There is a hole that developed in the block of my 93 Explorer (4.0 non-sohc) a couple weeks ago. It shot out coolant when my truck heated up. I was only a few turns from my house, so I'm hopeful that nothing else was damaged. But until I get into replacing my heads, again, I wanted to know what everyone would suggest I do. The hole is in some plug that seems to have been hammered into my block whre the water jets are. It is on the outside of the center cylinder on the pasenger side. This is right inside the passenger side wheel well. The pics show better the location. The pics are before and after I tried cleaning up the hole. I thought about patching it. When I cleaned up the opening with a dremel and a soft wire brush, the hole enlarged. The metal seems to be very thin near the hole.
Waht are these plugs and are they replaceable or should I patch it with JB Weld and hope the motor lasts a few more months?
Regards,
