2005 malibu classic 2.3

Got this car from my mom always been maintained.hass 80,000 miles on it.wondering when is best time to replace timing chain to be safe.dont want to mess up engine.little motor has some power.jump to 6,000 rpms in a sec.was hesitant to buy because didnt have the 3.5.has a slight ticK sounds like in lower part by timing chain.go's away as soon as hitting gas.very slight tick.

Was curios that maybe chain strected or pully bad.heard in the 2004 and below there was a problem with tensioner.hope its nothing bad.my mom said it always had that tick from 30,000 miles.going to try different oil maybe a little thicker.any suggestions?

And also is waterpump right there with chain? I know if so probly do both.

I really dont want to chance chain to 125,000 with these ecotech motors.any suggestions be great.girlfriends car so be taking to chevy to get done.probly be 1,000.

2.2 i thought it said 2.3

This question might be better suited for the GRM board, so I'll move it there for you.

And for some reason I can't move it. Hmmm.

I just posted here because the car is a classic not really a classic but had to post.

LOL!!

In high school, I drove my parents' 1978 Malibu Classic. It was awesome.

This one drives pretty good surprised me.for that small motor.she probly wont drive it like i did,but had to test it out.

It's my understanding that the GM 60 degree pushrod V8s typically have the chain last the life of the engine. There is a sort of anti-rattle "damper" / chain guide (it's not a true tensioner) inside the chain that I could see being worn out. Probably won't do anything more than make noise if it fails, though.

The water pump is out in front of the chain, run off the serpentine belt.

Ok ill probly get it replaced before 125,000.
