A cracked block or a leak in the head gasket of the 1995 Impala SS can be caused by overheating the motor or even by drastic temperature changes. For example, adding cold water to the motor when an engine is hot can cause the block to crack. Gaskets sometimes leak when worn or when exposed to extreme temperatures.Ê
Usually the expansion of the block or different rates between block & heads if composed of different materials makes it blow out when car overheats (most common cause)
Most likely a failed head gasket or a cracked or warped head. Less likely but possible is a crack in the block.
no
Also a cracked block or head, the heads on a 2.2L often crack when the head gasket fails in my experience.
first suggestion would be the head gasket which Montana's are notorious for having problems with, followed closely by a crack in your cylinder head or engine block
Not directly, but it can crack or blow your head gasket. (Which will cause white smoke) Happened to me =(
If you are sure that it did not freeze and crack the block, Then the intake manifold gasket is leaking. That is a common problem with the vortec Chevy engines. You need to replace the gasket with a factory Chevy gasket from the dealer.
the cylinder head gasket needs to be checked you have a blown head gasket or a crack in your engine block. this is causing water to leak into your cylinders and evaorate in the heat blowing lots of steam out of your exhaust. blown gasket = new gasket cracked block = new engine and stop over revving your engine. shift BEFORE redline and if you have, DO NOT bounce the rev limiter. if you engine spins to fast, it gets to hot. if it gets to hot, you blow seals, break stuff, or crack your block. Did you perhaps not have enough antifreeze in the system during a cold spell, allowing the coolant to freeze, expand and crack the block?
When an engine overheats the head or block or both can crack or the head and/or block can warp or you can be lucky and none of the above might happen. If the head warps your head gasket will fail. If the head and/or block crack you will need to find replacments. If the block warps you will need to bore the cylinders and align bore the lower end. None of the above are cheap.
Probably coolant in the oil from a blown head gasket which might also cause excessive steam from the tailpipe and hard starting. The coolant also could get into the oil through a crack in the engine block.
blown head gasket, cracked cylinder head, crack in the cylinder block
Most likely is that a gasket or seal has blown, or a crack in the engine block is letting water in from the cooling system.
