[KULTULZ]

Very possible. Did you see the coolant on the cap immediately after dropping the pan or was it a while later?

Do what you need to do to make the cooling system intact so that it can be pressure tested before reassembly. You don't want to put it back together and get an unpleasant surprise.

It may also be a rear core plug on the cyl head(s) or a leaking intake manifold gasket.

Was the coolant protection down far enough to prevent a freeze?
