Morning Smoke
I have a 1997 f250 hvydty 7.3l with a Banks 120hp Power Pack system on it. My current problem is morning smoke (alot) when cold. If I plug the block warmer in overnight, I do not get the smoke. Blue in color. Any suggestions on what I,m looking at?

The only thing I can think of is maybe oil. Might it be getting past the engine rings when the are cold. I guess when my old car blew blue smoke it was oil, but I knew that was oil. Not sure what this could be.

It could also be a seal failure in your turbo or valve seals, or maybe something minor like a stuck PCV valve.
How many miles do you have on your 7.3?
Blue smoke means burning oil. You need to find out where it's coming from.

Well, at least you can say it probably isn't the injectors, glow plugs, turbo and pedestal, filter housing or lift pump.
Check your PCV valve, see if maybe oil is getting through it to your intake.

WELCOME to FTE! I am going to move this thread to the 7.3 forum, you'll get lots more answers there.
Good luck with it.
I wonder, why not just bring it back to whoever did all that unnecessary work ?

Oh, and if it's plugged in it doesn't smoke on startup? Doesn't that preclude any sort of seal issues?

Vavle guide seals tend to leak on intial start up. When you plug it in, it keeps the engine warm enough(vavles&guides) so that on start up the exhaust guides don't let oil get sucked into the exhaust.

The GPR is under the decorative cover on the engine. Remove it and look for a starter solenoid looking thing. Next cold start, take a screw driver and cross out the 2 large terminals on the GPR for about 30-60 seconds. Jump in the truck and start it. Come back here and Let us know what happened.

It is an issue of trust in ability. The parts were replaced per their recommendations and statements that they would fix the issue. He seems hung up on his diagnosis computer. It says everything is working fine. I have lost faith with him. If any of his work fails, he has a warranty
