1999 Brighton Wagon, EJ 22, Auto, Air, 175,000 kms. : I posted earlier with the car's symptoms, and by everyone's opinon it looks like I need the head gasket replaced. I'm going to have this done next weekend. What else should I get done while this procedure is performed? The timing belt, alternator belt and oil seals were done at 169000 kms when I bought it earlier this year. I'd hate to be saying "I should have..." after it's been done.

Thanks for your input.

Replace oil separator with a metal one if it currently has a plastic one. Check the geared/toothed idler while the timing belt is off since that seems to be the one that goes bad first most often.

How about water pump? It is cheap to do when it is in that state.
