What does variable valve timing on Ford F-150 do?
The variable valve timing system operates when the engine computer (PCM) sends oil pressure to one or the other chamber of the phaser via cam timing solenoids. Unfortunately, these cam phasers wear and cause various rattles and clicking noises from the engine in 2004 to 2008 F-150 models at low oil pressures, like at idle.
When to check timing on Ford F-150?
For the Ford F-150 to run efficiently the timing needs to be checked routinely during a tune-up. This will ensure the best performance and gas mileage for the F-150. The procedure to check timing for six-cylinder and V-8 engines is basically the same but there are two slight differences.
How many miles could a Ford F150 V8 4.6 L could go up to?
The 4.6L engines I work with are serviced religiously and run well over 150,000 mile in SEVERE service. The car wears out long before the engines do. 13 people found this helpful. My 2008 F150 has 344,000 miles on it with the 4.6 V8 engine. It is service regularly and driven daily. The transmission is also original.
What kind of timing does a Ford V-8 use?
The new 3-valve engine will be Ford’s first modular V-8 to use variable cam timing, which allows engineers to optimize intake and exhaust valve actuation across the engine speed range. It is the industry’s first mass application of dual-equal variable-cam timing, which shifts the intake and exhaust valve timing together.

When did the Ford F-150 start to idle?
Raybuck Auto Body Parts warns that 12 th -gen F-150s (2009-2014) often start to run and idle roughly. This was particularly problematic for the 2010 model year, which is on our list of F-150 model years to avoid. The rough idle wasn’t due to the turbocharged EcoBoost engine—that didn’t come until 2011.
When did the Ford 4.6L engine come out?
Built between 1990 and 2014, the Ford 4.6L architecture was one of the first engines to be part of the Ford Modular family. The first vehicle to be powered by this engine was the Lincoln Town Car in 1990.
What happens to the oil in a Ford F150?
Oil keeps your engine lubricated to perform its best. When it gets old it starts to break down and lose its lubricating properties. Once this happens, parts in the engine will begin to overheat due to the friction and will eventually lead to the engine seizing.
