Mine is not DoD so im really hoping its just a lifter or rocker something that wont cost 4 grand to rebuild lol. What should i get if it is that? Comp lifters and rockers with some push rods?

no just upgrade your current rockers with the comp cams trunion kit, its a fraction of the cost of new rockers and it takes max 45 minutes to install the push rods wait and see, if theres no damage to the ends then dont waste that money
i'd hope its not a lifter haha the head has to come off for that!

I would much rather pull the heads and do it that way then have to pull the whole motor for a rod/rod bearing. Lifter will be much cheaper then if there is something wrong in the bottom end.

Mine has 6k on it and it was the second time i got into boost it let go. Im hoping AUTO is right about the rockers being junk and breaking a bearing that would be a nice easy cheap fix. I'll let you know what i find.

Well i have bad news i got in touch with a local Ls Guru and he met me down at my truck we pulled the valve covers off and valve train is fine. He seems to think i have some very bad luck and a piston skirt cracked or rod bolt. So yea i'm screwed for a little while till i can enough money together for a rebuild.

Well I'm sorry to hear that man!
Listening to your video it really doesn't resemble a rod knock or piston noise but maybe the camera isn't picking up on it fully
When you do tear into the engine I'd start at the top cause if you pull the heads and it is a failed lifter you can stop there and just repair that!

Damn, that's some shitty luck man. Hope it's not that bad when you tear into it.
