Could be various things wrong, could be bottom end big end bearing. you need to establish where the knock is ( top end or bottom end ). if it is big end thats knocking then its an engine change ( saves messing about ) or top end ( camshaft ) then its a mornings job. hope this helps

SOURCE: loud knocking

Sounds like you may need a motor, or something in/on transmission. What is your oil pressure like?

SOURCE: what could cause a loud knocking in my car engine

It could be a rod that hase came loose from the crankshaft or the piston. It could also be caused by overheated cylinders firing on exhaust strokes or firing early on compression strokes.

I would have to be there to hear it. You may want to have it towed to a shop to get their opinion.
A knocking noise is usually a rod bearing or other internal engine part, and very serious damage can result.

Not getting oil to the pistons. Making knocking noise. Wont stay on.


Hello
Has the engine been run low on oil? Does the knocking get louder as the engine warms up? Have you had a automotive technician listen to this noise? Pistons don't really knock, the bearings in the engine called the crankshaft and piston connecting rod bearings do make a loud knocking noise, if that is the case the engine must be removed from the car and rebuilt.

My wife drove the mini van when it was low or almost out of oil. now the engine makes a loud knocking sound.......is the engine blown or is there a possible fix, to save the engine?


Knocking means you're still low on oil. Try have an oil and filter change. If your engine is blown, you won't hear or feel it cause it's seized. A dying engine from oil starvation would make screeching metal to metal noise. Yours sounds more like a stuck cam follower from oil starvation.

My 01 has a bad knocking noise what does this mean?


it means that you need to research either a different car, or a different engine for this car. A loud knocking noise indicates a connecting rod is loose, and your engine has little to no time left before the rod or endcap breaks, completely messing up your engine, and making it very difficult to change. If you must drive it, drive it slow, and be super gentle with the gas...like you're driving on ice. If it's more of a ticking noise, that could be a lifter, but a loud hollow sounding knock is a rod. You may also have a check engine light showing up on the dash from the knock sensor.
