View Full Version : Attention all 3.4 owners
07-20-2003, 03:16 PM
To all 3.4 owners . I have a 2000 Grand Am GT, engine code M.
This car is at 60k miles , and has been babied. The last 10k miles this car was making way to much noise under the hood . The dealer said that its a combination of a bad piston and loss rocker arms. Thankfully I bought the (ex) warrenty. I have a $100 deductable.
The funny thing is I go back to work and talked to a soldier in my BN. This soldier also has a Grand Am GT , it's the exacted same as mine except he has a two door . I explained what was up with mine ,so he asked me to listen to his . His is doing the same thing.
ANYONE WITH THIS PROBLEM PLEASE LET ME KNOW,IF THIS PROBLEM IS AS COMMON AS I THINK. MAYBE WE CAN GET OUR DEDUCTABLES BACK WITH A CLASS ACTION ON GM FOR POOR WORKMANSHIP.
My name is Ken Carroll

Is the noise that you heard the common tap that most people hear at start up time...the tap that goes away after the car warms up for a few seconds? Or is it a different noise that is present even after the car warms up? I believe that the majority of 3400 v6 owners have come to the understanding that this is a characteristic of our engine as annoying as it may be. But if the noise persist past a 2 min period after start up than there may be something else wrong. My engine does this for about 30 seconds after start up and then goes away. The colder it is the longer it will take to go away. I've never noticed it to take longer than 1 minute to go away. I have a GMPP warranty that will still cover me for a while so I'm curious of your findings. Good Luck.

That is how it started . But it proceded to get louder and now it will not stop . The dealer said that its a combination of lose rockers- a TSB , and a bad piston which is also on a TSB. The dealer is installing a new engine. I don't think they would replace the engine if it was normal. This engine sounds as though its going to throw a rood through the hood. And another thing a soldier in my BN is going through the same thing. Get with the dealers and ask to see the TSB's on this engine . The Grand Am GT's 99-2002 with engine code M have about 50 TSB's.

I have also been hearing the noise alot more often, since my sister said she heard it when she walked up to my car. I usually would'nt hear it myself since i usually have music playing loud. I stumbled upon this thread and it got me thinking about it. Is there a correction in place to fix this? I want to get it fixed myself if this is the problem. I like the guy a few posts earlier stated thought it was just a common sound from my engine bay.

The biggest problem I have is with a cylinder a TSB states that a coating is on the piston. When this coating is damaged the engine has to be rebuilt, this is what I've been told by the TEC at JIM CLARK a dealer in Junction City, Kansas.I'm sorry if I make people worry,but cars cost too much. Most of us need to know about this so we can fix this under warrenty hopefully.
Please keep me posted on these problems
If the problem is bigger than I think maybe we can get GM to eat the cost of our deductables at least. GM is facing a class action over DEX-COOL now.

Maybe I was out of line stating the name of the dealer thats working on my car. Its just that I go to church with Mr Clark, and I trust that he and his TEC's will do me right. They have in the past.

I got my 2000 GrandAm SE at 37,000
Since then this is what I've had done.
3 of the 4 wheel bearings
Upper strutt mounts
Rack and pin
ALL COMMEN IN GRAND AM's
Don't always go by what dealers say...Some don't care until it brakes down or others tell you stuff that isn't even wrong.
I live in Canada by the way.....

I'm happy to say that the dealer has me a new engine for me. But it seems to be taking way too long to install. They should me tha inside of one of the cylinders. The #3 was egg shaped.

I have my car back,with the new engine.There is a big difference.
I must have had this problem a long time. Now they have to fix the collent leak.
