Don't worry about it man, I was just giving you a heads up because Zilvia can be a little rough on new members sometimes.

Sadly Nissan will do nothing to help you out on this one. It was just considered a recommended service and was optional (I think you even had to pay to get it done). Draining your oil won't get much if any of the broken guide out because of the baffling and such inside the pan, not to mention the fact that some of the pieces are probably too big to fit through the oil drain hole.

There really isn't any easy way out of this situation and if you continue to drive the car without the guide the chain will eventually eat through the water jacket in the timing cover and ruin your engine. There is a step by step guide for replacing the timing chain in the FSM so just follow that and you should be good to go.
