Hi all, just wondered if anyone knew anything about the VVT system on the 1.2 engine? I’m guessing that oil control valve on top of the engine does something to the crankshaft?

I can't add, but can you tell when the vvt starts to work, our Mazda you can really feel and hear when it's working

All VVT’s work the same
They use oil pressure to adjust the cams to various load conditions by retarding or advancing valve opening times-This gives optimum mpg/emissions and performance criteria
