Replacing the camchain at the moment myself, I have the cams out and just waiting for the new chain to arrive.
I guess the next step will be to split the existing chain, tie the new one on to it, feed it around the crank turning the flywheel, and then join the new one together with the rivet link.
Once thing thats puzzling me though - how do you know when the engine is at TDC on the no.1 cylinder after all this turning of the crank without the cams and before you re-install them?
Surely you don't just re-install the cams without the engine at TDC on no.1
