Is the white smoke steam or oil vapor? If it's steam, it just needs to warm up, if it's oil vapor it's probably pretty serious. Same with the knocking. It could be timing or it could be a rod bearing or any of a number of potential problems that fall somewhere between the two in severity; it all depends on what it sounds like.
Cause low pressure oil pump
need a new engine most likely. driving dry or on low oil for a few miles will cause that..it will be cheaper for you to just get a used engine with lower miles from a junk yard than taking it apart and rebuilding it..
When the fuel in an engine cylinder ignites prematurely or unevenly to cause power fluctuations and a "knocking" sound. usually occurs when an engine is very how or improperly timed.
Engine knocking can be caused by numerous things. Having the incorrect spark plugs, carbon deposits on the cylinder walls, and being low on engine oil may all cause a knocking sound.
can you elaborate? engine noise? stationary/moving? ticking, tapping or a definite knocking?
Bad bearing or rod
Yes, fouled spark plugs can cause engine shaking, and loss or power. I'm not sure about knocking but I'd guess that too.
Having a bad rod bearing could cause a truck to make a loud knocking noise and shake when driving at high speeds. The engine having a coolant leak or an engine timing problem could also cause the knocking noise.
engine coolant getting into an engine cylinder from a bad head gasket , cracked or warped head
A bad harmonic balancer can cause a knocking noise. The harmonic balancer doesn't actually produce the noise, but it can cause the noise in the engine.
no installig a starter wrong will not cause engine knocking. all that will do is maybe short fuses, heat up wires, ruin your starter, or melt wires. knocking isn't electrical it is mechanical like lifters, pistons, valves, things like that
A bad rod bearing
Running too lean.
There are 2 typical noises that can be called knocking with the engine cold, that descreases or goes away when warm. The first is a minor problem, but still should be corrected before it creates a big problem - one or more hydraulic lifters "stuck"; as the oil heats up this can often clear itself up. The second is a more major problem, and that is connecting rod knock, usually indicating the bushings are bad and will eventually lead to destruction of the engine if not fixed. There are other noises that change with temperature, but these are the most likely ones you have experienced.
It may be map sensor but engine knocking cause of another reason. You should check your spark plug , I.S.C valve , Injector and engine Compressor. thanks It may be map sensor but engine knocking cause of another reason.

after market oil filter have been known to cause engine noises in kia's
maybe the carberator i dont know im not a machanic or anything
I would recommend taking it to a mechanic and have them listen to it. Everyone's definition of "knocking" is slightly different. Try not to drive it for too long; engine knocks can usually cause pretty severe damage to an engine.
No. A bad head gasket would cause water to come out the tailpipe. You will see white smoke. Leaky rings would cause oil to come out the tailpipe. You will see blue smoke.
It could be the cause of the knock only if the gasket was bad and leaked out almost all the oil.
Low oil or low oil pressure, bad oil pump, clogged or gummed up lifters or even thin oil can cause low oil pressure. All the possibilities mentioned can cause the engine to be starved of lubrication. Which in turn creates friction that heats the metal engine part so that their tolerances change. Change in tolerances between two parts can cause knocking with increased heat from this friction.
You've more than likely overheated the engine and cause a head to crack, or you've blown a head gasket and it's going out the tailpipe. Is there steam coming out of the tailpipe?
