how long u letting it warm up?
Doesn't sound like he does. :shrug:
To the OP, if you infact do not let it warm up before heading out with it in the morning when it's cold out try letting it run 10-15 minutes before you head out with it I suspect your problem will be gone.

It's a diesel, and when it's cold that's what happens. Let the truck warm up before taking off. The ebpv will still cycle until the engine gets to proper operating temps.

A high idle mod/tune will do wonders with cold weather warmups. If you don't have it done I suggest doing it.

With that said, I usually let the truck warm up 15-20 minutes before I take off. I refuse to drive the truck cold.

Are we in the 7.3 section? No ebpv on 6ls. Do you get greyish fuel smoke out the exhaust at the same time? you probably have a touch of stiction going on.try plugging it in should help.maybe switch to 5w40 rotella syn if your still running 15w40

Im in baton rouge n it still takes at least ten min to warm. Driving when the engine isnt at operating temp leads to blow by. Imagine how your engine feels having diesel in its oil. Unreliable oil cooler... diesel in oil... oil protects your engine... Picking up what Im laying down? High idle mod. You likey
