I recently changed my Timing chain cover gasket. (leaking antifreeze) I put everything back together and now I get a squeaking noise. I checked all the pulleys and they're fine. I left the belt off and started the truck and I still have the noise. So then I thought I was my Harmonic Balancer. I changed that and have the same noise. I removed the balancer and started the for 4 seconds. I still have the noise. I now have no clue in what to do. I used pullers to remove the balancer and installers to install them. No hammers or such.

Can anyone chime in on the problem?

Thanks in advance.

 

Check the Water pump or Alternator. My truck squeaked so I changed the belt, when i went to change the belt I noticed antifreeze leaking due to the bearing in the water pump being bad. Also could be bearings in alternator, mine makes a very loud squeal at cold start due to alternator bearing. Once it gets going go (like 5 seconds, it stops.) just another idea

 

He said he took the belt off and it still squeeked. A member on here told me I could use a long hose as a stethascope and put it up against my ear and try to figure out were my knocking was coming from. Try that to figure out were the squeeking is coming form, then go from there.

 

The problem was the timing cover wasn't centered. Somehow the the keyway was rubbing the oil seal, I believe. I redid the whole thing making sure the crank was centered and it's quite as it should be. I now I got to drop this mobile 1 in it to complete the job.

Thanks for you guys input.
