Apparently.... the garage it’s been at said that the oil pump hasn’t been functioning properly. And I've had the beast down VW/AUDI on the computer prior to the oil pump issues. And it had a air leak... that got fixed, and they reckon since the pressure within the engine has got back to what its ment to be its made the oil pump pull a load of junk through into the engine the geezer reckons it needs a top end rebuild... cam bearings etc all burnt out as far as I know the turbo is fine.. im getting the final verdict on it today. As he’s basically gonna strip it all down and see what is actually needed.. 500squids isn't a bad price for a engine.
