Hi all. I have a 454 rebuilt professionally 90 run hours ago (3 years) that is freshwater cooled. At 2800 RPM, temps stay cool, but I am puking foamy water from the cap.
Does anyone know of a common location in the manifolds or elsewhere that might explain this??? Or possibly a stuck thermostat causing the water pump to cavitate??
I might have to rig up a leak down tester off a scuba bottle to check the cylinders.
Thanks for any help or thoughts.
