3,200 RPM spring cut

[mhuppertz]

sounds like you ware making a hi-speed run and even thow your REV spring was deefueling becouse yu ware runing past 3,200 rpm you keep going ontill one of the valve springs let go

you do know that they cummins need better valve springs for over 4,000rpm ?

even thow your pump was deefueling you still had enef fuel to get close to the 4,000 rpm limit of the stock vlave springs ---- and than your wheels hit a little bump in the road cozing them to bounce thus over REVing the motor

this is my guess --- and yes I have seen this happen in other cars and turcks ---- it all comes down to the driver pushing his motor past the limets

Looks like a piece of valve to me too. Flip the head and take a look!

It is a piece of a valve, and they did float.

We (Fatty and I) have had this argument many times where he says it has nothing to do with heat, and I say it was a combination of heat and valve float.
