As i noted in the WDYDTYCT? thread, i had a thermostat lock shut and my commander overheated pretty hard. (was driving on highway when CEL and temp were pegged).. Now I get misfires on cyl #2 and the coolant is bubbling consistently. I am going to do a compression check to see what's really going on. Thinking at a minimum its a head gasket and more likely dropped a valve seat or warped a head. Anyone do a recent rebuild have any thoughts on a budget? i'd probably do reman'd heads since i am sitting at 214k miles.. and if I am doing all that i figure i should go ahead and pullthe lump all the way out and do bearings and piston rings to freshen everything up... and if i pull the motor why not have the trans freshened up... this is getting expensive in my mind... anyone have any idea how often the block is damaged in overheating events like this?
