Chirping Noise
I have a 97 4.2 with a 5 speed manual tranny. When I start the truck up, initially there is no noise, but after a few seconds I get a chirping noise which sounds like it is coming from the crankshaft area. This morning I took the belt off and started it for a few seconds and the chirping noise is still there, so that rules out all of the other pulleys on the system. I have replaced the harmonic balacer - a $300 + item from ford, and the noise is still there. After driving around for about an hour this noise goes away, but let it sit for a couple hours and try to start it up again and the noise returns, it sounds like chirping. It is definitely coming from the crankcase area, I however am not positive it is in the crankshaft, just sounds like that's where it's coming from. This noise happens whether it is moving, or whether it is sitting in neutral in the driveway running. Does anyone have any idea what this noise could be? I would appreciate any information. Thank you,

timing chain, crankcase oil seal on the timing cover, etc. Any of these might be the problem, but I'd bet if you pull off the timing cover, you'll figure it out.
Are you sure you don't have a cat stuck under there somewhere?

Thanks so much for your help guys. I was also told it could be the cmp synchronizer? A man down the street from me had the same chirping noises a few months ago on his 5.4l ford. He said he took it in and the mechanic replaced the cmp sensor. Does anyone know how the cmp sensor would cause a chirping noise in the engine? I did check out the crankcase oil seal and it does have a slight film of oil on the outside of the crankcase. Would this cause it to chirp like a bird?(lol on the cat sounds) Any info would help as it is getting to where I'd rather walk to the grocery store and hearing birds chirping is starting to disgust me, and that is just sad. Please help. Thank you.
