I have been fighting a coolant loss on my 2000 V70AWD now for months. It was throwing a #2 missfire code and an O2 code. I did a compression check first and they all were at 150 or so pounds. I would then top off the coolant. I replaced all the coils, more for preventive than problem. I still have the same problem, however it is now worse. Last week it started using a half a gallon of coollant per 70 mile trip. My headgasket is leaking into number two cylinder. Merry Christmas.



Check the #3 plug against the #5 plug, See if the soot on the plug is different. Nice and clean verses a little soot results in a little water getting in the combustion chamber and cleaning things up.



I am tempted to try a mechanic in a can to see if the headgasket stop leak stuff really works. I am just afraid of all the other stuff it might plug up.
