Spent the night in the garage getting to know this one. Pulled all the spark plugs and had 170-190 psi per cylinder with the exception of cylinder #3. #3 had 0 psi. Yep, 0. I was able to look in the cylinder and see the piston moving in and out, but obviously no real diagnosis while the whole thing is still in the car. I'm guessing this is a valve problem. Any thoughts on what kind of valve failure is common with these motors?
