"rillweid - Now with more TRD and less TDI" (rillweid)

I filmed this !!!error: Indecipherable SUB-paragraph formatting!!! a few weeks ago of my truck. It burns something(gas/oil?) on startup. This only happens on cold starts, and I think is more pronounced when it’s cold outside. Doesn’t appear to happen during normal driving. Oil level doesn’t appear to be decreasing, so I think it may be running rich.

Haven’t pulled any codes to see if something is stored, but no CEL or any other lights are present.

Went to the dealer twice right before video(once for an oil change), so if something catastrophic is wrong I hope they would’ve noticed it. Also 49k miles so unlikely to be bad rings.

I suspect out of spec 02 senor might be causing this. I’ve heard Tacomas run closed loop on startup so this may just be normal operation.

Any advice/suggestions? Any other taco owners out there also have this problem?

Video may or may not work as I had to upload to Google Drive since no Kinja video function exists. Let me know if there is a better way to do this.

Oil leaking down the valve stems after it’s sat or similar would be my guess sadly. Probably not very much however

The initial light blue puff says oil. The white vapor afterward looks like water to me (can’t smell it so dunno for sure) which would be normal.

Guessing Echo51 is probably right.

Exactly. Valve stem guides.

Do you think it’s the guides or seals?

Have you tried an Italian tune up?

Valve seals most likely
