My car loses oil about a quart every 1000 miles. i forgot to put oil in and now it is very loud under the valve cover but only at 1000 to 1500 r.p.m.s if the r.p.m.s goes higher than the noise is aleviated like the isnt a problem. sometimes the noise is real loud and other times just loud but only between 1000 to 1500 r.p.m.s i took off the valve cover for the front and had it started and a bunch of little jets were shooting oil out so i dont think i burned out my pump. i believe the hydraulic lash adjuster(s) is/are bad. how do i check? do i replace just the bad ones or all of them and how do i check to see if they are bad? please help. thanks everyone!!
Difficult to say.
Chances are all of the valves and lifters along with the cam bearings have been damaged due to lack of oil. To what degree of damage or excessive wear is difficult to say.
You might be able to remove the lifters and examine them but it might make more sense to replace all of them to be sure.
Expect more noise as time goes on from the cam.

Sounds like you have one of two problems. If the car has over 80,000 miles on the odometer, your idle air control motor (basically an electrical solenoid valve which allows additional air into the motor past the closed throttle valve) is sticking open.
The other possibility is a vacuum leak. I would try removing the IAC (idle air control motor) and cleaning it using aerosol carb or throttle body cleaner. This is available at any auto parts store. Re-install the valve and see if there is an improvement. If it improves but reverts to it's old behavior (usually within a day to a week) you will need to replace the valve.

I have the same exact problem.....1999 Galant! The water is in the center of the floor board and also under the seat to the back floor board!!
SOURCE: loud knocking or tapping sound when engine is cold
Take our oil pan off from under your car and there should be 4 to 5 covers over a rod bearing. wiggle each one of them and find out which one is loose. take that cover off of the one that is wiggling and get the rod bearing out. order a new one from auto zone and replace it. The knocking in your motor can end up where you will need a whole new motor. so get it done before its to late.

THe timing of the oil pump is irrelevent as no matter where it is timed as long as it is pumping oil. you must have a leak from a cam or crank seal or maybe the oil pressure sender. hope this helps. regards Ben.

It is a lifter ticking. They are called hydraulic lifters. They have a spring inside them, when the car is running it builds oil pressure. The oil pressure fills the lifter which gives the lifter a cushion so to speak. When a lifter is worn out it will not hold oil pressure as well as it use to. So I would say it is a lifter ticking. Nothing to be real concerned about. I had an old 6 cylinder that all of the lifters ticked in it and it ran forever. Probably still running somewhere! So it is not really a concern. If you want to you could run 10w40 oil in it, which is a little thicker. This may help.
