So my current Emerald K3 ECU wont support the VVT on this engine, so my current plans are revolving around disabling the VVT, but in a manner which means it can be reinstated in future if required.
Unfortunately, its not as simple as unplugging the VVT solenoid and putting an adjustable cam pulley on the existing inlet cam, as you would have oil pouring out of the end of the cam, where the oilways feed the phaser mechanism. So a rather odd idea entered my head this morning.
How about replacing the current inlet cam, with its internal oilways for the VVT, with an exhaust cam from the same engine, i.e. run the engine with 2 exhaust cams?
The exhaust cam physically fits on the inlet side, all the bearings line up etc. Added bonus is that the exhaust cam actually has slightly more duration than the standard inlet and about the same in terms of valve lift.
Is there something obvious I'm missing which means you couldnt do this? I know the original Mi16 ran with the same cam on the inlet and exhaust, so there doesnt seem anything fundamental which means you cant do this in my mind.
