Water in oil after doing timing chain .. stumped

several of the bolts in the front of the motor go into water...as you disassemble the engine...water could have ran down into the pan undetected......then you fire it up ..presto water in the oil...

have not used a gasket on the front timing chain in 25 yrs...only use the blue rtv...if you have any corrosion from years of the use the rtv will fill the small gaps and seal
