Water pump leaking through bolts

Think some of y'all have seen my 641 that I am working on restoring. Was gone for the last three days, and came back this afternoon to stroll down to the garage to find a tiny bit of coolant leaking out the front. Coming from the bottom water pump bolt.

When I first started the engine the other week, I had all three water pump bolts leaking. So I drained the coolant and put teflon sealer on the bolts, filled up, and was good.....until now. Bolt holes were chased out good before hand, and the three bolts are all new, also.

Question: Is it common for these things to be hard to seal up? I wouldn't think so, but I suppose I'll pull the radiator and water pump back off and make sure it's not a gasket messed up and letting it come out around the bolt holes. But maybe there's something obvious I'm missing here.

If there's one thing I can't stand, it's a leak. Especially over that new paint!!!

Thanks,
Kevin
 
is it leaking due to failed gasket, failed seal, or through bolts from the threaded portion.

I agree with Bern on the permatex for two of the solutions.. but if seal, a pump replacement is in order. If gasket, a new gasket and permatex.. if threaded holes are leaking, permatex again, but bolts could be hard to pull next time around.

I get the permatex by the large container with a brush in the lid.
 
Pulled it and appears to be coming through the threads of the lower bolt. Had previously used the white teflon Permatex #14.

Cleaned everything real good, new gaskets, and used Permatex #2 this time. We'll see. No excuses for it to leak this time around. I usually have good success with the white Permatex, but clearly it wasn't working. We'll see.

Thanks!
