alright guys,my dad has a 97 12 valve,stock except for a banks intake manifold.it's been runnin fine until a day or two ago,he said it aint got any power goin up hills.and he said it's blowin white smoke.he said it spits and sputters too.any suggestions?

 

check timing

 

Yup - most likely slipped timing.

White smoke = not enough heat to burn the fuel. Could be the grid heater but its probably too warm for that to be the problem. The problem could also be bad injector(s), worn injector pump, air in the fuel system, and low compression. But check the pump timing first.

 

is this something i can do,and if so,how,thanks.

 

If you have a timing set and know how then yes if not then no

 

Hard for us to answer.

You need a dial indicator, deliver valve socket, magnet, and barring tool:

SP500, Set, Diesel Timing Gauge

You pull #1 delivery valve and measure the amount of lift on the plunger.


If you have to ask - you might need some help

 

your also goin to need to know what pump he has if its an auto its the 180 if its a stick its the 215

 

auto
