BOV Blowing Oil

**drader** · 08-04-2011, 02:11 AM

So I was at a drift event and it was hot out, but the car was running nice and cool all day as indicated by the temp gauge. When I popped the hood after a few runs I noticed the was oil in the horn of my bov, and there was oil on the radiator(where my bov is pointing).
Why is my bov shooting oil?? There was no smoke coming from the exhaust or anything like that. Power did not decrease, there was really no indication of anything being wrong except for the oily bov/radiator.

Should I be worried, is this normal?

Sounds like excessive blowby. Check your intake piping it's probably full of it.

What are you running, rb25?

Do you have a stock turbo still? It's normal to an extent. Blowing out of the bovs seems a bit extensive. You should take off your downpipe off and check for oil on the turbine. Also remove all intercooler piping and give them a good wash, get all the oil and junk out. Then replace. Check back in a couple of weeks and see if there is excessive oil. If there is it could be a blown oil seal or blown turbo.

Edit: sorry mate just saw you posted "stock rb20"
