It is inherent that all cam phasers have a certain oil leak rate. Variable Cam Timing (VCT) phasers require proper oil pressure to function correctly. The check engine light is on, on my 2008 Expedition due to P345 & P349 codes (cam position sensor bank 2) I have changed the sensor, but the light is still on (will stay off during the first start up after clearing the errors and can be run for any distance without the light on but will immediately come. The engine's computer controls solenoids that. Engine oil is pressure fed to the phasers through passageways in the cylinder heads and cams. I have an 18 raptor and he said it would take 3 days in shop.COMP Cams#5761 Cam Phaser Limiter Kit for Chrysler 5.7L, 6.1L, 6.4L Hemi Cam phasers are specially designed, computer-controlled cam gears that automatically optimize camshaft timing based on engine RPM. Replace all 4 phasers, check chain, replace tensioners and only replace solenoids if they need it. I chose to limit them (rather than lock them completely out) in order to mainta.11. $5.00 coupon applied at checkout Save $5.00 with coupon.To begin Stage 2, I wanted to demonstrate how to limit Ford's 3v cam phasers.

While VVT systems can provide benefits in terms of performance. Cam phasers are components that control the timing of the intake and exhaust valves in relation to the engine's crankshaft rotation. Many new Ford engines feature Ti-VCT, including ones used in the 2011-2015 Mustang, 2011 Edge and Edge Sport, 2011 Lincoln MKX, 2011 Fiesta, 2011 Explorer, 2011-2016 F-150, and 2012 Focus.A cam phaser lockout kit is an aftermarket solution designed to eliminate the variable valve timing (VVT) functionality of an engine's cam phasers. Some Ford Ti-VCT engines use BorgWarner's Cam Torque Actuation (CTA) which utilizes the 'existing torsional energy in the valve train to rotate the camshaft' instead of traditional oil pressure driven cam phasing. This allows for improved power and torque, particularly at lower engine RPM, as well as improved fuel economy and reduced emissions.

Twin Independent Variable Camshaft Timing ( Ti-VCT) is the name given by Ford to engines with the ability to advance or retard the timing of both the intake and exhaust camshafts independently, unlike the original versions of VCT, which only operated on a single camshaft. That motor has a single cam per bank, so it is dual-equal variable cam timing. The 6.2L V8 introduced in the 2010 SVT Raptor also uses VCT. In addition, the 1.7L Zetec-S engine found in the European Ford Puma was equipped with variable camshaft timing. The 2002-2004 SVT Focus ( ST170 in Europe) also featured VCT, but on the intake camshaft of its modified version of the 2.0L Zetec engine. The 2.0L Zetec Inline-4 used in the 1998-2003 Ford Escort ZX2, Ford Contour, and 99-02 Mercury Cougar used VCT on the exhaust camshaft. VCT is used in Ford's Triton 5.4L 3-valve V8 engine, the Australian Barra 182 and 240 Inline-6s, and Ford's 4.6L 3-valve V8 engine used in the 2006-2010 Ford Explorer and 2005-2010 Ford Mustang GT. VCT on the intake camshaft is used primarily for increasing engine power and torque as the PCM is able to optimize the opening of the intake valves to match the engine conditions.

(Engines that have VCT on both camshafts are now designated as Ti-VCT.↓) The use of variable camshaft timing on the exhaust camshaft is for improved emissions, and vehicles with VCT on the exhaust camshaft do not require exhaust gas recirculation (EGR) as retarding the exhaust cam timing achieves the same result. The PCM adjusts the camshaft timing depending on factors such as engine load and RPM.įor twin cam or DOHC engines, VCT was used on either the intake or exhaust camshaft. The phaser cavity changes the valve timing by rotating the camshaft slightly from its initial orientation, which results in the camshaft timing being advanced or retarded. The powertrain control module (PCM) transmits a signal to the solenoids to move a valve spool that regulates the flow of oil to the phaser cavity. These oil control solenoids are bolted into the cylinder heads towards the front of the engine near the camshaft phasers. It uses electronically controlled hydraulic valves that direct high pressure engine oil into the camshaft phaser cavity. It allows for more optimum engine performance, reduced emissions, and increased fuel efficiency compared to engines with fixed camshafts.
