Polo 2009 1.9tdi oil in boost pipes

[Morgs]

Hi guys my polo 1.9tdi, has a huge amount of oil in the boost pipes. There's to many stories and hear say, so am asking you guys what can it be, I don't want to start working on something that ain't going to be a solution.

It's normal to find some oil in the boost pipes and intercooler.

If excessive, it either comes down to a faulty turbo that's bypassing from leaky seals, or excessive blow by from the engine / heavy vacuum from a tuned engine or big turbo.

Since these tappet covers have a sealed breather its difficult to tell what's going on inside. I have seen engines especially the ones with big turbos pull oil into the induction pipe. Only way around that is to either get a new tapper cover, fit a proper oil catch can or dump the breather to atmosphere.

Will work around it and keep you posted

Hi all
On the subject of boost pipes, is there a recommended replacement for the 90 deg bend boost pipe that comes off the egr on the polo 1.9tdi motor?

Direct replacement (maybe goldwagen keeps them) or race pipe and silicone joiner.

Try Pro-Auto Rubber (https://parmegastore.com/), they sell silicone pipes, joints etc.
