my buddies maxima has been acting weird maybe a head gasket. its been sittin for a while. he has had problems so i went to check it out here is what i got. after sittin about 2 weeks since being started we started it no problem checked it out. no water leaking that i saw, but he did say he had temp problems with it. we drove it around for like 5 minutes and had it idled in his driveway for about 45 minutes and a/c on. Temp never went past half way. we shut it off and start a few times ok. it didnt seem to have the power it should so i shut it off for like the third time to check some stuff. I tried to start it up and it made like a squeaking sound and blew enormous amount of white smoke out of it and it barely started and when did it acted like it was on like 1 cylinder and stalled and wouldnt start no more. sound like a headgasket to you or maybe crack in block but i didnt see no water leak?

 

compression check it.
