Well got a doozie for you guys I have been in and out of the garage all night trying to figure out what's going on with my truck...long story short I just ended up doing tfs heads new lifters pushrods etc truck went to the tuner and made some stout numbers and I achieved my goal of running 13s...15 passes at the track numerous hits on the street the thing ran fine until today. Now I have a nice squeal under medium throttle(motor won't do it unless its under load). Also the truck feels like it's down on power granted it could be the humidity but it just doesn't feel right. I know I have a header gasket leak which I was going to fix but I'm starting to wonder if it ate a lifter. If anyone has an idea or what's going on please let me know!

 

Squeal....is it the belt?

 

post a vid!!

 

Atomic no sir does it with the belt off which is what makes me think mabey it ate a lifter? And I'll try to get a video but I really don't even want to start it

 

And sorry for the lack of info but it sounds like a metal on metal/bearing kind of squeal no pulleys have play either or are making noise with the belt off

 

Dump the oil and look for shavings.
