i noticed my engne overheating last week and thick white smoke......compression numbers are 110 120 70 60 im guessin bad head gasket between 3 and 4 but wat would cause the first 2 cyliners to be soooo low? could it be piston rings?

 

Don't know what your problem is, but thats definitely half of what they should be at least...Hopefully some one can help you out on here, or take it to a mechanic and ask him to look at it.

Yea would bank on the head gasket being bad. Check to see of your oil is kind of milky. I would also run a leak down test and pull off the radiator cap to see if any air bubbles out. If it does then you are going to need a head gasket. Make sure you get it changed ASAP because coolant is not a good lubricator. The longer you let it go the more damage it will do to you internals (bearing, rings, ect.).
