I compression tested my car tonight and i got really dissapointing numbers.
I let the car crank over 4 or so times before i let off. It read at 125 for all as its peak, and it wasn't able to sustain it for long, it would just drop very quickly. Then we put some oil into the spark plug hole and tried it again in cylinder 1, it hit 160 and dropped again. So is it the piston rings that are going bad? or problem with the valves....
