Usually some carbon deposits are left clinging to the combustion chamber surfaces, these deposits are red hot and ignite fuel/air mixture after the ignition is turned off. This could be caused by letting the vehicle idle excessivly long or only using it for short low speed trips. some times it may be caused by too rich of a fuel/air mixture. If it is carburated, if the idle is too fast it will cause it to diesel.
it is not a cracked engine block it is just a loose block
clogged thermostat
Flushing sludge from your engine is not a very smart thing to do. Almost every automotive technician will agree with that. Flushing out an engine causes all the sludge to drain down into the oil pan. Which in turn tends to plug up the oil pick up and causes engine damage.
There is no such engine as a Cummins 2500 Diesel.
Antifreeze in the oil of any engine means there is a crack in the head gasket, or worse, in the block.
There are four causes of the engine failure. The four causes of the engine failure includes engine overheating, lubrication problems, misassembly , and detonation.
No gas in the engine
engine burning oil
what causes my corola dx wagon with a 5e engine to ping
The engine causes thrust, it moves the aircraft.
Your question is sort of backwards, perhaps you meant what causes engine failure? Engine failure causes...the engine to fail. If someone told me their engine failed I would take it to mean that it stopped running, or wouldn't start.
Excessive revving of an engine causes overpressure in the crankcase. It causes unhealthy expansion in the pistons and the valves.
Bad piston rings. Get new engine.
this is usually engine coolant leaking in
Bad wire
backfiring.
The engine is overheating.
