Anyone had trouble with loss of compression on cylinder #4?
35
'02 with 57k miles. Has an occasional pinging sound like spark knock under acceleration. Octane boost did not help. A compression check revealed 210 psi on cyls 1-3 and 100 psi on cyl 4! Loss of some power is evident.
It has also been steadily consuming more oil. Now, I need to put in about 1.5 quarts between 3000 mile changes.
