Thanks for the reply! Yep, having the head checked is what I'm gonna do next. I noticed you said you got one with a blown headgasket due to overheating. I'm just wondering what could have caused this to happen as the car wasn't overheated. Either that, or the gauge is way off. I'll DEFINITELY be putting other gauges in there, but I can't for the life of me figure out how the head gasket blew.
Ohh, I forgot to mention, when I pulled out the plugs to do the compression check, all the wells were dry and clean. The plugs however, were covered in black carbon and I just replaced them yesterday. On the number 4 cylinder (which read 210) however, there was oil on the bottom of the plug...now I'm not sure whether that could be residual oil that originally fell down the cylinder from when it was full of oil or could be a bad ring, but I'm assuming that's why I had a higher number on #4.
BTW, IF the temp gauge is correct (when I start it, its at the very bottom and gradually goes to the middle but no higher) then why isn't the car overheating since it has a blown head gasket??? I mean, its gotta be a bad leak if I have 0 compression and MASSIVE amount of white smoke out the back. Could it be that's where my problem really came from??? The car is actually overheating, but the gauge is broke?
