Well you could have a blown head gasket,cracked head or block, or a combination of the above. Though I would go with the head gasket or cracked head first. You can remove the heads and have them checked if the come back clean and you could see breaks or cracks in the gasket then that's prob. your problem, if they are ok then you will have to have your block checked.. If you aren't able to do this yourself then ask around to friends and coworkers and get recommedations for good mechanics. Basically check your cost on a swap out motor and the actual repairs and make your decision..
Check the heads first. It would probably be cheaper then a complete engine swap.
It may be an intake gasket leak. Head or intake gaskes are still less than a motor.
That 3.4 GM engine is famous for losing upper and lower intake manifold gaskets. I learned it the hard way. good luck
Yes, if the radiator is clogged and the engine overheats. The main cause of head gasket failure is the engine overheating.
To change the oil pan gasket u need to raise the engine about a foot in order to get to the oil pan .
white smoke blown head gasket that's for sure..........................................................
if the engine is smoking and overheating the head gasket is blown or you popped a freeze plug
A faulty gasket, overheating of the engine or old age. Or, a combination of any of these causes.
You will more then likely have to pull the engine OUT to do that.
Overheating an engine can cause the engine to see up resulting in a complete engine failure. Overheating the engine can cause the head gasket to fail.
The most common cause is the engine overheating.
you don't have to but it is tight in there.
Loss of coolant with no apparent leak, white smoke from the exhaust especially at start up, a white foamy substance on the underside of the oil fill cap, oil level overfull, engine overheating, and possible engine miss.
The engine overheating, or a faulty gasket, or problems with hot spots in the engine.
The main cause of a blown head gasket is engine overheating. Of course it can be a manufacturing defect but that is not common.
