2.4 L engine timing chain noise

[Tsschnare]

I have a similar noise mainly around 3 rpm but it was never there and it just came after I down shifted 2 days ago

I think there was a TSB for 2001-2002 2.4's, where there was a problem with the chain not getting enough oil....the orifice hole that lubed the chain could get plugged...also a potential problem with the tensioner....this would cause a slapping of the chain......

You would get a timing kit....new chain, new tensioner, new cam sprockets, new crank sprocket, new orifice(larger opening)....

I just started hearing this rattle, knock or tap in my engine. When its cold it runs like a dream. As soon as it starts getting up to temp or above 2000 rpms it does it and gets worse as it reaches temp. I would like to try and pin point issue before blowing money on this car. Can anyone help????

You have to isolate the noise first...top end, bottom end, or from the front cover....

Pontiac Sunfire Sport 2000, 2.4L
have the same problem with the clicking noise....but also the vehicle has no acceleration power. if I push the gas peel to the floor...it won't accelerate and will only move slowly...about 10-15 mp4 max...the timing Chain was repaired 2 times before but after just replacing the alternador, this occured. I changed the 2 electronic coil packs and the control module and the car ran like a champ for 4 days....now I am back with the exact same problem before. is it the timing chain?
