Chas H,

Thanks for the information.

CamelotShadow,

Cylinder #4 had the wet plug

Only the Cam/Valve cover gaskets were replaced when I did the timing chain. Head gasket wasn't removed because I didn't replace the lower guides, just top ones.

Why or What would cause the coolant temperature to go from 100 to 130 degrees in less then a minute while driving 45 mph with outside air temp of 70 degrees?

Vehicle was runnung good before engine got hot and started knocking.

Thanks,

Justin
