IM HOPEING SOMEONE CAN TELL ME HOW TO GET AIR OUT OF MY OIL SYSTEM AFTER REPLACING HEAD GASKET. ON A 2004 DT466E. RUNS BUT WHEN YOU PUT IT IN GEAR IT HAS NO THROTTLE.
These injectors need so much oil pressure that it will run like crap til it gets the air out- which for the oil, shouldn't take long at all. Not sure I would be looking at the air in oil as an issue here- unless you have a high pressure oil/fuel rail end plug leaking or something, which should be making a big mess.
Is the warn engine light on? Was everything hooked back up properly? I'd be checking wire harnesses real close.
The procedure after installing injectors is to prime the fuel system until you have a hard pump and crank for 30 seconds with the cam sensor disconnected. Let the starter cool off and repeat priming and cranking two more times. Hook up the cam sensor and crank to start. It's pretty rough at first. I like to move the truck/bus outside and get it headed downhill to help purge all the air out of the system. Then I drive it for 10-15 minutes. Usually it's running pretty smooth by then. Clear the codes. If it isn't running well, you have other issues.
And turn your caps lock off......
If it doesn't fit, FORCE it. If it breaks, well, it needed replacing anyway. Pullin' wrenches for 45 years.
This sounds obvious but do you have the correct oil level? I know you can get air in the oil if you have too much oil in the crank case. The crank will whip the oil up into a lather.
