Grey Smoke On Acceleration


Recommended Posts

I am gettting huge streams of grey smoke after high speed cornering through the hills. Smoke only comes out when I hit the accelerator. After 2-3 accelerations back on straight flatland smoke will not come back again until next time I go through the same corners.

Replaced the AOS, cleaned the throttle body, MAF, and Y tube 450 miles ago. No CEL, Autozone didn't pull any codes. No smoke otherwise. I smell burning oil each time after driving. I do have a very slow RMS leak.

Stock, 70K miles, all service up to date and never abused.

Any ideas?

Thanks.

BTW Mike, Thanks for your write up, it helped me a lot!

Hmm... Interesting thought. I did do it late night after putting the kids to bed so maybe I missed something. It seems tight but I'll have to lift it to check the mounting bolts.

Two of my hose clips broke when I was taking them off. One going to the TB and the one coming from the middle of the AOS to (I believe?) the engine block-it goes under the manifold and dissappears. That one I wrap-tied and is not leaking oil but perhaps air is getting in there?

For the 'Y Tube' I have a new one on order but the clamp was still mostly functional.

I also used a hose clamp for the bellows hose but will maybe put the original clamp back on.

Does this like a logical reason for the problem I am having?

Do you know where that middle hose ends up and how difficult it is to replace?
