Timing chain
« on: March 22, 2009, 06:12:59 PM »
Anyway to check the timing chain without removing anything? jeep idles but doesnt runs well under load i have replaced tps, cps, plugs, wires, cap, rotor, fuel filter, fuel pump, fuel injector, cat converter,flywheel, distributor, and ecu. It still doesnt run right. stalls out and has no power compression is around 130! I dunno let me know what you guys think!

you would be able to tell if it is excessive or not.  i believe a little bit is okay.

What about the marks and where they are supose to line up? I am not sure seems like everything is good though. What are signs that it may have jumped?
