Blue smoke
This has been happening off and on, and is now getting more "on".
My S2000 has always had high oil consumption since it was new - about 1 quart for 1000-1500 miles, sometimes a bit higher. Yeah, really.
Lately I have noticed the car lets out a single puff of blue smoke when the engine is started. It does not do this all the time, and usually does it when the car has been sitting for a couple of hours and the engine is still somewhat warm.
No smoking during idle or normal driving - I haven't noticed it during acceleration or downshifting either.
Other info:
MY2003, 48K miles. I've been using Mobile 1 since about 9K miles and there are no mods. Blackstone oil tests showed nothing unusual - even with the high consumption, but it's been quite a few miles (20K) since the last Blackstone test.

sounds like a valve problem to me
The big problem is that it's embarrassing as all hell when the car does this in public.
Fixing it isn't a cheap repair either.

You can do the the valve stem seals without having to remove the head but it is involved and requires shop equipment. The guides could be (most likely are) why the seals are leaking. Bank on a valve job but the seals can be done as a stop gap.

Yep, this resembles de typical valve-guide issue. Some clouds of smoke alone, not "always smoking".
It is not very dangerous for the engine, but soon or later you will have to replace that guides.

MY 03 RED is also doing this from time to time. how would I tell the dealer or mechanic what to fix?
im buring about 3-4 quarts per 3000 miles.
to clarify, valve stem seal and valve guide is the same thing correct?
