Thread: 98 Grand Prix GTP Engine Noise with video.

https://www.youtube.com/watch?v=MweQuJ5Z-kc

Ive been told its the pistons by one guy that replaced my head gasket and another guy told me that to him it sounds like its something with the valves. Suggestions?

I just had the supercharger coupling replaced yday so its not that because it was a whole lot louder than this before.

Why was a head gasket replaced? These motors RARELY eat HG's. The LIM gaskets go long before a HG gives up.

Do as suggested above and see if the noise goes away. If it does, then you know it's in a pulley somewhere. Could be the waterpump or A/C compressor from the sounds of it.

Just one day I was driving up the mountain to get to my for one of my finals and the car just started struggling really bad and losing power and I looked down at my dash and noticed that my car was over heating and it got all the way to the red and the light came on before i got to a place where I could pull over (which was probably less than 30 seconds) I had someone pick me up and then when they got my car to the shop they told me my head gasket was blown, so I just had it replaced.

The car runs fine now, Its just making that noise and Im not sure what its from.

We haven't gotten around to it yet. I haven't been driving the car the past few days. Wil update when we do, hopefully over the weekend.
