to another... Most likely shouldnt be there but there is oil in mine, always has been lol.

Well, there is a difference between the "always a little bit of oil there" amount and the amount that is required to come spitting out of the BOV. Any sudden increase in oil amount is not normal. I would in fact say that "normal" is none at all. My intake plumbing has always been dry.

    • For a daily just run Akebono ceramic pads. That's what they're optimized for. Obviously don't try to run it on track or anything like that.
    • Hey all, I'm sorry if this has been discussed before.  I have a 2008 Japanese import V36 coupe with nav but without Bose. I bought one of those AliExpress android screens, which for the most part works really well.  The only thing that doesn't work is the air con controls (well sort of) and the factory reverse camera.  The AC can be controlled fine but it doesn't report the change in temp and mode to the screen, and the volume knob/other audio controls from the panel don't register on the learning app.  I am pretty certain that the problem is the difference in the head unit between base model (Nav but no Bose) 2007-2009 coupes and anything after 2009.  Mine is the one with the blue connector all the way to the right as seen in this forum post:  The reason I think this is there is one wire left over that doesn't fit anywhere on this head unit, or in the factory screen which also uses different connectors to more recent versions.  I've seen the upgrade from OWC, and have sent the guy a message on eBay but no response yet.  I also don't particularly need the whole kit, just *maybe* an adapter for this one cable.  Did anyone else here have the same problem, or have any insight about what I can do to get this working?  I have been in contact with the seller but all they seem to be able to do is ask for more pictures and videos. Minor edit to add:  I have been researching and found a screen on Aliexpress that actually specifies my head unit in the listing, so these things do exist.  I will contact the seller to see if the wiring adapters are interchangeable with other screens.   Thanks in advance!
