In my other post I mention my experience with a failed Thermostat Housing on my 99 XJ8 4.0 V-8. After replacing the thermostat housing and the water pump, car was running rough with a number of codes.
One thread on the subject of overheating said that you can experience valve seats coming loose and or possible head gasket leaks.
I don't see evidence of any coolant on the engine oil dipstick.
I ran a compression test.Left front cold was 125 psi, All others read between 190 and 200 psi. I pulled fuse #7 in the trunk fuse box so that the fuel pump would not operate. I turned over the engine while listening for some out of ordinary sound, but did not hear anything different than the other cylinders.
I want to check the torque for the head bolts. Anyone able to provide the torquing pattern and the torque value? Is there something else that I should check?
