Do any of the water pump or timing cover bolts go into the water jacket on a poly? I don't think I used any sealant on any of them back when I rebuilt the engine and I'm noticing small amounts of coolant on the little shelf at the bottom of the timing cover. Assuming that I do need sealant on those threads, do they have to be dry or can I just drain the coolant, remove the bolts and use sealant? What sealant should I use? Man I hope I can get this thing back together in time for the nats ... Thanks in advance, Brian
