Can adding 1 quart oil too much cause the oil pressure to drop and the engine to knock?
Adding too much oil will cause your engine to burn off the excessive oil which causes a lot of carbon buildup in your engine and a lot of blue smoke out your tailpipe. If the oil level is high enough, it can contact the crankshaft and foam up. If the oil foams it can damage the engine.
As you did not say which vehicle this can only be a general answer Unlikely that a faulty coil would cause an engine to knock. Very possible it would cause bucking, if the coil is failing there would be a lack of spark. This would cause bucking/missfire, which may cause the engine to shake on it's mountings possibly causing a knock from contact with the vehicle frame.
Will burning regular gasoline in a 3800 series ii supercharged engine cause the check engine soon light to go on?
Knock in the engine that comes and goes the oil pressure is on the low side and you had lots of recent repairs around the engine are you losing your engine?
Any way to temporarily repair plug for Knock sensor on 1993 Chevy blazer k1500 to get it to start to get it home?
In SI engine knock occur due to spontaneous ignition of end gases , as propagating flame compresses the mixture causes high temp & pressure reaction take place in end gases that burns rapidly with high pressure peak called knock. Where as in CI engine knocking or detonation occur due autoignition fuel & air not mixed homogeneous prior to combustion. pressure peaks of knock come before Top Dead Center(TDC) in CI engine where as in SI…
No, knocking in an engine is normally more serious than a gasket leak. Depending on how heavy the knock sound is it could be the Big Ends bearings need changing or it if its fainter than that it could be the timing is out. Either way it can cause real damage to the engine and should be repaired as quickly as possible. Have seen exhaust manifold gasket leaks that are described as a 'knock' by…
Your Subaru Impreza WRX 1995 has started knocking badly l think it might be the knock sensor but the engine management light is staying off?
What's your oil pressure like? I'm not asking how much oil you have... is your oil pump able to provide enough oil volume and pressure to allow the engine to run properly? If not, the engine will knock and tear itself apart. Oil pressure will reduce if the engine bearings are worn and the oil leaks out so fast that the oil pump can't keep up.
A knock sensor is a sensor inside an engine that detects detonation of fuel prior to the spark plug igniting the full during the cycles of the engines. Detonation at the wrong time can cause significant harm to an engine since it will cause the piston where the detonation occurred to be pushed down at the incorrect time. This can result in a catastrophic breakdown of the whole engine. A knock sensor monitors irregular detonation…
