90 awd 5 speed n/a with 130,000 miles. Was sitting for two years until now.
Standing in front of car, looking at engine. (I performed the test correctly)
Dry-
120 140
160 180
Wet-
150 150
180 190
I just bought the car so I don't know if it burns fluid. It does leak oil from like every seal in the engine bay.
The numbers are bizarre and make me worried. What do you guys think?

Re: Bad compression results! :(
Did you have the throttle open while testing and was the engine hot or cold?

Engine was operating temp, I was in wot yes.

I would suggest changing the oil and run it for a bit and retest it. With it sitting for two years could have some light surface rust on the valve surface giving your readings. Also marvel mystery oil in the gas wouldn't hurt, it will help lube the valves on the top end.

I actually did the oil change before the test and have since purchased MMM and put it in my tank and a little but in my oil. I hope it will get better
