We are working on a 2000 Chevrolet Malibu that overheated and now will not start. The big problem is that you smell a strong presence of gas in the radiator overflow tank. There is no coolant in the oil. The compresion is about 125lb in all cylinders except one that is 100lb. Could the problem be a blown head gasket?? The car has 125000 miles on it.

Overheat, low compression with one out of line completely, odor of fuel in cooling system overflow. Pretty damning for head gasket which is sealing everything in every way. They don't have to fail to put coolant in oil. You can probably see vapor bubbles in the recovery tank just cranking this.
Do testing before you jump into this and would bet head gasket, cracks, warpage possible so would have to check all,

There is really no way for that to happen without someone physically pouring it into the coolant.You can get combustion (exhaust) gasses as Tom suggested but that smells nothing like gasoline.

Thanks
We are going to do some more testing and probably pull the heads.

Just some last thoughts before you tear into this........
If really fuel in coolant about all I can think of is a badly leaking injector (probably cyl with lowest compression) AND a substantial gasket leak into cooling system at the same time?! If oil level is oddly too full also this could be trouble on top of trouble.
Careful what you spend until basics test OK on this engine so you don't find out there's a disaster that would make reasonable repairs too much for that one if it gets that far.
Duh - careful if raw fuel around and be ready. Good luck,

We will drain the antifreeze, fill with water , and get it to start before we think about tearing it apart.
Thanks
