In relation to oil consumption, is it the valve guides or seals that go bad and possibly need to be replaced? I havent done the leakdown yet but plan to very soon and Im *hoping* this is where the problem lies. Compression numbers look good.

 

Probably rings, and not anything valve related if it's typical of most other ITRs. Mine compression checks fine too, but gulps around 2-3 quarts per oil change. There was an analysis and explanation of this problem several months ago in this forum.

One of the signs was to check you oil say a few hundred miles after an oil change. It would normally look like honey or still golden brown, but with failing rings it should get dark much quicker.

 

Youre referring to the oil rings and not the compression rings, right?
