The iboats forum moderators are excited to announce that at this time it appears the iboats forums posting pictures function is working once again. Though we cannot promise for how long, we're hoping for indefinitely.
I have a 4.3 lx/v6 that filled the cylinders with enough water to lock it up. I had the exhaust manifolds pressure tested and found no problems. Is it possiable for an intake manifold to cause this type of problem? engine ser# is of146501.
if it's not the manifolds, then you probably either have a cracked block or a blown head gasket. Do a search for "Water in Cylinders", and you'll get some good advice. Did you get all the water out and oil the cylinders?
