dude that sux that your h22 is coughing up blood....um the engine normally burns oil when driving and you can see it from another car when vtec is engaged, its like a black smoke, you have to check your oil once a week like i do because that engine loves to burn oil...also how many miles are on the engine and your piston rings could be letting to much oil into the combustion chamber...use 20-50 weight in the summer its a heavier oil so maybe it would stay in your crankcase and not enter through your pistons.

Cracked cylinder head propably...
