More issues 04 H.O Head gasket?
I had fuel gelling issues over the winter and now I think its something worse.. The truck was stumbling on takeoff. I took it to a guy who hooked it up to a computer made for my truck. Checked all pressures, voltages, injectors. Used the computer while driving.. Everything was fine. He said it sounds like water in the fuel. I dropped and drained the tank. New fuel filter. New lift pump about 10k ago. 140k on the truck.
They symptoms- Stumbles occasionally when starting out. The idle has become strange.. Kinda a looping.. Not the typical "Never miss a beat idle" The idle seems rough at times almost stalling rough (But never stalls) I noticed my overflow bottle was empty (Changed the water pump about 15k ago) and I know the level was correct. I refilled the overflow again two weeks ago. Now its empty. No leaks on the ground but I did catch a wiff of antifreeze a couple weeks ago. The truck seems to be blowing white smoke under hard acceleration. My boost pressure seems to be ok 22psi (Its an 04 305/555 six speed) I am gonna have a leak test done tomorrow to see what is up. What do ya think it could be??? Head gasket? Leaking between cylinders? Suggestions??? |
Injectors were done when? Possible head gasket!

That's alot for stock injectors without a 2 micron filter but some have had great luck!
Pull the capoff and see if there are any bubbles in the coolant. Pressure test the system to find any external leaks. The coolant is going somewhere and a leak into a cyclinder is possible. Let us know what you find! |
Have you try turning your key to see if you have a cods on it ?? ASK a cummins dealer ??

Had it tested today. It seems that the fuel pressure regulator is not functioning correctly.(I think that is what its called) The regulator is connected to the high pressure pump. The voltage was fluctuating out of spec along with rail pressure fluctuations. They didn't have one but it was ordered. I will post after it is installed and see if that does indeed fix the problem.

That would be cool!

Fixed!!!
It was the fuel pressure actuator that mounts to the high pressure pump.. $175 and five minute to change |
