I had the cambelt done on my car and the mechanic left a note saying that he'd noticed a small oil leak from the turbo. I was under the impression that the 1.6 ecoboost is water cooled? So does this mean an oil leak is likely to be an internal seal and the turbo is going to need refurbished?

He'd closed by the time I picked it up and is now closed for the forseeable future, so I can't call him to check. So thought I'd ask on here.

I have a friend with a full inspection pit, so I can go and take a proper look once we're allowed to socialise again, would just help to know what I'm looking for.

 

Thanks 🙂

The turbocharger is water cooled but the bearings are lubricated by engine oil. Because of this the turbocharger has an oil feed line and an oil return line to the engine block.

You have to determine first whether there is an external leak caused by either the oil lines or a connection between the oil line and the engine block/turbocharger or if there is an internal leak caused by a defective seal.

So finding a leak on the oil feed or return is I assume what I'm hoping for, then it's just a simple case of replacing an o-ring or seal on the connection? 

I imagine stripping a turbo is way beyond my technical expertise though, so more than that and it'll have to be a garage job
