1987 Suzuki 1.3 motor ...No miss just lots of vapor out of tail pipe , Drained all water out (only let it run a min.) runs great....My Question is could it be a cracked head . block, or head gasket,,,,,loses water really quick....

Really only one way to find out...

What I'd like to do however, is add one more possibility to the line up - the intake manifold has coolant flowing through it and on some cars, also through the base of the carb, leaking gaskets in the intake can cause similar symptoms.
