Low compression in 3 cylinders. 125, 90, & 90. Any idea's on most likely causes? Mechanic thinks for best case scenario a few valves are burnt (yes, he's trust worthy) but it could be something worse of course.
W/ my limited engine knowledge, I don't know of a way to tell if its the valves or something else. Is there any way to tell with some degree of certainty without doing a full r&r? Asking so I can to determine the cost of this repair.
Dang I wish I knew this was gonna happen before I just had my timing belt done last month since they're gonna have to undo all that work!
