Anyone had trouble with loss of compression on cylinder #4?


Asked by May 25, 2007 at 03:40 PM about the 2002 Chevrolet Prizm

Question type: Maintenance & Repair

'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.
