I don't disagree with what you guys are saying. I would be saying the same thing. I am going to try several things. Tighten head bolts, new gasket, block sealant. However between these test, I want to be able to get any water out that slips by out of the oil pan without removeing the pan. Like I said before, I have not noticed the water level dropping in the radiator but I want to monitor it close to make sure I have the problem fixed. If fact, I check my water level regularly and I don't remember adding water all last year. I just hope it is not a cracked block.
