Yeah, you just remove cambelt and turn cams, then put belt bk on and tension. Spin over a few times by hand and check its all in time still..that's if the cams are in time with each other, but out of synch with the bottom end.. If, say when you turn the cams round, and 1 inner dot is in the right position, and the other isn't, you'll have to loosen off the cam caps, remove cams, move whichever 1 needs to be, then keeping chain tension lower them bk in and tighten..you have to torque the cam caps with a torque wrench, and pay attention to the way round the caps are etc etc. Basically check everything a million times over before you seal the rocker cover and replace manifold etc, be systematic/ methodical... If you can't, get someone round who knows what they're doing!!
