losing power...grey smoke on start/acceleration

[jeramicox76]

This is my first diesel so i am new to this. I have a 2000 f250 7.3 edge evolution straight pipe lifted 33s. since i put the edge on i have noticed a slow decline in power as well as the smoke going from dark black to more of a grey color, also get a little blue smoke on cold start up. any help would be appreciated...thanks

How is your fuel filter?

i checked the fuel filter and its dark grey...almost black. i have one on order to replace it. cold start this morning it smoked for about 3 min....first blue then grey,smelled like fuel. any ideas....could the edge be wearing out the engine...i run it on 3 with -2 timing.

The smoke and smell are not out of line for a cold 9 year old motor if it cleans up as it worms up. The loss of power is what is saying something is going wrong. The good news is that plugged fuel filter is the number one reason for power loss in a diesel and it's cheap and easy to replace. The other simple thing to fix that can rob power on a Powerstroke is the wrong type of motor oil or old worn out oil that will foam up in the high pressure oil pump (HPOP) and not fully cycle the injectors. Oil change with the right oil is the fix for this one.

Check back if it is still down power after this easy stuff.
