Hey Evan,
How are you? We met at the Dream Cruise about 2 years ago. Sorry to hear
about your trouble. I do have one question to for you. I wondered if you
had seen on either the coolant flushing or maybe an oil change traces of
oil or coolant in the other liquid?
I would think that if the head was cracked that usually an exchange of
fluids would occur.
Just wondering. Also there are 2 air bleeders in our 85's coolant system
one at the radiator and one at the back on that metal coolant pipe that
runs across the engine. When you bleed the system are you including the
auxiliary heater in back or do you have that valve close?
I know I have more questions than answers for you, but maybe some of these
are key.
Report back and good luck.....the weather is starting to suck in the
mitten!!
Tony
