When I installed my turbo I put a small amount of oil down the oil inlet hole. A small amount had spilled on the exhaust manifold. I cleaned it with a rag, then sprayed some parts cleaner on it. I had blue smoke for at least 4 hours, and that was from a small spill. I'd imagine if even a tiny amount of oil was anywhere in the intake track it would cause some blue smoke. Good luck to all of you.
EDIT: on my brothers car (nissan 240sx) he has a crank case breather filter. We put the stock hose back on and took it for a drive. There was some oil in the tube when we came back. The filter was clean as can be, so maybe proof it works? And for the record, the car has 145,xxx miles on it and burns oil at all times. |
Well, considering my dipstick blew out on the way to install Newbsauce's turbo last Monday (fiddleing with firewall and wires) and I got oil EVERYWHERE, plus the oil already in the intake......

I started burning oil resently as well. It all started on the track when my pcv valve failed. This lead to large amounts of oil being plumbed into my intake. I got a replacement that evening, however the smoking has yet to cease completely. It will dump a little blue/white smoke when I go WOT and when I let off, as well as smoke a tiny bit out the exhaust and around the turbo at idle.
I cleaned out my IC and gave it a treatment of Seafoam, so it's worse a idle at the moment (maybe 45mins of idle is all I've done so far). I'm hoping the current smoke (more whiter) is the remainder of the gunk burning off. (Catch can on it's way as well just incase it is blow-by) If that doesn't cure it, I'm going to look into the drain line (I have a restrictor). If that doesn't cure it I'm going to be running a compression check and leakdown test. It could be the rings. If those look good it may be the new test pipe. This might be causing a low backpressure condition thats allowing oil past the seals of the turbo. If just replacing that (doing it anyways soon) doesn't cure it, I'm looking at a rebuild. On a lighter note, wideband, gauge, and EBC installed. With this all said I think I've concluded that I need to do a rebuild for my poor little turbo. I let it idle and run untill the white smoke from the seafoam subsided and I was back with blue smoke at idle. I removed the drain line and made sure it wasn't clogged, I could blow through it without effort. While idling I removed the breather line and tried sucking, making sure there was no restriction in that line. No change. I swapped lines with a larger ID and this line did not have the OEM restirctor in the line. Again no change. Blowing slightly into the breather line worsened the condition...:mad: With this said and by visually seeing slight leakage between the CHRA and turbine housing I've concluded I need a rebuild. I'm blaming the cause on the combination of track and failed pcv valve. I might have starved the turbo for oil and got it hotter than it should have? Anyways, not that big of a deal since, just a waste of time. Again on a lighter note, I love my EBC and wideband |

Drftem, did you figure it out yet? An update would be nice for future oil burners.
An update on my system; I did my rebuild and everything was good and dandy. But I noticed on boost it would smell like burning oil. I couldn't visually see any leaks, but I had a quick puff of smoke out the back out the car. The only change I had really made was installing a catch can. So I ran some pressure into it and it leaked like a maniac. So my crankcase was getting little to no vacuum. I plumbed it normally and the problem was cured. This goes to show how vital crankcase ventilation can be. Sorry Dan, I think I'm still going. |
