hello. i had a question about the water pumping through this motor. after the thermostats, the tubes carrying water from the heads t into 1 tube then it then goes to another t just before the "peehole". that t sends a tube back to the engine just below the upper powerhead gasket. where does this water go? i took that tube of and a little water spat out of it but lotsa water through the telltale tube. does that push out from somewhere or pump water back in somewhere? Thank you guys!
