for pink crust. mine was leaking from where it goes through the firewall next to the battery because the clamp had slipped off a bit. could also have something to do with the oil cooler iirc and that's a bigger problem but someone else would probably know more about this or you could search for more info. check around the engine compt. for pink crust and try to find where it's coming from.

1. the coolant lines going into the oil cooler (above the oil filter). Those factory spring clamps almost always leak. Check this first.
2. the o-ring sealing the housing for the coolant temp sensor in the back of the head starts to leak. If so, you'll see dried crusty coolant droppings trailing down the back of the motor.
3. bad water pump. You'll see crust dripping down from the weep hole in the bottom of the pump.
4. blown oil cooler (though this will usually result in oil/coolant mixing which you'd probably have noticed by now).
Less likely causes:
1. cracked head gasket
2. cracked head
3. leaky radiator
4. leaky heater core
Good luck!
Cheers,

i'm gonna replace an o-ring or two and see if that fixes it. check out the tech article by BSK if you haven't already.
