Make sure you get new gaskets for the o2 housing and downpipe. The easiest way would probly be to take the radiator fan out (on the left side of the engine, unscrew the o2 sensor, disconnect the downpipe, then get at the bolts from the top or bootom as you can. I have only replaced it myself by taking out the turbo though even though it is not needed. There may be an easier way. I have ever replaced cams though... I had Rick change mine when he was doing the t belt. You may want to take the ones I gave you off the gears and the same with your old ones. Then you can just slide them in and not have to worry about the timing (I think). Never done it before though.
