Waterpump leaking or blown headgasket or both?

[khartley]

Alright, well my 94 AWD has been acting up a little lately, a very small idle surge, leaking a little antifreeze, and wouldn't boost higher than 9 lbs, when it usually did about 12.5. I changed the oil today, and when I removed the filter, there was a tiny amount of froth in it, I'm not sure if that would be antifreeze or not, it had been running for about 5 minutes just before I changed the oil, and there was no froth from the oil in the pan. So I tightened a few bolts around my intercooler piping and drove it hard, with no change in boost. I then hooked up my mbc and tried again and it was back to normal with boost - right at 12.5. But after boosting about a half a mile, white smoke started pouring out of the hood, but it was not overheating. I popped the hood, and on the right (drivers side) of the block, right by the timing belt, in the area of the exhaust manifold, I could tell where there was some antifreeze leaking out and causing the cloud of white smoke, and it was dripping lightly under the car as well.
So is it

A. headgasket
B. waterpump
C. both
D. neither

?????
thanks guys

Ok, I messed with it for a while and I let it idle and revved it up a few times and checked the dipstick with no signs of froth. I turned it off after a while of doing that and looked under the car, and there was antifreeze dripping off of one of the braces, the one by the oil filter, and it was dripping out of a black hole kind of by the filter. Is this part of my waterpump? And is there any way that the antifreeze dripping that low can be blown by the fans onto the head, right by the timing belt cover, just above the exhaust manifold?
