I am happy (but embarrassed) to say...I found tiny weep on my regulator gauge going to the heater core. It was a drip every few seconds and it was being blown back along the head gasket line by the fan and probably seeping in under the edge of the gasket and then boiling off due to the block heat.
I replaced the valve with the regular nipple and low and behold the bubbling slowed and stopped over the course of a few minute ride.
The engine runs great but does not seem to have much power. I probably need to readjust the valves.
Do new rebuilds typically gain power as they wear in? I would imagine the rings need to seat and such or should I be looking elsewhere for a power sucking issue.
Relieved but blushing
