I never noticed it before (because I do not drive the car much) But my 05 V has been burning oil sense the H/C install about 1 qt every 3000 mi? Is that normal the car has 24K miles and about 7K with the H/C

Did it use any before the hc? Don't alot of lsx engines use oil? I thing it has something to do with a piston ring.

Also, is there any oil in the antifreeze or vise versa? Might have pinched a gasket.

Without a baseline consumption record for comparison's sake, it's hard to say, although depending on the heads (and porting done to them) you are more than likely pulling oil in through the rocker arm mounting bolt holes or through poorly sealing valve guide seals (or both).

Porting (on a cathedral port head) generally exposes the bolt hole to the intake port and if not properly sealed, oil will pass through to the combustion chamber.

Leaking valve guide seals are either damaged during their installation or are of inferior quality (read: cheap) .

3000 miles is not very bad oil consumption though, especially if you do a search on what has happened to other folk's cars after a mod.
