Blue smoke help!

[speed_nut_yn]

Im getting blue smoke occasionally from my exhaust (bora tdi 130), It is very intermittent and only seems to happen when the car has been running for a while so is the engine is hot, i can also sometimes see sparks / ember from the exhaust when revving, when it is smoking you can really smell burning oil quite strongly. The car drives fine and pulls perfectly normal, even when it is smoking, and most of the time it doesnt smoke at all, so am very confused as to what could be causing this?

Any ideas?


Thanks

Google it


Could be many things, turbo oil seals, valve stem seals likely

Also noticed there is drops of oil on the floor under the drivers side corner of the front bumper, i presume this is coming from the intercooler somewhere? Could this be part of the issue?

I doubt you'll have oil leaking from the intercooler as the intercooler's purpose is to cool compressed air.

If by some chance you do have oil in the intercooler, that's abit of a problem. It may be due to simply over-filling the car with oil which could cause oil to get into the airtake via the crank but it may also be down to a knackered turbo.

It's difficult to diagnose over the internet as it could be anything such as oil pipes, oil cooler, turbo, valve stem seals, etc..

Get the car to a VAG specialist.
