That hole goes nowhere. What intake gaskets are you using?

it doesn't always do it, sometimes randomly
Could be your intake gasket is seeping around that front coolant port, and existing out that open manifold hole.
Can try retightening the intake manifold bolts to help seal it up.

See post #5. Use those gaskets if you need to switch gaskets. I agree to retorque the intake bolts and it should go away. If the heads of your bolts take a 1/2 inch wrench, you can only tighten them to 210 inch pounds. They look like 3/8 in bolts with a 9/16 wrench head and should be tightened to 30 foot pounds. Just check to be sure.

More often than not, that tin stat house leaks, (which is why I stopped using those, years ago), and it dumps fluid onto the top of the timing cover. I suppose those holes could catch and hold that leakage.
Plus I installed studs there so I could tighten the chitout of them without wearing out the threads. Good luck.

This ^^^^ is what I would look for.
if you replace the 'stat housing you can get new cast iron ones from NAPA - more leak resistant than the aluminum ones (IMHO).

The worst ones to leak are the chrome ones with the O ring for a seal.
