Heres a video.. its not loud, does it at idle and when accelerate. Sounds like its one side only or maybe by the water pump and the pulleys beneat it. When i replaced my valve covers i checked the rockers and everything seem fine.. pls advice

Just did the same thing on another thread - pull the belts off, and see if it's still there!

Thanks rick! what belts should i remove? ac belt and alternator belt??.. i just ordered a mechanical stethoscope see if that helps

Rickman48

All the belts -run it just for a couple minutes.
If the noise goes away, spin your accessories by hand - the bad should be obvious!
In the other thread, it was the water pump.

72CUTTY

Thanks, will do that today when i get home!

screwdriver and put your ear to it. works about the same to get a general idea on where the noise is coming from... also some people use a piece of garden hose to see where the noise is generally coming from.

Ill try that piece of hose today. I ordered the stethoscope on ebay so ill get it by Friday..

So i try listening it thru a hose. It seems like the noise is coming from the bottom if the car. Either exhaust leak, fly wheel , distributor or tc? I was told once long ago like 2 years ago that my fly wheel was making noise, is it possible?

sicky olds

doesnt sound like it but dont rule out spun bearing.... for exhaust leak you can CAREFULLY put your hands over the pipes and feel an exhaust leak. for the flywheel cant you hand crank the motor and look at it to see if the teeth look good? or again while running it you can look at it to see how it is spinning.

im hoping is not a spun bearing! ill get under the car when i get home and check it out! thanks sicky!

72CUTTY

Okay.. the noise seems to be coming from the intake close to the distributor.

so i took my car to my mechanic last night. He seems to thinks its either the rocker arms need to be adjusted or the lifters. He will check it out on sunday!

Rickman48

Guess what!!
No adjustment on your rockers - or lifters!!


Replace the pair, if one is bad, and the stand which is for 2 rocker arms!!
If it was me, I'd do them all, as they're the same age and a wear component!!
16 rockers and 8 stands!! [and 2 VCG's]

im hoping it was the cheap oil i put in my car! but regardless my mechanic will check it out on sunday

72CUTTY

Well , i flushed my engine, changed my oil and filter , added the riselone and the noise decreased a little but definetly still there. Ive seen videos and heard lots of noises on youtube, my noise is not that loud. Hopelly its the rocker arms that are loose and just need to be tighten. We'll see on sunday!
