Check the oil pressure with a pressure guage. Sounds like it is very low.

SOURCE: 99 sl rattle in front when engine warms, not a rod knocking.

The solution is simple and easy, if not cheap. You have a defective upper motor mount. If you open the hood and look for the motor mount on the left hand side near the accessory belt, you will notice that the rubber has shrunk. THAT is the problem.
This will only make noise at idle at a stoplight and doesn't do it all the time.
I have a 1999 Saturn SL and have fixed this problem once by replacing the motor mount. The first time, it was just out of warranty and only had about 60,000 miles on it. It has manifested itself again (started a while ago - now has 114,000 miles on it) I am the only owner of the car and it is now 10 years old. I won't change it again unless they redesign the motor mount.
You can replace the motor mount yourself if you are somewhat handy - it will cost around $100 for the part if I recall correctly. Make sure you prop the motor up; it should take about 30-60 minutes.

SOURCE: Loosing oil in 06 impala SS

First, do you see oil leaking on your driveway? Have you looked under the car and checked to see if any oil is dripping?A rear main seal will drip down the front cover plate of the transmission sometimes from the inside, appearing like a front seal leak on your transmission but the oil will not be red fluid you would expect if that were the case. I would not worry about rear main unless you see a leak there. Look your entire engine over and check for leaks everywhere. Several small leaks can add up to an overall large oil loss. Correct the larger ones first.
Generally all seals will last far longer if you change your oil frequently using a good quality lubricant. If you are loosing some oil, use one of the oils made for high mile engines. I suggest you use a mild additive like marvel oil 1pint with every oil change...it removes sludge, carbon and varnish buildup without the drawback of knocking it loose all at once, where it could plug up your oil pump screen. (it also smells good) Change oil every 3000 miles for the first three or four intervals, then consider using a good synthetic oil. Synthetics far outperform any other lubricant in every area! Avoid overheating your engine...overheating does more damage to seals than any single other item...When seals get very hot they harden up, crack and fail.
Good luck with your car!!!

SOURCE: i have a 1995 impala

First thing I'd check is the optispark sub harness. Check both connections, the one by the optispark and the one on the passenger side of the intake manifold. Disconnect both sides and check for corrosion. This is a known weak spot on these motors.

If that checks out your going to want to start with the basics. Do you have spark and fuel? Pull the spark plug wire for a cylinder and using a spark tester test for spark while cranking. You want to have a nice blue spark. If you have good spark check for fuel pressure by hooking up a fuel pressure gauge to the shrader valve on the fuel rail. It should be in the high 40s - low 50s. If you have fuel also, check to make sure the injectors are getting a pulse using a noid light.

SOURCE: oil consumption, rattle, engine noise

Check under the hood and inspect the valve cover gasket. If it's bad it would explain why you don't see any leaks on the ground because it's probably burning off on the manifold. This ticking you're hearing is a lack of lubrication to the rocker arms. Apart from the valve cover gasket, you should get under the car and inspect the oil pan and oil filter for seepage. Best of luck on your problem.

SOURCE: traction light on , reduce engine power lights on

I know this is not a solution but I too started having this same problem today. Start car, runs normal then all the sudden it feels funny, traction control light blinks on and dash displays service traction control-reduced engine power. This causes my car to sputter like it is going to stall I have to pull over and turn my car off and back on to drive off (only for it to do it within the next 10 minutes). I thought turning TC off would work for now just to drive it, no not successful stil does it : ( I TOOK IT TO AUTO ZONE AND HAD IT SCANNED HAD A CODE FOR GROSS EVAC LEAK AND SOMETHING ABOUT THE THROTTLE PLATE/BODY NOT SURE IF THAT IS RELATED BUT THAT ALL THE INFO I HAVE ON THAT.

2000 Daewoo nubira's oil light comes on, not when cold, but after it warms up, and only while idyling, goes off after you gas. Car rattles a bit at idyl. Could it be a loose sensor? Jill


sensors do not cause a rattle
from your description there is something more serious that a sensor
it could be hydraulic lifters that are worn out as the car is 16 years old which would allow for excessive loss of oil pressure at idle

I have a rattling sound which is loud when my 04 corsa 1.2 engine is warm.I had the timing belt changed by vauxhall 6,000 miles ago.Took it in to vauxhall last week as the noise bothers me they did oil and...


Check the engine top heat shield and the undercarriage heat shields. They may be loose and rattling. Give 'em a bump with your hand and see if they rattle. If they do, tighten them.

The techs at Vauxall may have failed to tighten the upper heat shield when they replaced the timing belt.

When I push on the gas there is a rattling sound, when I let go of the gas the sound is gone. What does this mean????


it can be a number of things
is the car running ok minus the rattle
is the check engine light on
if your answers are yes then no
its probably just something loose like a heat shield
next time you drive try to locate where the sound is coming from
like driver side front or driver side back
then shake and wiggle everything in that area.
I think you ll find out its something very simple

Funny noise near engine when i step on the gas like a rattle then it goes away as truck gets warmed up.


This could be a loose heat shield on the exhaust system. You need to have someone look under the vehicle when the noise is occurring to determine the exact location.

Loud rattle coming from the bottom of engine. mostly heard after letting off the gas, starting and shutting off the vehicle.


Very hard to know without actually hearing the vehicle but,,,With what you describe,the cat/converter 'may' be making the sound.With the car off and engine cool,get under and give the cat/con a really give shove or hit.The insides of them do corrode and the internals make a very loud rattle.If this isn't the problem it will let you see if there is a loose exhaust mount that may also make a rattle.(The cat/con sound is like there is a very loose metal plate hitting something)Its actually the internals of the cat. that have broken loose and rattling inside it.Hope this helps
