please watch this video....whats wrong with my truck??
 

So i replaced the tappet cover gasket....therefore removing the ip and resetting timing to 14.5-15* first it was at 16* but i set it back to 14.5-15* thinking that was a problem. I also added 4k gov springs and 60 lb valve springs. Since I have pretty much ruled out timing through checking it and retiming it I am really not sure whats wrong.....new hypothesis is a pushrod is off and not allowing a valve to open so its exploding inside....its pretty loud...anyway heres the vid please help
Thank you for your time

and heres the link if that doesnt work:

im going with a rod knocking cus that's what mine sounded like except it wasn't that loud other than that i dunno I'd wait for some more input from the big guys

I'm not thinking it would be a rod knocking ....its more of an explosion/detonation sound....it ran like a top before the repairs/mods....only got 117000 miles on it but thank you for the input

:argh: Sounds like a problem in the valve train. Check pushrods and valve settings.:tttt:

im thinking something wrong with a pushrod

i dont think its a valve not opening. if you had a stuck exhaust valve you wouldnt be able to release the burned gases, and unable to take in more on the intake stroke. i would say it sounds like pre detonation by how quick the pops are coming.

somthing went wrong with the installation of the valve springs.

i agree and they can be very loud to once they get bad when you revved it up that's exactly how mine sounded but it wasn't that bad i'd say you might wanna take it to a shop if you feel like driving it and let them have a look at it

Wouldn't hurt to pull the valve covers and take a look. :c:

Well thank you for all of your input. The problem proved to be quite nominal. I had gotten all of the valvetrain correctly installed.....HOWEVER...i rechecked valve lash and on the fifth cylinder exhaust I didnt get the locknut on the adjusting screw very tight so that explains how the problem worsened and was fine at start up....through driving it the adjuster backed out and the pushrod came off therefore the exhaust was not opening so I had an explosion that couldn't escape in my engine. the pushrod was off to the side and obvious through visual inspection. I removed it and it was not bent, rechecked valve lash and tightened those locknuts down tight. It runs awesome now!!!! thanks again,
Justin
