[QUOTE="Davy Crockett, post: 220846, member: 367"] By hookey You were right , Not sure if that is the extent of the problems of but I pressure checked it with bubble solution and there is an internal crack above # 3 exhaust port. It leaked so bad that I was able to blow the solution right out of the manifold . The first thing I did was pressure test the water jacket and found a soft plug below # 3 was pushed out. That scares me but it might be a blessing too if it released pressure and saved the block. I'll pressure test it again when I get new soft plug in. Borescoped all the cylinders and heads the best I could and the only thing out of the ordinary was a red film of surface rust on # 3 exhaust valve stem and seat and around the ridge inside # 3 cylinder. 135-140 compression all the way around . $190 for new exhaust manifold, Comes with new bolts , gaskets and fittings . It's worth taking a chance and putting it back together at this point and trying it again. If its toast I'll still take it fishing and order a reman long block for $ 1650 delivered to my doorstep. Those little Chinese borescopes are worth their weight in gold. [/QUOTE]
