This can cause the engine to run rough, stall, or have a no hot start condition, often with trouble codes P2284, P2290 or P2291. Remove the 3 nuts holding the bracket to the top of the heater core with a 10 mm deep socket. Archoil is amongst the leading manufacturers of stiction eliminating oil additives, and we use their religiously. So i bit the bullet and went to local Ford dealer and got one today. Signs of a bad or sticking stiction injector are hard start, rough idle, black or gray smoke. The best thing you can do to prevent failure is maintain proper fuel quality by means of an additive if necessary and keep your engine oil changed regularly.
Today the diesel is running as it should be it was a bad injector all along. The unison ring could also be cracked, but this often happens when someone tries to pry the ring off the center housing. If any interference or clearance issues are detected, continue cleaning. If you forget this step or accidentally remove your reference line while cleaning, we'll show you how to install the unison ring in the correct position without a reference line. The vanes can be opened or closed to allow the engine to build and maintain proper boost levels. The solution is to install aftermarket head studs, which offer more desirable material properties and evenly distributed clamping force. A mechanical failure will not show any codes pointing directly at this solenoid.
Electronic diagnostic equipment can be used to verify whether or not the pump is operating within spec. Ultimately, you'll want to seat the housing until the groove is eliminated and the two sections are fully seated; do not neglect to check for binding of the turbine wheel during this process. Now Ford recommends cleaning the turbocharger to restore performance. On all cars it is a simple plug with 2 wires connecting to it. You may skip these steps if your unison ring has a reference line that positions it correctly within the turbine housing. If you look at the air filter box on engine side you will see a black square plastic box that is on the side of the air filter box and has a round plastic hose on it that then goes to the engine.
If the valve sticks in the open position, a loss of power may be experienced. If the solenoid fails, you will have similar symptoms as a stuck unison ring. If ignored this can cause serious engine damage. Another common failure point is the. You may also consider investing in an to remove particulates from the engine coolant. Oil Cooler The Oil cooler is the cause of most the 6. Torque bracket retaining bolt to between 15 and 18 ft-lbs.
When the Oil cooler is not restricted the coolant temperature and oil temperatures should be within a couple degrees of each other, anything above a 15 degree difference indicates a problem. You will need to spread the connect tab away from the sensor body to unplug the sensor. Note: This article is not to discredit the 6. Do not be afraid to reapply penetrating fluid and let the parts soak. After the scan, the scanner will display one or more alphanumeric codes, which may be looked up in a reference book that accompanies the scanner if the scanner is one that does not display the summary of the code on its screen. For turbocharger installation procedures, see:.
Verify that unison ring moves freely around the flange on the bearing housing below the turbine wheel see image. You may also consider investing in an aftermarket coolant filter to remove particulates from the engine cooling system. The key way slot in the ring where the valve arm rides can also wear becoming too large. Both require an 8 mm socket - the solenoid must be a 12 point socket. . Im surprised it was one bad injector. The way that it sits on the center housing makes it a culprit to stick often.
I might not get a injector back. Repeat the procedure until a gap begins to form between the turbine housing and flange, rotating the turbocharger after a few taps and working 360 degrees around the housing. There are many claims that the early 6 liters were the most problematic, though it is debatable if there truly is any significant correlation between model year and reliability. Torque the turbine housing clamp to 160 in-lbs, then loosen and re-torque to 50 in-lbs. The high pressure oil is used compress fuel in the injectors. I think I finally got the issue figured out and the parts will be here tomorrow.
An oil cooler failure is suspect if oil is present in the coolant or visa versa. Many class action lawsuits have resulted from the numerous problems that arose frequently. Will cause a flag in the computer and turn on the Check Engine Light. Depending on where it seizes, you could have several different symptoms. This can result in oil cooking in the turbocharger, and has been known to cause complete turbo failure in some instances.
Unplug the electrical connector from the sensor. After removing the solenoid connector, measure the resistance across the two pins. The valve is connected to a unison ring, which is connected to all the vanes. A common perspective, in which we support, is that the 6. It is a two wire sensor that plugs into the intake tube via a rubber grommet.
I get that the spring ups the fuel pressure, but by how much, whered ya get it, etc. Sometimes, however, a malfunction in this little instrument can lead to big problems, usually resulting in very poor engine performance. There are a number of options out there and many of the rebuilds are of higher quality than the originals. Output was 325 hp 242 kW at 3300 rpm and 560 ft·lbf 759 Nm at 2000 rpm, but as of 2005 that was increased to 570 lb·ft 773 N·m at 2000 rpm. Before performing the test, allow the vehicle to warm up for several minutes - results may be most accurate on an engine at operating temperature. Blown head gaskets are extremely common in modified engines. This includes, but is not limited to vehicle damage and personal injury.
