in need of 20v conversion help....

has anyone done this conversion that can help me please.
struggling to sort out what cambelt i need. i have a mk2 16v tenioner (i think) but the belt i have is too wide for the tensioner its self. do i need to chamge the belt????
also need advice on loosing the oil breather pipes if anyone has done this.
would appreciate any help cheers guys

anyone?

sounds like you may have an 8v tensioner, the 16v one is wider. i'm pretty sure the std 20v belt fits the 16v tensioner? issue is spacing the 16v tensioner enough rather than belt width i thought

iv ordered another tensioner now that had the measurement displayed so hopfull this should be fine. yeah i think you have to space it 8mm. cheers
