i have read a few posts, and yes the H22's burn oil and run rich, but here is my situation,
1. 1100km (690m) since oil change,
2. daily driver, keep it under 3000-3500rpm using the SS mode (actually saves on gas, i short shift alot, so no abuse on the tranny)
3. no oil leaks
4. exhaust tips/bumper clean, no sud build up.
over 1/2- 3/4 oil gone
how have i lost so much oil in 1100km!!! driving it under normal conditions without any visible signs!
the only reason i noticed is cause my vtec didn't engage when i had to merge on the highway last night. I DONT VTEC alot
That's pretty heavy oil consumption. Are you sure you had a full crank-case at the beginning of the 1000km? Before doing anything rash, run another consumption test.
That's pretty heavy consumption still. (1qt in 621 miles) When I was on my old motor and driving it pretty hard I had gone through a quart in 500miles (a lot of vtec). However, I was away at school w/o my car when the dealer wanted to do an oil consumption test, so my mother drove my car and didn't burn a drop of oil, but professed that she never once touched vtec. Maybe the dealer lied, I dunno, but it would say there was a clear relationship to time in vtec and oil consumption. The dealer also said that burning a quart or less in 800 miles was considered acceptable, which I think is ridiculous.
They recommended I run 10-w30 to slow the consumption. I forget how effective this was, but it didn't hurt anything to my recollection. If your pcv line is clean, there's a good chance your oil control rings are worn.
the oil control rings are the lower-most rings on each piston. They 'sweep' the pistons walls clean of oil so that oil doesn't burn-off with the combustion chamber combusts.
I know what they are. Which stroke are you saying that it sucks the oil up in? Certainly not the compression stroke.
Could it be...the intake stroke?

The oil control rings clean the walls of oil everytime the piston travels towards BDC. Has nothing to do with the combustion cycle. That's most likely your problem if you don't have any oil leaks.

well yeah it does. Each stroke is associated with a movement of the piston, up or down, hence the term 'stroke'. Two of the strokes involve the downward movement of the piston, two upward.
Yea, but the cycle itself itself is arbitrary relative to the oil control rings' function. Everytime the pistons move towards BDC, they scrape the oil of the walls.
If you're really hung up on relating that to the combustion cycle, that's fine. Doesn't change anything.
