If the thermostat was not installed correctly, the housing can crack but it would leak engine coolant not oil.
It is possible but it depends on where the crack is. If the crack is from the combustion chamber out, such as through a coolant passage it can also suck in coolant/antifreeze and loose compression.
If the radiator is cracked then the vehicle has ran dry on coolant. This would cause the radiator to crack if there wasn't any coolant.
Check the radiator coolant level! When it is low, and RPMs decrease at low speeds or idle, the coolant isn't being circulated through the entire cooling system, such as the heater core! Be sure the engine is cool before opening the radiator cap and adding coolant! NEVER add coolant to a hot engine because it will crack the block or cause the head gasket to blow!
No It would not unless beside that plenum on your block is a crack in your heads and your leaking coolant or even leaking internally check head gaskets
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.
crack in engine block or head, so the coolant leaks through crack into oil. very common problems with engine to get cracks, maybe a design flaw or when you ran without coolant, it may overstress engine!
a crack or a hole in the tank. or hose for that matter
Yes, a cracked cylinder head can cause bubbles in the coolant. This occurs because the crack may allow combustion gases to escape into the coolant system, leading to the formation of bubbles. Additionally, the crack can create a coolant leak, further disrupting the cooling system's efficiency. It's important to address this issue promptly to prevent engine overheating and further damage.
A crack near or on the thermostat housing can cause a coolant leak in a 1996 Grand Marquis. The thermostat housing is located near the manifold on this vehicle.
The temperature contrasts would cause differential expansion of the bottle which, being brittle, would cause the glass to crack.
A faulty thermostat in a 2001 BMW 325CI can cause a coolant leak. The coolant may be leaking out a crack in the thermostat or through a warped edge. In some cases the problem may be just a bad gasket and not actually a problem with the thermostat at all.
