White smoke off throttle?

[kc0stp]

Finnaly got the truck mostly back together (new intake and tranny cooler...Im lazy) and took it up to the foothills for a test drive (and just to see if the intake lowered EGTs any), going uphill everything was perfect (lowered EGTs 1-200 even though I have a boost leak I didnt last time up the hill thanks to my boost gauge hose blowing off) however coming back down when I was just coasting/engine braking Id get large plums of white smoke out the tailpipe so ended up just left foot braking/staying on throttle coming down so I didnt smoke everyone else out. I will admit I havnt gotten the CDR tube hooked back up yet and the downpipe is starting to fall off again (silly slip fit pipe...) but neither of those should cause smoke out the tailpipe... After stopping at the parts store for a new CDR tube checked the injector lines (engine off) and they were all about the same temp.

You may have posted this before, but......... how old are the injectors? A few leakers will do that.

PO says he replaced them twice in the 125k he had the truck but based on how well it was taken care of otherwise Im hesitant to trust that (especially that they were quality replacments), its looking like its time to replace the injectors and pump (pumps at least 125k old and most likley 226k), little earlier then I was hoping for but... (was hoping to wait untill after my last race of the seasson...this weekend)
