First thing is to NOT attempt to run or drive it. Knocking is a sure sign that serious engine damage is starting to occur. Either your oil pump has failed or your engine is worn out. Take the car to a shop and have the engine checked out. A mechanical oil pressure gauge will give an accurate reading of how much oil pressure is actually there. A compression test will let you know the condition of the rest of the engine.
I would take it to an engine rebuilding shop for an assessment, just check to see if they have some experience on imports. They would be the most knowledgeable on what to do from here. You may be able to simply install a new oil pump and be good to go, or you may have to look at rebuilding or replacing the engine, but a few bucks right now at a professional shop could save a lot of time and money being wasted.
Hope this helps.

2004 Ford explorer engine knocking

take it to an accredited service shop that has experience on your make of engine and have a proper diagnosis done and quote
it is possible that there is a spinning main bearing and the test is a oil pressure test using a mechanical gauge
some times it spins , low oil pressure -knocking other times it stops and the oil pressure goes back up , knocking stops
should I be correct , normally it can be repaired in car by removing the sump and replacing that bearing shell, of the shaft is not damaged
i would steer away from a new engine or suggestions of a blown engine but it could be serious

A knocking that starts when engine is cranked then it goes away

The knock is likely a worn connecting rod bearing. Are you using the correct weight of oil, never use any heavier than 10W30W, heavy oil viscosity's cause slow circulation through the oil passages and starve the engine's bearings for oil.

Noise in engine happens when it sits for 30 minutes or longer and sounds like a knocking noise coming from timing chain area and goes away after 5 or so seconds. Is was told by a dealership that it could...

possibly the incorrect oil filter in use
quality filters have an anti-drain back valve where the cheaper ones do not
it doesn't have to be left overnight to do an oil pressure test as it is just a matter of removing the oil sender unit and screwing in a mechanical gauge

whistling noise is prob. intake leak or emmissions air flow problem, the oil gauge, is either , oilpump screen clogged, or gauge prob. or if a lot of miles it could be the engine is just getting weak, or oil pump itself. check oil level, and sensor for leaks .

I have a knocking noise at idle in my 97 Chevy Lumina...It goes away when I accelerate. What could this be?

after oil change' check oil pressure cold and then hot , then idle, if it goes up when reving it hot, thats good sort of,then if it goes way to low at idle and knocks, check idle speed. Fix it if so, still there , in the old days we would be cheap and put in a high flow oil pump, now I drive the "siht" out of a cheap car to see how long they last! It will supruse you> seen a 97 lumina with 400,000 km. slight knock and still going.

Oil pressure gauge reads normal when first starts. as it warms up, gauge goes to zero. If I rev engine, gauge goes back to normal.

Two things...when it reads zero, is there any engine noise (tapping or knocking)? After you rev the engine does the pressure read normal at idle and function normally, or does it go back down? Either way, you should not drive the vehicle 'till you have a mechanical gauge (yours is electro-mechanical) put on there and the actual pressure is tested. The condition may be a bad sending unit, a bad bearing or possible obstructed oil pump screen. The repair is obviously different for each one and the price is as well.

Low,fluctuating oil pressure on 1993 blazer 350cid

If your vehicle has over 160000 miles on it and the low oil pressure is accompanied by engine noise.Chances are you have bearing clearence problems and or oil pump issues.The oil pan should be lowered for inspection.If there is no noise from the engine,install a manual aftermarket oil pressure gauge to make sure the original oil pressure gauge isnt faulty.Good Luck!!!!
