Well i was on the highway yesterday and i floored it in 3rd and 4th gear and i smelled oil and smoke came in the care and out my exhaust (white smoke), but then i let off and it didnt smoke anymore. I pulled over and there is oil on my firewall and around the back of my engine, i have no leak from the line to the turbo and there was no oil near the turbo, it was close to the back. I checked the oil sender and oil the block and it was tight and not leaking, but there was oil on my breather that i have on the pvc on the valve cover. Why is there oil blasting at out of the breather when at high speeds and wot. Please help, i am getting tired of this car, i knew i should of went with the kit instead of custom.

Too much crankcase pressure. Could be bad rings. Do a compression test. Do you still have your PCV valve? If so, it could have just gotten stuck so you didn't have enough crankcase ventilation.

I was also thinking something like that, but i dont know to much about it, thanks for replying, i am getting my engine built by the end of this month, so hopefully it will last til then.
