Educate me: '02 7.3 PSD, Glow plugs, white smoke?
I have an '02 7.3 PSD. I noticed last year in the fall that unless you let the truck warm up real well it was very loud, gutless and if you got on it right away it would belch out a lot of white smoke, start running rough, then quit. You can turn it back over with the pedal on the floor and it would slowly come to life still belching white smoke and only making 2000RPM in park. Let it warm a little and it is fine. Oh, did I say it is loud? I know my neighbor hate me in the winter when I click-ity-clack down the neighborhood at 4 AM at about 30 mph.
What I have researched so far are the following with no definitive answers
1) plug in at night (Done, easier start but still has to really warm up)
2) HPOP oil change (Seems to be a very subjective topic with no real positive linkage)
3) Change and keep oil level right (I do this anyway but don't see a connection or a difference)
4) Glowplugs and/or relay (just not sure here).
As far as the glow plugs, do they stay on for a while after the truck is running? Will the relay initially work and then fail under a load?
Thoughts and comments please
