Question: terrable white smoke at start up on 6.5 turbo

[towguy55]

WOW alll good responses. going to tear into it hopefully today and see what i can find .
I already ordered a set of quick heat plugs caus i do have the 60g's in it now so we'll start there and i already did the bubble test on the fuel line and tested good so if the GP's don't do it i'll try the extended glowplug chip...if it comes to that..is there one you recomend ?..and thanks again to all of you....great site !!

One thing that you can do is add our Lift Pump control harness to take over control of the lift pump. It will start the lift pump at key up to "prime" the system and also take care of the OPS blues where the OE oil psi switch fails repeatedly.

I think you will find that the plugs help a bunch. Be sure to lube the threads and the taps to prevent corrosion. I prefer dielectric grease on both.

AC Delco 60G's are slow to heat but are supposed to be self regulating so an extended glow should not adversely affect them.

I use 60G's w/ 12s glow time and after cycle, it starte in -30* unplugged and stops smoking pretty quick (under 30 sec of idle).

I am not saying duraterms arent quicker heating but 60gs are ok.

I think injectors and timing need to be checked.

I think he'll be surprised at how well it starts with a good set of Quick Heats installed.

Did WAP ever fixed the Quick Heats early failure?

The engineer was here a few years ago when they were having trouble failing in short period of time but nobody ever guarantee that it is fixed for 6.5.

Then, we still have issue posting as late as summer this past year.

It would help at this point which glowplugs were used. That would let us know if they can handle a longer glow time or if they are a slower plug and need a longer time to operate properly

Let me know how yours turns out.

Mine has Bosch Duraterms and a chip with extended glow times, but I'm still getting 5-10 seconds of white smoke on start up. I'm about to check through the fuel system. I've been suspecting a leaky injector for a while, but I suppose ANYTHING that would allow air into the system would produce a similar effect. I'll be replacing all the soft line up front and installing a gauge for testing.

Good luck!

You know what I was gonna mention injectors but didn't think it was nesasary because he is under 100,000 miles.

I swapped my injectors for new Bosch this past late summer and couldn't believe how much it improved my cold starts and start ups in general.

3500HD's probably go through injectors faster than most trucks. They turn higher revs and typically get idled alot which just adds time and more injection events to factor in. Then add in the fact that they are bought to be loaded and most get loaded frequently which wears on injectors.

IMO 100K is good for a truck that does occasional light towing and a decent amount of highway but towing rigs could probably use injectors every 50-75K . Thats my opinion so take it for what its worth.
