#8 of 15 LOUD Rattle from center of vehicle
Mar 05, 2007 (7:26 pm)
I have a loud rattle in the center of my 2002 Chevy S10 ZR2. It is very loud and sounds like cards in the spokes of a bike. It is constant and only quiet when the vehicle is in neutral. What is it and how do i fix it....cost? Any help would be great.

I own a 1999 S10 and it rattles very loudly at idle and below 10mph. I found the catalytic converter to be the cause. More specifically, the internals of the converter were "rattling" around inside of it causing the noise.

Sometimes the catylitic converter's heat shield becomes loose when the spot welds fail. When this happens it creates a terrible racket.

Check the oil for gasoline smell, them V6's had a lot of fuel leakage problems under the plenum.

If noise is with a cold engine and goes away hot, maybe infamous piston slap.

I am not sure what piston slap is but yesterday when it started the oil psi went over 80psi for a few mins then went to 40 when i put it into gear it went back to over 80 it fluxuated back and forth a couple of time and then staied at 40 at the time the lifter of valve noise was louder that normal i didnt use the truck this morning I called a repair shop to drop it off tonight when I started it to night outside temp was 70 it still had valve noise but nothing like yesterday i thought yesterday it was going to blow
