just do another dry test, make sure its 100% warmed up (doesnt take that long to do ) but 2 capfuls for the wet? wat size cap? all u need is a couple of drops...trust me...for fun i put uhh lets say 20drops from those little oil dripper things and now the car has a rough idle (in a shop car in my rop class) and needs new spark plugs...o and oil was leaking onto the head...so yea ONLY do 2 drops. and i think he meant valves instead of cylinder head...
