I'm trying to break in the new cam and last item was to add water and check for leaks. W/P housing was first, got it, but now I have a leak BELOW the dipstick hole. It isn't running down the rail and falling off there, and it isn't a leaky head gasket since the sides of the block are dry. I even pulled the tube out and checked to see if the case was full of water, but no dice, just oil well below the rail level.
How does one get a drip every 2 seconds from somewhere with no water jacket?

Yeah, BB.
You know the angled boss where the hole for the dip stick is machined? between the bottom of that (pan rail) and the oil pan gasket. Dead center of the boss.

Yes a pic is worth a thousand words. I'd drain the oil in a clear jar & see if there's water in the bottom of the jar by looking at the underside of the jar as if it's a slow leak there might not be very much water at this point in time and if the minute leak is on the outside water jacket there at the bottom which it sure sounds like, might pump it up to 15 lbs with the radiator pressure tester & see if it'll make it leak faster & be easier to spot EDIT may need to drop the pan

put a piece of plumbers putty (chewing gum) on each side of that boss right in the pan rail and see if it drips uphill from that boss. Maybe thats just the lowest point from a running leak? Blow some flower onto it and see where it sticks. Thats where its wet or oily. Brown paper towels show water well to, start blotting.

I'd love to diagnose further, but as oddly as it leaked, it inexplicably quit too. I went ahead and broke in the engine with it as was (dripping) and by the time it was over it had stopped.
Whatever.

There is no water within 5-6in of that location . So its either running down from a frost plug or you have a cracked block, or leaking cylinder head gasket or from a stud that holds on your manifolds/headers.
See if you can press apiece of cloth somewhere above the area indicated and see if it stops leaking .
You could also get some paste that detects water and just put a line of it above the boss horizontal to the pan rail . service stations have it to detect water buildup in the gasoline storage tanks or you may be able to buy some at a good industrial store.
Just on a curious note , is your engine sleeved ? If its not sleeved and you cannot find a external source of the water , you must have an internal block crack. I personally don't see any other options that would make the block leak there .

...yes, it is sleeved in the #3 hole. Why do you ask?

OH OH !!!!Thats why I asked . guess where # 3 is at . Not a good sign . If it continues, and you cannot find an external leak , I thinking that the seal on the bottom of the sleeve is leaking or not installed at all . hate to be the bearer of bad news but you may need a tear down to seal thing up .

If the seal is the problem there would definitely be water IN the case, right? None present.

You would think so , but maybe where it is not leaking a lot and just a few drops it is possible that the new engine with higher heat is vaporizing the few drops. are you using synthetic oil ? Why was #3 sleeved ? i,m guessing it windowed the block when it threw a rod and also took out some of the cylinder wall. I always thought that there were some casting #s , build date and what shift built the engine between the engine mount ear and the boss to the rear of it(just below #3 sparkplug). were the numbers ground off because of a block repair?

He had a crack in the cylinder , no windowing from throwing a rod . As far as a seal on the sleeve , this isn't an alum. block , there may have been some sort of sealer put on the sleeve but for the most part the sleeve is a press/shrink fit , it's cooled to shrink it before being installed.
He either has a leaking freeze plug or a porous spot on the block , but that would show up on the paint , especially if that is MP engine paint .
But he did say it stopped , if it were me I would throw a bottle of Moroso ceramic seal in that block just to make sure the sleeve is sealed ...

I'd still pump it up (cold and hot), wouldn't have to tear into it & renting the rad pump tool is cheap. If you need to do something about this now is the time to find out

and added about 1/2 a can of stop leak. No more drip.
