What you're hearing is what I call the "death rattle". My 97 cav did this for about 2 years. The cause is due to your timing chain. Mine had this problem, until it pulled a piece of steel off of the tensioner. When that happened, it jumped time, warped all 4 exhaust valves, and cracked the head. I suggest a new timing set. Namely gears, chain, and a new tensioner.

my 96 does the same thing...and i too have been trying to figure out what its from...if you figure it out plz email me or post or something [email protected]

The timing chain guides are plastic and they wear, allowing the chain too much slack. The chain then flutters, giving you that rattle. Just replaced the chain, gears, guides, etc 3 months ago on mine. All is quiet now.

Don't have the bill handy so I really couldn't tell you. Parts:chain,tensioner, cam & crank gears,guides.

The parts I bought costed around 200 dollars.

theres a rattle in the 97 with 2.2L out here and i found that the tabs that lock the oil filler neck cap and stick down to the neck were broken and the cap was just sitting there rattling around making a metal rattle noise,

check that and make sure first hehee

a/c compressor might be noisy too, check that
