Its so tight on that side of the engine, it's going to be so difficult to get to the timing chain fully. Cam covers off will be the first thing to do, which means removing the inlet manifold, labour intensive just that. The oil will need dropping and the timing chain cover taking off, this will mean removing quite a number of items including the crankshaft pulley, auxiliary belt and tensioner.
It may be quicker just to pull the engine, for much easier access though. Hoists can be rented from tool shops.
Good luck!
