I would also add the RMS and a Waterpump & maybe a low temp Thermostat whilst he's under there!

Isn't there something with the tensioners / variocam that should be addressed while you're down there?

NO! Don't open up the engine unless it's broke--it really opens a can of worms when you do.

Couple of thoughts

1. Drop the sump and check to see if you have debris from the internal timing chain rails. If so, fixing the IMS will be a short term preventative. A failed chain rail will destroy the engine

2. Variocam chain pads are a wear item that can be replaced by taking off the valve covers - no need to open up the engine. The parts are cheap.
