Uh Oh, Something Is Wrong With My Engine

[matthew0786]

This is the story, two nights ago i gave my car a little hit on high boost (16-17psi on a gcg hi flow - 247rwkw) and suddenly i lost power , no boost and the car stalled. So i started the car back up again and it was idling very rough. I checked under the bonnet and there was engine oil coming out of the oil cap.

First thing i thought was the turbo and i pulled that off today and there were no visible signs of damage (no blown comp or exh wheel) and it spun ok, but im not turbo expert. I might take the turbo down to MTQ and have them check it out but then again, i could have landed a piston.

So what do you guys think it could be?? Any help would be appreciated.

well hopefully you have just popped off an intercooler pipe or similar, not sure what you mean when you say oil is coming out the oil cap though.

first check all your cooler pipes are on tight that will make it idle terrible. next thing to check is the compression either give it to a mechanic or do it yourself - and save time and start at cylinder #6.

ok, ill check the compression and let you know

i just checked the intercooler pipes and they are not loose. Now, a noob question - am i able to do a compression test while the turbo off? Also, If there is no visible signs of damage on the turbo or oil leak, can it be damaged? because now im questioning whether to take my turbo to get it inspected.

what i meant by the oil coming out of the oil cap - as in i found oil on my rocker cover when i opened the bonnet

so any ideas on what i should do at this time? take the turbo to inspection OR check compression (i dont know if the turbo has to be on or not to do one)

Check your compression ! You may of blown your head gasket and yes you have do it with the turbo on cause oil will pump out of the oil lines when its off !
