o-rings bad. okay to drive

[materi]

i have a 1996 f-250. i believe the o-rings are bad because it smokes a ton when you first fire it up, then does not smoke when warmed up. i was wondering if this is okay to drive like that for awhile or should it be adressed promptly. i am thinking like about 5-6000 highway km's will be put on before i get a chance to get them done.
thanks

Sounds more like a glow plug problem to me.

Sounds like glow plugs or glow plug relay.

my thought is glow plugs too, dose it take a while to start whin its cold? what color of smoke? and check ur oil, if the injector O rings are bad u'll have fuel in the oil

If your injector o-rings are bad you will have oil in your fuel. To see if they are bad remove your fuel filter and drain the housing. Wipe the inside of the housing with a rag if it changes from a blackish color to an aluminum color then they are bad.

But I still agree with previous check your glow plug system.

when i bought the truck the dealership said they replaced the glow plugs already. the smoke is blueish. any special precautions to checking glow plugs or just remove one by one. how do i know if they are bad?
thanks

You may want to run some injector cleaner, like Diesel Kleen through it. It may just be dirty nozzles.

is it okay to drive like that for a while or will it wreck something else?

I'd assume you'll be okay. As long as the smoke goes away after warm-up.
Here is a link on checking the glowplugs.
