What causes oil to run through the intake manifold?
What causes oil to run through the intake manifold?
This issue causes droplets of oil to run through the intake manifold, the intake port, and in the combustion space, which can lead to pre-ignition as well.
What causes poor fuel delivery on an old car?
Before looking at the fuel pump, make sure there is gasoline in the tank.Another reason for poor fuel delivery on older vehicles is a pinhole leak in the fuel line. A good place to start would be to check the neoprene hose connector between the tank outlet and the fuel line.
What happens when fuel injection is not used?
Fuel injection doesn’t really have that function as well. What happens under this low speed, high load situation is you get bits of carbon and soot that break off from the valves and in the combustion chamber which makes its way to the cylinder walls where it sticks to the oil and the fuel that’s on the cylinder walls.
Can You service a diesel engine with no start?
Service opportunities on diesel-powered vehicles are on the rise. If your shop is looking for additional revenue, taking on the oil-burners could be the ticket. But to be successful, you’ll need the right tools and training. How do you approach a familiar no-start or driveability problem?

Is it bad to have liquid fuel in a cylinder?
From what he has learned through dyno experiences, Dickmeyer says liquid fuel in the cylinder is damaging. Many people will mistakenly say that you’re looking for where the fuel vaporizes, but that’s not really true either because vapor is a liquid turning into gas. What you want, he says, is atomization.
Why is the engine oil so critical for start-up?
Why is the engine oil so critical? Fig. 1 on page 38 shows a simple oil flow schematic for the 6.0L diesel engine. In order for the fuel injectors to operate, a minimum of 500 psi oil pressure is required for start-up.
