Hi guys
Do anyone know in ultra high detail how the 20v's VVT pulley actually works?
Heard from my mechanic that when released the timing belt the VVT pulley will rotate anti-clockwise. Hence when installing the timing belt - must rotate the VVT pulley clockwise until cannot turn anymore, then align the marks then install the timing belt. Anyone knows about this?
Figuring out a way to make it into adjustable cam pulley retaining VVT.
Side story, another friend installed a pair of adjustable cam pulleys into his 4AG 16v small port - but says no feel no matter what the setting.
Max variance +/- 1 teeth range. Any idea why?
