What happens if a cam phaser goes bad?
When a cam phaser goes bad, the Variable Control Timing (VCT) solenoids would be destroyed, and the engine control unit (ECU) would no longer be able to control the phasers. If not attended to, it can lead to valve timing problems which would eventually damage the engine.
What does a camshaft phaser do?
A “cam phaser” is just an adjustable camshaft sprocket that can be turned by means of a computer-controled servo. Rather than just setting a certain amount of advance or retard, the computer can advance the cam or cams at low rpm to enhance driveability, and retard the cam or cams at high rpm for more horsepower.
What is a cam phaser solenoid?
The VCT solenoid is an electronically controlled valve that is determined by the PCM. Depending on this VCT solenoid position, it allows oil pressure to enter the phaser or keep moving to stop camshaft timing.
How does GM cam phaser work?
GM’s cam phaser is a specially designed, computer controlled cam gear that has the ability to adjust camshaft position while the engine is running. How does it work? The engine computer controls a solenoid that adjusts the oil flow into, and out of, a series of chambers inside the cam gear.
How can you tell if a cam phaser is bad?
Typically, worn phasers create a loud and rough idle. Often, a knocking noise is heard. In some instances, the noise is not due to wear in the phasers but rather low oil pressure due to cam bearing wear in the cylinder heads. If that is the case, the heads may need to be replaced or machined.
How much does it cost to fix cam phasers?
Replacing cam phasers is not cheap. You can expect to pay anywhere from $800 to $2500 to get the job done by a professional.
Is it worth it to replace Cam phasers?
Replacement of the phasers alone is not the correct repair, all of the cam followers are to be replaced as well. If the phasers were replaced improperly then it could possibly cause engine damage, but it also would not run right once repair was completed.
How do you stop cam phaser problems?
The sure fix to phaser problems is to lock the variable cam timing by essentially turning the phaser into a fixed timing gear. The WMS Cam Phaser Lockout kit will solve the phaser issue permanently.
Why do Ford cam phasers go bad?
The reason cam phaser go bad are incorrect oil n weight, low oil pressure through them caused by damaged cam journals or the solenoid. It’s metal against metal inside of them.
What causes cam phaser knock?
The cam phasers are used to advance and retreat cam timing. This is oil pressure controlled by variable cam timing solenoids. If the pressure drops due to a malfunctioning part, it will cause a knocking noise. Basically, a locking pin keeps oil thin at idle, and the problem goes away when you start driving.
Will bad cam phasers throw a code?
It will go into safe (or limp) mode, which will in most cases, and stop the engine from going over a certain RPM. It will also throw a code and illuminate the check engine light.
Do VVT sprockets go bad?
Since the timing chain can go bad and will need to be replaced, it is important to be able to recognize the symptoms and have it repaired before it fails completely. Signs a timing chain needs to be replaced include: Later model VVT applications will generate engine codes and check engine lights prior to engine rattle.
What year did Ford fix the 5.4 cam phaser?
2004 – 2010 Ford F-150 (5.4) It ranged all the way from the 2004 F-150 after its redesign, all the way into the next generation until they moved away from the 5.4, instead moving to the 5.0 that replaced it in 2011.
What years did the 5.4 Triton have problems?
Most of the most common problems developed with the 2004-2013 3 valve engine but some problems spanned all engine generations. The most popular issue but easiest to fix, is the ignition system. The 3 valve 5.4L Triton contains a coil-on-plug design. Each cylinder has a separate coil that fits onto the spark plug.
How many miles can a 5.4 Triton last?
The life expectancy of the Ford 5.4 engine ranges between 150,000 and 300,000 miles. However, it still all depends on how the vehicle driver or owner maintains the engine. A truck carrying heavily loaded trailers with a 5.4 Triton engine can still certainly run great at 250,000 miles.
What year did Ford have cam phaser problems?
2005
What is the best year for the 5.4 Triton?
2009-2010 Triton 5.4L With 300 horsepower and 365 lb-ft of torque, the Triton 5.4L is one of the most reliable F150 engines.
Is Ford 5.4 a good engine?
The 5.4L V8 Triton is a solid all-around engine. Ford used this engine in a lot of flagship vehicles for a long time, including high performance cars like the Ford GT. However, every engine is prone to a few common problems and this holds true for the Ford 5.4L.
