How does a 6.0 powerstroke work

Failure to do so can cause the injector not to be fully seated, which can lead to compression leakage in the fuel system and catastrophic damage. Once removed, be sure the compression seal on the injector tip comes out with the injector.

Also, check for any signs of fuel contamination at the injector fuel inlet screen. If contamination is found, the source must be located or the replacement injectors will be sure to fail.

To install the fuel injector, assemble the clamp and bolt to the injector, being careful to note the orientation notch. Lubricate the O-rings with engine oil, install them in the cylinder head, and torque to specifications. The last step before installing the valve cover is to snap the PCM injector wiring to the injector pigtails. When trying to make the connection, the pigtail may get pushed back into the cylinder head. To help prevent premature injector failure , an updated spring is available that boosts the fuel pump pressure an additional 10 psi.

The added pressure ensures that there is adequate fuel in the injectors at all times. Pockets in the fuel system can cause the injector end to break. Watch how to replace the fuel pressure regulator on a 6. In some instances, this is warranted. In others, not so much. In our opinion, maintenance is key if you want this engine to last. By releasing the 6. Thanks to the success of the 7.

In fact, midway through the 6. With both its oil cooler and high-pressure oil pump integrated into the block, the 6. Also different from the 7. Nearly everyone knows that 6. Many factors can contribute to a blown head gasket, but it all starts with the head bolts—the type and the lack of them. Torque-to-yield head bolts are nothing new in automotive engines, but once a TTY fastener stretches beyond its yield point, it becomes permanently elongated. This translates into a loss of clamping force.

The 6. Despite powdered-metal connecting rods getting a bad name with the 7. Granted, the 6. In the diesel aftermarket, the 6. With four overhead valves per cylinder, the 6. An aluminum rocker box mounts to the top of each head and fastens in place courtesy of the head bolts.

In addition, the rocker box provides the mounting point for all of the rocker arm fulcrums and provides the connector pass-through ports for the injector and glow plugs.

Bulletproof kits for a 6. Installing a Bulletproof kit is very labor intensive, so expect to pay a couple thousand in labor costs. While the 6.

Our best advice is to look for a late model truck or a 6. Many of these problems occur early in these trucks lifetimes, so many of the 6. If you are considering performance modifications, you need to replace these studs. The addition of a tuner alone can cause cylinder head pressures to rise beyond the capability of the TTY head studs, ultimately causing head gasket failure.

TTY studs cannot be re-used and must be replaced after being removed from the engine. Aftermarket head studs from ARP are a must-have for your 6. The stock TTY head studs can last a while under factory conditions. Because of the layout under the hood, changing the head studs on the 6. It can take a long time, even for an experienced diesel mechanic. Expect costs of a couple thousand dollars after parts and labor.

The FICM supplies 48 volts to the two solenoids that control oil flow to the fuel injector. Excessive heat from the engine and vibration can cause the FICM to overheat or fail. Cold starts impact the FICM negatively by causing excess voltage to be drawn. This can damage the capacitors in the fuel injection control module.

You should replace factory fuel injection control modules with aftermarket counterparts. They are better at dissipating heat and more reliable. Reputable FICM rebuilding companies also typically offer a warranty on their products.

Should an issue arise, they will send you a replacement FICM. Aftermarket FICMs also come available with custom tunes, allowing you to increase horsepower by adjusting fueling. Many of the problems found on the 6.

These trucks require the oil to be cooled significantly more than other trucks, resulting in Ford equipping the 6. Over time, sand and other large particles can clog the small passageways of the Oil Cooler, leading to EGR Cooler failure.

You can identify faulty oil coolers by comparing engine oil temperature and coolant temperature. Has the EGR Cooler been removed or replaced? Has the Oil Cooler been replaced? You can look down beside the intake manifold on the passenger side of the truck, you'll be able to see if the EGR Cooler has been removed and it's being bypassed.

This is one of the first things to check as they will inevitably cause issues. If the EGR is cracked, you'll be able to tell because the truck will likely be puffing white smoke at idle when the EGR valve opens up.

This is because the truck is now burning all the coolant that's leaking into the intake manifold. It should sound like a nice electrical buzzing noise from under the hood. If you're hearing a more erratic clicking or the odd click here and there than the injectors may be getting weak. This is fairly common, these trucks are known to chew through injectors every ,,kms. If the injectors have been replaced, ask for receipts and find out what injectors were installed as there is no shortage of cheap 6.

Remember, when it comes to injectors, you get what you pay for. If you're after a 6. If you feel confident that everything above has been completed and completed well, it might be a great buy. They can be a blast to drive and they sound amazing with some small modifications, but we often see 6.

My personal recommendation would be to find a 6. You may find a gem that runs forever and never gives you grief, but you always run the risk of finding one that is always needing new parts.
