    no ive been keeping an eye on the oil pressure and allthough the car is leaking oil i keep it full. It even does it while its cold, im going to change the oil and air filter and do a basic tune up to see if that will fix the problem. thank you for the post if u have any other info please share

If you can be more specific about the engine knock it might be helpful. I am assuming this knock happens after the engine warms up and can be heard while the engine is under a load. If it is a strong knock sound then it would be a crank shaft bearing. You may want to check the oil. Check for level and condition. If there are water droplets on the dip stick or anti-freeze in the oil, or oil in the anti-freeze, you could have a bad head-gasket. Redused oil pressure, pressure testing the cooling system, doing a cylinder compression test, could help in figuring it out. Also it is possible that it could be piston slap or the fly wheel is hitting inside the bell housing.

How do you turn traction control on and off on a 2000 chevy cavilier


try taking to a safe place with plenty of space to ride and stop. when it is wet or on gravel. accelerate and then try to stop moderately hard. if it turns on, it should be working fine. but, my guess is a hub bearing. do you hear and noises coming from either side of car during certain speeds or whenever you are making slight turns?

the knock sensor changes the timing of the motor when it senses knock ,it sounds like the wire may have come off ,it sounds as if when you press the gas the timing should advance and it sounds as if its not advancing thats why you are hearing a clattering noise on accelerating.if you keep driving it like that you can do engine damage

The knocking and grinding is not a good sign for the engine itself.

If the starter tries to start a seized engine, it will click and not turnover.

The engine may have to be overhauled or replaced with another.

might be the valves have been damaged running without oil
- or the crankshaft / camshaft / main bearings
most probably you have to let the engine be rebuilt by a mechanic
(expect cost of more than US$ 2.000)
or get another (used) engine at a scrapyard 2003-chevy-wutfveiel3ypko01ydor435x-5-0.jpg 2003-chevy-wutfveiel3ypko01ydor435x-5-2.jpg

Engine knocking noise in 2000 saab 9-3 SE?


It's a common problem with these cars i am actually fixing mine as of now. That car is all about oil pressure and when it is low you'll start to get a tap and or what sounds like a knock due to the lifters not having enough pressure. Try taking your oil pan off and check your oil pick up line going from the oil pan to the turbo. A lot of times it gets a lot of sludge build up and makes the pressure little to none. If that looks clear check the slump inside the oil pan and see if that has sludge build up. Well hope this helped
