it depends how far you gonna go with it,first way remove top timing chain cover and wind off cam chain tensioner and remove chain then remove inlet manifold and exhaust etc or are you going to replace the chain because if so its a gearbox and flywheel job off,i have just done the gearbox on mine on my drive and tbh its a arse,if your not very handy with the spanners give the head ache to someone else, ok it costs more but if it blows up or something aint right you can take it back for them to repair.hope this helps
