need help with a 96 2.2l

there's a knocking..well sort of a rattle coming from the engine near the pullies...its not the valves cause it does not go away when i accelerate....
and if the valves made that much noise the whole engine would have quit by now....it been doing this for about a year...
i tho8ught these engines made these noises....till i heard another 96 cavalier with the same engine...it was a lot quieter..
if any one might know what this is please tell me ...
thank you

help??
anybody????

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 vcbadass@yahoo.com

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.

about how much does this cost??? if you could give me list of what i need it would be great

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
