Paul,
Could you post pictures of the coolant system pressure tester that I think you and Perry were using to find
the leak in his system.  I thought the local AutoZone store had a pressure tester as part of their Loaner Tool
program but they don't.  Nether did Advance Auto, so I must fabricate one to test my recently rebuilt '87 engine.
I need to determine if I trapped an O-ring and am burning coolant or I'm still burning off the assembly oil.  I fear the
former.

One other thing, the engine "idling" is cycling up and down like a lawn mower.  I suspect a vacuum lean.  Can anyone suggest
where to look for that?

PS engine is in a car--tomorrow the sky!

Perry already had a coolant system pressure gage on the instrument panel.
Essential for any liquid cooling system.
We added a tubeless tire schrader valve to the top of the water
pump as in the first picture. Generally these are used to preflight
the cooling system with a cold leak test.

The third picture taken on OSH this year is of Chuck Dunlap's tire
valve doing double duty as a cooling system  bleed fitting mounted
at the highest point in the cooling system.

You might have to wait for Tracy to get back from OSH on the
cycling question. As I recall people have had that problem
before.
