finally got my trans problem fixed and now another! seems after driving my truck for about 1/2hr it starts squealing :crazy:

i thought maybe it was coming from the trans/converter so i unbolted the converter from the flex plate and nothing.

also unbolted the stater with no luck, any idea guys :dunno:

here is a vid of the noise, when im driving its about 5x louder then in the vid

noise starts at 1:05

 

cracked flexplate perhaps?

 

problem fixed!

this is what the problem was http://www.silveradoss.com/forums/in...0&#entry709970

 

You need to check all your PCV hoses. There is a restriction somewhere.

 

interesting

 

Is this normal for the higher Hp engines, or does this go for my modded 5.3l as well?

 

I had a 6.0 with a Whipple come to my shop for the same problem. It was installed incorrectly. Both PCV hoses were eliminated. All the pressure in the engine had nowhere to go. After it was shut off it for forcing it's way out the oil fiter cap. I fixed it by adding PCV hoses to both valve covers.
I had another Ford with the same problem. I found a collapsed PCV hose. The Ford made the noise while running. When I removed the oil cap it stopped. Replaced the PCV hoses and problem solved.
