Easy enough job to do, did a quad cam turbo one yesterday in around 3 hours start to finish.

Take the expansion bottle and fans off and you have plenty of room, no need to remove the radiator.

I very lightly clamped the two n/s cams together as they are on the rock when you time it up at TDC, the two on the o/s can move very easily when you have the belt off so be sure to mark it up well before taking the belt off.

Also be sure to compress the hydraulic tensioner very slowly and if there are any signs of oil dampness coming from it fit a new one !
