Overheating OM617
What have you done to the cooling system/engine lately? Sounds like your headgasket might have failed. What color is the smoke coming out the tailpipe? Black or white?


Good luck with the 300 in the meantime.

I'd start with simple things though like verify the water pump is working. Make sure the t-stat is not stuck.
Okay, coolant system would not even make pressure. Just poured coolant into the cylinder(s). Have removed the valve cover, and are going to adjust valves before we retry compression test. Valves are all WAY to tight and compression was VERY low. I'll keep you guys updated!
