On the other hand, if more power is needed, the cam phaser will move the camshaft affecting the position of the cam lobes and, of course, the speed and timing of the valve opening. The connecting rods were fracture split powdered metal construction. It is not a major issue as it is usually corrected with gasket replacement. Beginning in 2004, the F-series changed to a 3 valve setup, followed 1 year later by the Expedition and Lincoln Navigator. You should check out Tuning the 5. Ford technicians will diagnose the problem, identify misfiring cylinder s , and replace the spark plug and coil where needed. The highest output version of this engine was in the that included a supercharger and was capable of 550 hp along with 510 lb-ft of torque.
This engine, along with the several other V8 and V10 engines, are a part of what is called the , which is essentially all of the V8 and V10 overhead cam engines. This noise usually points to a damaged, failed, or destroyed cam phaser which would affect almost all other moving pieces in the engine The only reasonable solution is replacement with an all-new unit. The valvetrain for this engine did vary over time, although all engines used overhead cam technology. Would like to see better quality rubber floor mats standard and leather seat guards for those who practically live in their vehicle. You can hear a lot of knocking noises on acceleration, cold startup, or when you let off the throttle.
After Ford recognized this problem, they offered a slightly redesigned replacement part which is not in direct contact with the steel frame. As its surface is exposed to the elements, salt, water, and dirt build up on its aluminum casing and cannot be washed away as it is in contact with the steel frame. Therefore, viewer agrees to release, waive, and discharge FordTechMakuloco or anyone affiliated with FordTechMakuloco, from any and all liability, claims, demands, actions, and causes of action whatsoever arising out of or related to any loss, damage, or injury, including death, that may be sustained by the viewer, or to any property belonging to viewer, regardless of whether the loss is linked to the use of the contents of this video, or otherwise and regardless of whether such liability arises in tort, contract, strict liability, or otherwise, to the fullest extent allowed by law. Specifically, on a F150, it is located above the spare tire attached to the frame. Ignition System Issues My research included all versions of the 5. There is a potential that this could cause an engine fire! The situation is slightly ironic since earlier 2 valve 5. Will sometimes get 11 empty.
They re-secured the cover with a different type of safety connector, and then re-started the vehicle. The spark plug issue has just bitten me, now I have a 10,000 dollar peice of steel in my driveway because I am not paying 5400 and some change to fix a problem that should be recalled, the plug gettting hit by the piston or shooting out of the hole can be very dangerous by allowing fuel to come in contact with hot engine or electrical spark therefore starting a fire, this problem has been an ongoing issue and yet nothing is done I think a recall should be placed for the issue. Other 4 valve applications were primarily used in sports cars. Although this engine has some issues, as most engines do, they have mostly been resolved, and the overall consensus is that this is a highly reliable engine. Eventually, the truck will start to backfire through the intake and even fail to accelerate to over 30mph in severe cases. Reasons for cam phaser failure may be related to excessive wear or failure of some sensitive parts of the cam phaser.
If you have any doubt of excessive oil consumption, you should first check oil pan for leaks and damage. With extended time the corrosion would eat a hole through the aluminum housing and expose the electronics to water and road grime. It seems that problems with the ignition system did affect all versions at one point in time. In the first place, the problem happens because the fuel pump driver module is directly attached to the steel frame. Over time, vibrations, salt, and water do irreparable damage to the casing and dirt enters the driver module causing short circuits and making permanent damage to the smart junction box. It's all down hill from there.
While it is not an overly powerful engine, the 5. Due to the design of the combustion cylinder, essentially these engines are semi-hemispherical, the plugs needed to protrude down through the head to the combustion chamber. As this problem progressively gets worse, when engine is hot and you let off the throttle the engine may loose the ability to maintain engine timing causing it to run rough and rattle like crazy. In some applications this engine was paired with a Supercharger for some real power, 550 hp. These deteriorate with age and weak spots in the rubber can cause the spark to jump to the plug well instead of the spark plug.
This led to extreme corrosion build up on the module. As others said a little underpowered. Though this is over the recommended tow weight of 8,900, by nearly 2000 lbs. Entered traffic lane and began lightly braking for approaching signal. Head and Block Construction The primary construction of this engine is a cast iron block to be paired with aluminum cylinder head. The majority of people also seem to be happy with the reliability.
Especially on light acceleration most noticeable to the driver with the window down while pulling forward in a drive or down an alley. Generally at the Ford dealership, we will diagnose the cylinders with the misfire and replace the plug and coil for those cylinders. The contact stated that a spark plug failed, causing gasoline to blow into the engine. Here's a recent thread with my '04 I just bought. In the worst case scenario, spark plug fragments parts of metal or ceramic could end up in the cylinder. Spark plugs are a whole different animal on this engine. When you hear a 3 valve 5.
