If you have coolant in the oil, it will cause the rod and main bearings to fail.
In most cases yes it will. The coolant will mix with the oil and this will immediately cause damage to engine bearings and rings. STOP driving any car with a blown head gasket. You must have this repaired immediately or you will destroy the engine.
You need oil in the compressor just as you need oil in your engine. If there is no oil, it will lock up and seize internally. yes it can cause damage to the bearings in the compressor. The unit has oil in it to lube
The imbalance will cause vibrations in the crankshaft that will wear out the main bearings and the engine will lose oil pressure.
It gets dirty with carbon from the combustion process and blow, all of which would cause damage to the bearings and engine if left to build up.
very unlikly. How long was the vehicle run for with the flusing agent in oil pan because this can cause damage, not to head gasket but to rings,cylinder walls,rod bearings etc. now was this engine or coolant flush.
As long as the engine is at full operating temperature and you do not rev it beyond the red line, you more than likely will do no damage, but it is still not a good idea. Revving a cold engine will do damage for sure. Revving the engine can cause a sudden drop in oil pressure, cause the engine to over heat and it doesn't help the main crankshaft bearings any good as they and meant to be revved under a load(in gear).
No - a small amount will not damage the engine, though may cause it to run badly. However, a larger amount can cause serious damage, and the tank and engine should be drained.
On an interference engine the pistons can hit the valves. That will cause severe internal engine damage.
Bird strikes to an aircraft rarely cause human casualties, but CAN cause damage to an airplane or an accident. A direct bird strike to the jet engine of an airplane during take off and landing can be particularly serious.
Severely over heating the engine may have damaged the main and rod bearings.
No, but it can cause severe engine damage if you keep running the engine.
