the most common cause would be a stuck closed thermostat.
The antifreeze level in the overflow tank can drop due to several reasons, including coolant leaks in the system, evaporation over time, or a malfunctioning radiator cap that allows coolant to escape. Additionally, if the engine is overheating, it can cause the coolant to expand and push some out of the overflow. Regularly checking and maintaining the coolant level is essential to prevent engine overheating and damage.
Most common cause of surging is a dirty/clogged air filter.
Yes, a backfire can cause a bent push rod. When an engine backfires, it creates a sudden and violent explosion in the intake or exhaust system, which can generate excessive pressure. This pressure can lead to a rapid movement of engine components, potentially causing the push rods to bend if they are subjected to forces beyond their design limits. Additionally, other factors like misadjusted valves or improper timing can exacerbate the risk of bending a push rod during a backfire.
The more you push on the accelerator the more you increase the fuel/air mixture to the engine which will cause the engine to turn more RPMs, thus propelling the vehicle at a faster speed.
NO it will not. Over revving engine, Rocker are adjusted to tight, Bad lifter. These are some common causes of that.
the oil pump in the oil pan is bad, or worn bad enough that it no longer can push enough oil
Excessive spark knock (aka, pre-ignition, pinging) can cause serious damage to the engine if not corrected.
it depends how hard you push
That orange Dex Cool crap GM likes to push.
It is to be found in your imagination since push mowers have no engines.
A bent push rod can be caused by several factors, including excessive engine wear, improper installation, or incorrect valve timing. Over-revving the engine can also lead to a push rod bending due to increased stress on the components. Additionally, issues such as a broken valve spring or a stuck valve can create abnormal forces that result in a bent push rod. Regular maintenance and inspection can help prevent these issues.
On an overhead cam engine, the lobes on the cam push the rocker arms which push the valves open.
