Block water leak

Sorry. the heads are iron.

The "nail " is a couple of inches below the head/block seam. That seam is dry with no leak stains. I'm wondering is this is a cut of welding rod welded in place. My camera is sick at the moment.
 
sounds like one of the casting wires coming through a corroded spot in the block.
don't torque manifolds to 55 ft lb,the 7/16 bolts may survive but 3/8 bolts will brake or strip the threads. John
 
I wouldn't disturbe it until you are ready to fix it. I don't think it is a welding rod. I can't imagine any welder leaving a rod sticking up out of a weld. Maybe someone shot at you with a nail gun?? There were some nail like studs that were made to weld on sheet metal to pull dents. G.M.
 
thanks. It looks funny sticking out behind the exhaust manifold. Clearly a homey fix of some sort. I'd like to be able to see if it ia fix for a crack or a hole plug. I know about stop-drilling. So far I'm for leaving it alone.
 
I checked again and barely touched the protrusion. It was a stalagtite and crumbled. I'm guessing the rust built up as the leak weaped. I'm still going to leave it alone, but watch it. It is behind the exhaust manifold and hard to reach.

Clem do you have anti freeze or rust preventatives in the coolant or are you one of these plain water guys?? I would think if there were preventatives in the water you would have a seep but the larger formation of rust puzzles me. This will get softer and larger over time. It may be an easy fix now but more difficult in time. Some times these dreaded repairs arn't as bad after you have tiume to think about them and have a plan. G.M.
 
Water leaks tend to errode the hole faster and faster as the pin hole gets bigger. I'd recommend scheduling a fix for it sooner than later. Holes like that can get a lot bigger than a guy would want it too and faster than a guy might think it could. Lock & stitch might be the best fix for cast iron since the metals are the same. It's hard to say how big a pocket might be on the inside of that leak in the water jacket wall.
