popping

Recommended Posts

ok...on my 93 dodge diesel i have a popping noise when it is revved up with no load. at about 1,000 rpm it starts popping real bad and blows a shit load of white smoke. my dads and my brothere 1st gens do not do this. what could be causing this? i have my IP turned up, the truck has 187000 miles on factory IP, stock turbo, stock injectors, pretty much all stock.

White smoke is raw fuel or water. I am betting fuel. Injector(s) could be getting weak. Easy way is to open the injector lines up one at a time and try to duplicate the problem.

Popping through the intake or exhaust?

I have heard it through the intake and it was loose valves. I think the book says to adjust every 30,k and about 50,k in practice is ok......
