    Re: PS

    For what it's worth, my "donor" was a brake stud (all I could find in the drawers in Pep Boys with the correct thread). We cut it down, slotted the top and tried different lenghts until it stopped going in with the "head" just below the block surface. The finished piece is 1/4, maybe 3/8 long, and with all the effort we can put on it with a screwdriver, it tightens down and sits just a bit below the surface.

    From examining the hole, the threads go down further than this home-made plug is long, so obviously something is not straight or the plug would keep screwing in. I can see that at some point the threads stop, then start again. Very weird. I am kicking myself for not noticing before I started putting the engine back together, but as I say, I never noticed the hole until I saw the head partly covering it.

    I am overthinking this, but as I see it I either pull the head again, clean the hole and my plug (it's in there with thread sealer now) and install with epoxy, or I try to tap the hole for the next size pipe thread. I really don't want to make the hole any bigger. A machine to remove the threads is beyond my garage - that would require a full tear down and a visit to the machine shop.

      that hole intersects a vertical hole which you attach you oil pressure fitting at the rear of the block behind the intake manifold. i would check to see if there was any of that hole that was not threaded before it intersects the vertical hole and install a cup type expansion plug. then i would install the "bolt" with epoxy as a backup. also i would check to make sure the shop did not remove the cup type expansion plug from the vertical hole right above the rear main bearing cap. you can check this by inserting a small dia rod into the hole where the oil pressure gauge fitting goes. the rod should go down about 8 1/4" and stop if the plug is still there. if you do not have the rear main cap on the block the rod will fall all the way thru if the plug is missing. you can call me at 724-468-5692 if you care to any time after 8:00 eastern time

        Image for all to see?

        I'm not very computer literate, but I've tried to post the image to a web page for my pictures. I'm hoping the site below will work so that anyone following this thread can see the plug in question. My appolagies in advance if this doesn't work. I hate having to email jpegs directly to to an individual when others may also be interested.
