I was out there rolling around on the cold ground anyway (exhaust came apart right before the front muffler), so I thought I'd take the cam belt cover off and trace the oil leak. There was no oil coming from behind the pulley that I could see.
It looks like it's coming from somewhere around where the water pump meets the engine on top of the pump, but there's no trail, maybe because of heat. The other thing I noticed is that when the engine is running the water pump is making the typical "Fat Lady is singing" noises. So I'm going to replace it anyway.
My question: do Volvo water pumps have lots of lube in them? Could this just be escaped lube from a bad bearing? I've replaced a few water pumps over the years (beer cases make good gasket material in a pinch, btw), but never saw one hemorraging oil before.
In any case, I'm going to go find a replacement tomorrow and put it on. Anything tricky/different doing about a 230 water pump, other than paying $100 for one?
