Took the truck around the block tonight, shifts nice. Needs a posi, tires go up in smoke with a tap of the throttle. Has a very loud whistling noise coming out from the engine compartment. Not sure how to fix that. Has an exhaust leak on the passenger side somewhere. I think its the silicone gasket between the manifold the the noisy whistling thing.
See my truck data in the "My Garage" section here... http://www.ls1truck.com/forums/my-ga...tml#post191709
my x over to manifold is leaking at the flange with that silicon gasket stuff also...soon as i get a gasket for it i will see if thats my problem with that side 02 sensor...
