Non-Honda question, but I'm hoping you someone with FI experience can at least shed some light on a problem.

My Wife has a Volvo V40, 1.9L turbo, 163,000 miles. This is the only turbo vehicle I've ever owned.

I was doing service on it over the weekend and noticed that the compressor housing had a film of oil on the outside. Looking closer, it appeared to be coming out of the rubber connection between the compressor and the boost pipe that runs up and over the engine. I pulled the boost pipe and found oil inside. I then pulled the rubber connection between the intercooler and intake manifold and found oil in there as well.

General google searches seem to indicate that a little oil in there is OK. Enough to leak out of the connector, or to find it's way through the IC, seems like too much to me though.

The car doesn't blow blue smoke and a very basic pressure test at the oil cap doesn't show that there's a PCV system problem. Is this likely an oil seal failure inside of the turbo itself? I believe the model is TD04L.....if that helps.

 

For that milleage, is pretty normal to see some oil inside the compressor housing and/or the boost hoses.

 

Yep. Plus, a little crankcase pressure from over time.. Pretty normal.

 

Thanks guys, much appreciated.
