#554 of 4972 Engine Noise at cold start up for 2001 Malibu
May 24, 2001 (4:22 am)
I recently purchased 2001 Chevy Malibu LS. When starting up the car, anytime it has been parked for eight hours or more I noticed a ticking noise that goes away in a couple minutes. When I took the car in for an oil change I asked for this to checked. I was informed that the reason for the ticking noise was because the 3.1 liter engine uses a short skirt piston. This reason sounds like BULL to me, I suspected valves or lifters. Has anyone experienced this?

I just purchased a new Grand Prix about 10 days ago. It's the one with the 3.1 L engine so I would imagine it's the same engine as the Malibu. I haven't heard any ticking noises in my car. If you're already getting an oil change, I imagine you've had your car longer than mine. How long did you have your car before this started?

GM issued a service bulletin about this. It is more than likely piston slap. It is a know manufacturing defect in GMs 3.1 V6. Speaking from experience, I would be leary about getting the repair done unless you absolutely need it.
It took the dealer 5 days to do the job (Would have cost almost $2000 if I had to pay for it).
Problems since the repair...1- The car almost overheated one day. Checked the coolant, and it was bone dry. Oil also had a funny smell to it, I thought for sure the head was blown. Dealer had it half a day, said there was an "air pocket" in the coolant system which worked it's way out with driving, therefore when it looked full, the coolant was actually low as air was in it's place. They filled the coolant, changed the oil for free. It still smells the way it did, so I hope I was wrong. 2-Burning smell coming in vents. Beats me as to what is wrong.

How do you find out about service bulletins? I know some are mailed to car owner but is there a web page for looking these things up?

GM is so on the up and up with this, that it is a service bulletin sent to dealers. I believe you can read about it on the NTSB or NHTSA web sites. Owners of the vehicles are on their own to find out about this potentially serious engine problem. GM has not come out on their own to say anything, and the government has not made them. Nice, huh?

It's been a while since I've posted something on this board although I do check in regularly to see what's going on. I have a 2000 Malibu with a ticking V6. My dealer swears the problem is NOT piston slap, but actually the fuel injectors. I'm really concerned about the post from sparky51 who has a 2001 with the ticking problem. This has been going on for a while now, more than a year, right? Does this mean CM still has not corrected the problem during engine production?
Another question I have is what are the long-term affects if repairs are not made? I don't know whether my dealer is correct, or not, about the fuel injectors, but they are not about to replace the pistons in my car. After 16000 miles, the engine is reliable, powerful, and does not use any oil, etc. If this is piston slap in my car, I'm inclined to think, maybe incorrectly, that it's not all that serious.
The only thing that is occurring in my car now is rattles showing up from several places. One particularly annoying rattle is coming from under the dashboard. I'll try to fix it myself as the dealer claims they don't hear anything. I guess I can't really blame them too much for not wanting to tear the dashboard apart for just a rattle.

Hello everybody. I have a 1998 Chevy Malibu LS and has owned it since new. The V6 has roller lifters and rockers for fuel efficency and more power with less friction in the valvetrain that will rob power. Those noises are most likely the pushrods pushing up on the rockers and the rollers on the lifters and rocker arms making noise until properly lubed with engine oil and engine operating temperature reaches the first or second notch above the half mark on the temperature gauge. This is completely normal. I have over 70,000 reliable trouble free engine miles with no oil use in between 5000 mile oil changes. Do not worry or panic. The only major repairs I have had were Alternator and a brake job that was first done at 56,000 miles. Yes I get some brake rotor vibration with the so call new rotor design, but because I ignored it for awhile, it has actually smooth out. To get that perfect new car brake smoothness I'll get them resurface one day. This car has been driven every weekend for 3 years (no lie) for over 300 miles and she's still strong as brand new with 27 to 32 mpg of gas. Small gas tank makes this car look like a guzzler but it actual isn't.
Anybody with A/C problems meaning system cutting on and off at will should have dealer look at wires near the Air Intake hose on a sensor. Had to a chevy dealer that had the car every spring and could only temporarily fix it. Took it to my selling dealer and the fix was done right and hadn't been back since. These compressors are the Delph Thermal System V5 model and it's a continuous varible operating unit that cools interior on the demand of the system and outside ambient air conditions. Ex. Very hot outside, compressor runs at full capacity and both varible engine cooling fans run at full speed. Cool outside, Compressor runs at lower capacity and the engine fans run slower and quieter. It's a smart car but it can be annoying when you want cold air anytime, but it saves gas and part wear.

I had an intermitted dash rattle with 2000 Buick Regal. No rattle at all most of time, but a very bad on some pavements with some speed, for miles. Not a big problem - my wife did not pay attention at all. However, the specific pitch was annoying me very much.
The service adviser at dealership refused to fix it: too much work for the small nuisance.
I found a road near the dealership where the rattle happens reliable every time. Than I made an appointment for a test drive with service manager. He did not like the rattle too and ordered the problem to be fixed.
My car was at dealership for 3 days. The dealership mechanics had to dismantle the dash three times - the rattle disappear only after the third attempt.
A month later the same rattle appear again. This time the mechanics and manager found the dash panel to be warped. They ordered the whole new dash panel, replaced it, and the rattle disappear.
So it helps to be persistent.

My brother bought a Malibu a couple of days ago so I'll keep up with the service bulletins posted in NHTSA and NTSB. He doesn't have much use for computers. As long as I'm looking up stuff for my car, I may as well look up stuff for his as well.
The dealers are supposed to notify us of recalls aren't they or do we have to find out about them on our own as well?

TSB is not a recall,safety problems are a recall and you will be notified.An engine knocking is NOT a safety related problem.
