its on the intake side of the engine i think there about 4 of them so that means that you might have to take off the whole intake ass...

OUCH.. that's coolant problems and a half!

can you pin point the area of the leak?

I just finished RE and RE of the entire coolant system on my bro's 325.. what a pain! it had a leak near the water pump.. but there is no way to see whats leaking till you take it apart.. and shure enough, one of the hoses had a crack in it *mad*
