Valves hitting piston, check the mech timing. Check compression, how is it driving? Could be a lifter or a rocker.

its drving pretty good i guess for ### it is its just that when i floor it the rpms hit 3000 and studder then after a while itll go back to normal.....it picks up speed well though aslong as i dont go over 3000 rpms....its just that the noise is so loud and annoying...

Wow that does not sound good. Check comp. first.

Look for anything loose around the engine that could be causing it. You'd hate to find out it was something simple after you pulled your motor.

Check compression, then go ahead and remove the valve cover. See if you see anything weird with rockers, springs, or as much of the valve as you can see. If you still see nothing, drain the oil and look for anything that's not oil (i.e. shavings, RTV, etc.). After that, you can try taking the oil pan off and looking at the rods and pistons.

That should give you a pretty good diagnostic idea of what the problem is. If you have any trouble seeing problems or you aren't sure what a messed up part looks like, just post some pictures of above circumstances.

Good luck!

a kid i know this happiend to sounded just like it. He ended up with a bad headgasket and bent valves

 

[turbox]

bad head gasket and bent valves???....what happened or ### caused this?.....i need help i dont want to fix it so it could happen again because i didnt fix all of it

 

[98eclipsekidd08]

this happiend to the kid because he was running 19psi on an all stock motor that wasnt the turbo one to begin with . you can also bend valves if your downshifting at to high of rpm's that can #### it up bigtime.

+1 on bent valves, just like eclipsekid said, high rpms down to low rpms in such a quick matter....
