Driving in L9 and DFM

[Garth Knight]

Yeah, in regards to the 6.2L, does driving in L9/disabling DFM increase or decrease the likelihood of lifter failure? Anyone know?

Looks like they'll never be a Range or Pulsar LT device for our rigs. Bummer.

Is there is any evidence to indicate that disabling DFM electronically will prevent lifter failure, since the collapsible lifters still remain?

I have my doubts driving in L9 would be the perfect solution as when in Park the DFM will probably kick in while idling...if that's the case, then the issue is still going to crop up. That's just my take on it.

I've had one side replaced at 9,100...currently at 11,500 and a little leery as to when the other side will decide to go.

I'm glad I'm not the only one lol

Instead of putting in D select L for low and use paddle shifter to 9 for 9th gear and it dont do to 10th gear and go into dfm
