my accord has been overheating and you can see bubbling in the coolant resivoir. i just did a cold compression test that was 210, 180, 200, 205, #3 being the 180. do u guys think this is a headgasket problem? i dont see what else it could be..already searched, just makin sure..any input would be appreciated...

 

thermostat? bad coolant? look into those..headgasket symptoms are like leaking oil...and werid smoke out the exhuast i think correct me if im wrong

 

overheating cause blow head gasket -

but for now check your T-Stat, coolant, etc...make sure your water pump is working. If you have air pockets in your cooling system -- yep it will cause over heat and blow your head gasket...even crack your Head or Block....

I had this nightmare - end up replacing the engine.
