Thread: impala 3.8

have a 2002 impala 3.8 has ticking sound and i think its the lifter so i changed oil and use motor flush to see if that help but no difference so need help and advice on how to replace the lifters thanks

I'd even throw some trans fluid in the oil to see if that will help quiet the motor down, it may take several hundred miles to start working.

And I wouldn't rule out an exhaust leak but I'd have to hear it to see if it's really a lifter noise or something else.

how much trans fluid would i add

after i change oil i basically let it run to temp to see if it stop but it didnt so i turn it off nd then i had to leave for work

yea im have to do the upper and lower gaskets so i just wanted to be sure while i pull apart

lifter tick is no big deal

ok i havent drove it cause it acted like it was losing power when accelerating

How much trans fluid would i add also how many lifters it is to replace

sound like lifter ticking

oh no dont say that i hope its not a rod oh no

make another vid, this time hold the gas to say 2000-2500 rpm's, then just drop the throttle, let it drop back to idle on its own.

ok so rev it to rpm and then floor the gas u mean

And that just sounds like a poor quality phone recording, it can't handle the noises the car makes and it's all choppy and scratchy.

Try recording the noise with something else.

dont have nothing elese to record with at the moment when i first started it up

ok i let it drop and it actually dont sound as loud as it did earlier

you can stand at the bumper to make the vid, dont bring the cam in close to the engine.
