@@rock-uu7qr not BS, I am a diesel mechanic, I know my stuff. Most diesels have fixed tappets, meaning tappet rides on camshaft, this pushed pushrod, pushrod connects to rocker, and valve lash is exclusively adjusted at the rocker. The 6.5 uses hydraulic tappets, meaning the hydraulic (self adjusting) tappet rides on the camshaft, this connects to pushrod, pushrod connects to fixed (non adjustable) rocker. There is, therefore, a degree of dynamic play that changes based on load and other conditions. When backpressure is added due to an exaust brake. There is reverse pressure on the valve as the piston comes up, when the back pressure pushes on the closed valve, it can push against the oil in the lifter and open the valve, thus contacting the cylinder. Word of advice, anybody in the comments can be a diesel mechanic, I happen to specialize in 6.2 and 6.5s.
What size brake are you using? Have you ever seen a true 5" brake? I can't seem to find one anywhere that isn't just a 4" with an adapter.
Im using twin 4" exhaust brakes never seen a 5 before lol
Sounds good
I see you got your wiper fixed haha
That was fixed the mornin i woke up lol and reinforced too
I really hope your not using an exaust brake, it'll make valve hit cylinder soon enough, hydraulic lifters mate
Been using it for like 2 or 3 years
@@dieselnation555 Jesus, well, do what you will, can't be good.
@@bikingwithcamo5469 i got 2 spare motors and the one i got in her now is a 82 6.2l paired with the nv4500 only cost me 500 bucks so f it lol
@@bikingwithcamo5469 What kind of BS are you saying? Many diesels run an aftermarket exhaust brake especially people that tow with them
