Well I got one that’s scaring the bajeppers out of me!!!
Rear main or pan seal is leaking quite a bit of oil, bout a qt to 100 miles. So I drain the pan and pull it down, oil only, no sign of water. Flywheel covers are both off, oil only, no sign of water. I pulled the two front bolts for the rear main and the back two won’t come loose with a 1/2” breaker with a pipe extension, 1/2” impact won’t break them loose either, oil only, no sign of water. So when I got out the big guns, my 3/4” “Earthquake” impact and find I don’t have a 3/4” 6point drive socket small enough to fit the rear bolts. This was last night and it laid there all night, drippin’ oil only, no water.
While I was out shopping this morning I picked up a 3/4” to 1/2” adaptor and a 1/2” drive 3/4” socket. When I got back four hours later this afternoon I assembled everything and crawled under to see if this combo would break the bolts loose and what do find on the paper I had on the floor to catch the drip? WATER, not much just a few drops, bout enough to wet a tissue. Now I’m starting to worry, the bolts, they took two slaps from the Earthquake set bout half way up and spun loose. I’m seeing a few drops of water now seeping from the front of the bearing cap. I haven’t pulled the rear bolts out or the cap loose yet till I figure out what’s going on. I it possible for one of the bolt holes to go up into the water jacket back here???? First thought was freeze plug or cracked block at #6 but put that those out of my mind because this wasn’t leaking before I loosened the rear cap bolts.
Also I see the corner edge of a piece of shim stock sticking out from between the cap and the block. I know the rods were shimmed but I didn’t know the mains were shimmed, are they????
I really counting on some experience voices here guys, anyone ever run into something like this before?
