Oil Through Intercooler / Out Bov

[aaronb]

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

Damaged piston(s) and/or ring(s) leading suspects.

^^ was for me. Try a compression test.

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.

couple of things -

- What turbo are you running?

- Are you bouncing the limiter a lot

- HOw many Kms has the engine done

- Have you upped the boost \ trashed it

You might have a replaced a blown turbo with a blown turbo. Did you replace it with a used factory unit?

Brand new turbo. GT3076

139000 genuine

Boost the same.. 1 bar at hi.. 11 psi low..

Nope not on the rev limiter only happens when under a bit of load but..

Yes the oil fully comes out into the engine bay out the BOV.

Nothing to do with the PCV valve at all??

Can you confirm the restrictors are fitted to the oil feed in the turbo?

Definitely have a look at the PCV
