Main bearings on the crankshaft are bad. The reason for the noise is that when the oil gets hot it thins out, thus causing low oil pressue thru the crank bearings. This in turn doesn't push enough oil the the cam lifters. causing them to chatter.

Will a low oil level warning cause the engine to quit on a 1995 chevy caprice


It could, once the engine is running it then keeps the fuelpump running with the oil preasure switch and if the oil preasure drops it can stop the pump,but should start back up unless theres a bad fuelpump relay,

Low oil pressure light is on on 2000 lexus rx300. Doesn't need oil or an oil change. Not leaking oil.


try replacing the oil preasure switch, if that doesnt solve your problem then have your oil preasure tested, if it really doesnt have oil preasure it will cause internal engine damage so start with the switch and then go from there, hope this is helpful.

E2200 oil light comes on when cold then goes off after warmed up. The oil level is good


try replacing oil preasure switch, if light still comes on then have oil preasure checked , (when cold) may need oil pump if presure is low, if you caught problem early you wont do any engine damage, again start with the switch .hope this helps.

I have a 1998 Jeep Cherokee with a 4.0L engine. The oil pressure gauge usually stays around 40 on the highway but when I come to a stop it drops down to 10. Is this normal or is my oil pump getting ready...


No this is normal. As an engine wears then oil preasure will be less this is not due to a weak oil pump but wear in crank shaft bearing's. When an engine is new and bearings are tight then oil preasure wont fall a lot from reved up to idle as the engine wear's oil escapes quicker from the crank shaft bearings. Reved up oil preasure increases idle it drops off. If the oil light stays out then their is enough preasure to lubricate the engine. In fact in an older engine high oil preasure is a worse complaint as this means the oil system is clogging. All is ok with your pump. If the oil preasure is moving up and down at constant rev.'s then the oil pump is faulty. Hope this put's your mind to rest.

Oil and handbrake lights flashing peugeot 106 s2


Hi, If you solve engine idle speed fault this will stop warning lights.
Oil preasure falls when engine not at norm rpm because oil pump is not turning fast enough.
Put car on diagnostics to check for any fault codes

Oil light flashing occasionally


It could be a faulty oil sending unit, but it would be advisable to have the oil preasure checked with a mechanical guage to determine if it is a sending unit or low oil preasure. Oil preasure low enough to allow the light to come on is low enough to possibly cause major engine damage.
