I am tracing the source of coolant in my oil. I believed it to be a head gasket. The intake manifold gasket was blown between the water jackets and oil gallery, but went on to replace the head gasket anyway.
Removing the bolts from the cylinder head, water was gushing from some of the bolt holes. (System was drained). Being the first time I removed a head, is this a common occurrence?

Hi Johnny,

Yes, if you didn't drain the cooling system. Even if you did the coolant shouldn't gush out but will kinda pour out like if you hold a water hose up without the nozzle and turn the water on very low.
