none of the bolts are in water
on the end its a blind hole the others are in the oil,and oil can wick up the threds and pool in the intake by the bolts
sounds like it may be an intake gasket not sealing at the water port
did you use any sealer on those water ports?
the back is blocked by the intake but still you should use some sealer on the back water ports also
check the water pump bolts that go thru the t-chain cover as well
make sure your not getting any water in the oil pan while your checking
best bet might be to pull the intake and redo the gaskets with sealer on the water ports
have not talked to you in a while,hows it been going?
