I had the same problem with white smoke on my HMMWV. I tried everything to
it, add fuel cleaner, new fuel filter, oil change, check water leak into the
block and so on. What finally cleared it was having the fuel injection pump
rebuilt. Not cheap though. Expect to pay $1,200~$1,500.
One little tip I learned from this is if the smoke is white-white then the
chances are that it's a water problem. If it's blueish-white the fuel is
not being burned properly and is most likely caused by the fuel injection
pump not working properly.

Subject: [MV] HMMWV smokes and loses oil pressure downhill
At our museum, we have a HMMWV that's running pretty rough. It
constantly pours out white smoke - at idle, under load, up hill, down
hill, etc. It's been suggested that it probably needs new injectors.
It has good oil pressure at idle - app. 45psi, but when you go down
hill, it drops down to almost zero. When you level out, it goes back up
to 45. According to the dipstick, it has enough oil. Other than this,
it runs great. Does anyone have any suggestions on these?
I haven't done much work on diesels in general, so any advice would be
appreciated.
