Is there an altitude sensor? White smoke in Mountains.
85 6.9 4 speed manual, compression front 5 are 400 back 3 are 380
When towing 8000 pounds above 3500 foot elevation up a grade it starts blowing ALOT of greyish smoke even though I only seem to be giving it around 1/2 - 3/4 throttle in 3rd (4 speed manual).
I am passing big rigs just fine but it got up to 1/2 temp on the dial and the overheat light came on.
And now I noticed that its blowing lots of white smoke when the engines cold especially idling or decelerating and sometimes when giving the gas starting up a little hill after coasting for a while from around the 8000 foot elevation to around the 3500 elevation.
When I get down below 3500 feet its fine and blows little or normal smoke when floored and the smoke looks just like any other diesel. But by that point the engine is at normal operating temp.
I changed the fuel water filter and just reciently had a professional install a new injection pump all new injectors added the 7.3 style fuel water filter with lower threaded bleeder, and all new glow plugs
Thanks everyone...
