I ran a compression test on the car tonight. 1,2,4 ran about 170lbs. #3 had zero lbs. I even put some oil into the cylinder, but still got zero commpression. Does this sound like a valve problem?
Is there anyway of testing valves without removing the head? Just doing a visual it looks like the intake valve rockerarm is not coming up as high as the others. Should you be able to see a difference like that.
On another note. I am missing a sensor of some sort, that is mounted to the head above and to the right of the water pump.
The lead has only one wire and it is green.
