Title: 2007 edition 30 burning oil problems?
Post by: gttjames on 22 June 2012, 13:27

Before i go balls deep and start stripping it i was wondering if you guys had any ideas, previous problems, i have searched the boards but not found my answers.

Got an edition 30 golf mk5 2007 2 litre 230bhp

It uses a litre a month/900miles - which according to the service book is just within tolerance, but i know people who'v had these and similar cars and 1litre a month is to much it must have a fault. You can see some blue smoke when pulling away etc

Engine sounds fine, have spoke to vw dealerships and they say theres nothing common to look at. Im thinking of it could be engine internal or possibly turbo oil seals? thoughts?

blue smoke points to oil seals - is there lots or a little under full throttle?

Turbo oil seals usually manifest themselves on lift off. When the turbo boosts, the speed of the shaft usually is enough to "re-seal" any damaged seals. Once you lift off and it starts to spin down, the oil seeps through and into the exhaust.

If it's when you're on the gas, it sounds like either excessive wear on the oil control rings on the pistons, or you're having some serious blow-by in the PCV system. Try disconnecting the oil breather pipes and put a rubber glove over the end with some rape-tape. Take it a short drive (with the gloves out the way of anything super hot) and get it up to temperature. You'll know exactly how to provoke the blue smoke so drive it as normal and keep an eye out.

The other way to check the oil seals is to whip the intercooler out and tip it up. If oil runs out, the turbo is goosed. It's perfectly normal to have a thin layer of oil all over the inside of the pipework and intercooler internals.
