it sounds like the exhaust was blowing from what can be described as the noise came from the bottom right slightly, jacked the car up checked the exhaust absolutely fine, what i did notice was the turbo was caked in oil and i mean a lot, the blow off valve is spitting oil out and the car smells of warm oil at high revs in 4th and 5th if giving it some, i checked my engine oil and it had all gone, so i topped it up and all seems okay getting a compression test done on tuesday just to be safe, the engine has only done 115k killometres so pretty low mileage and has standard top mount, am i right in thinking oil seals etc and oil feed have gone on the turbo because i get slight juddering hesitation then it kicks in like lag seriously paranoid about the engine, no blue smoke or anything and it still drives fine, boosts fine just really really weird, any help much appreciated, like i said compression test tuesday and gonna get it a BIG once over from a know it all mechanic friend so ill report back but in the mean time any help please and sorry for the essay
