Turbo issues

[poul]

Does anyone have trouble with leaky oil feed to their turbo also sliding intercooler pipes to the turbo under boost

[motoz]

Yes mate probably everyone at some stage. Usually caused by the crank case ventilation plumbing oil mist back into the intake pre turbo.
The factory hose clamps are as weak as piss and should be replaced with something stronger.

You can add an oil catch can to help. Remove the inlet pipe and give it a good clean then beef up the clamps.
