Actually it sounds like it's comming from the cylinder head. after the car warmed up last night it stopped once i gotr it on the freeway and above 3000rpms ( i really wanted a h22
) and it never came back this morning. i tested to see if one of the cylinders are missfireing, or has any knoks but none of them knock. tomorrow i'll have the valves adjusted, but i need to get those adjuster screws first. they are only 2.50 a piece at most. i just need to know the specs for the valve adjutament.
