Left the van pressurized at 15 psi last night and both heads leak.  Also a
bunch of coolant came out from up front I need to sort out. I'm guessing
plastic pipe failed or the heater valve.  I guess It's best to find this out
now rather than on the road.  Something to do this winter!

BTW, my Motive pressure brake bleeder works great for pressurizing the
cooling system through the pressure cap.
