What happens when injector cups go bad?
What happens when injector cups go bad?
The injector cup seals the cooling system from the injector inside the cylinder head. When the injector cup fails, you will no longer have a seal between the fuel system and the coolant system. Because of the higher pressure of the fuel system, the fuel goes into the coolant.
Can you drive a 6.0 Powerstroke with a bad injector?
you usually cant drive it after the bad injector melts your piston.
How do I clean my injector holes?
Place the cylinder at TDC. Clean the bore but do not dump carbon into the cylinders, best to remove the GP and if major amounts of carbon are found, then use a vacuum to clean/suck debris out through the injector or GP hole.
How long does it take to change injectors on 6.0 Powerstroke?
replace injectors takes about 4-6 hours , easiest way to do it, pull valve covers, remove gasket and disconnect wires from injectors and glow plugs. remove 8 mm bolt at lower injector. pull glowplugs.
What causes diesel fuel in coolant?
The fuel pressure from the injector rail cast into the head (small hole to the left of the arrow) is far greater than the pressure in the cooling system. When a crack occurs, diesel fuel easily passes into the coolant. It may take a couple hours for the pressure to show on the gauge if the crack is really small.
What happens if the injector Cup fails on a 6.0L diesel?
Injector cups are a very vital part of the internal workings of a Powerstroke diesel engine, whether it is a 6.0L or a 7.3L. The injector cup seals the cooling system from the injector inside the cylinder head. When the injector cup fails, you will no longer have a seal between the fuel system and the coolant system.
What causes a diesel injector to fail on a Ford PowerStroke?
These injectors drive diesel fuel into the cylinder where it is oxidized and ignited, creating the legendary earth-moving power the Ford Powerstroke is known for. The first of the three basic types of Powerstroke Diesel Injector failure is normal mechanical wear and tear.
How does the tool get pulled out of the injector Cup?
When it is bottomed, it is bottomed. Once the tool is driven into the injector cup, the outer nut is tightened down against the retaining ring and this is how it gets pulled out. You have to use a deep ¾ inch socket, 19 mm. Out she comes.
What causes a dead Miss on a 6.0L Powerstroke?
As trucks equipped with the 6.0L Powerstroke get older, this type of diesel injector failure has become more and more common. The problem is that over time, the moving components inside the injector assembly wear and degrade and are unable to perform their function without causing a dead miss.
