overheating at idle 120-130

posted by  someone claiming to be Joaquin Novara on  Wed Jan 28 06:51 CST 2004 [RELATED]

A year ago I was a similar problem with my 121. Check for air leaks between carb and header (or trought the carb butterfly hubs). Also check the equivalent of the B18 PCV valve on your B20 (¿flametrap?, ¿bypass valve?,¿who knows?). A stuck open PCV are equivalent to a air leak at idle (and due it, at idle the engine dies). A trick: Use a childs stetoscope (from a medical kit toy -yes, the plastic one), or use a plastic tube with a stryfoam coffe cup (unused) attached in a side with tape (hand made stetoscopy old toy on my child days) and detect the leak by ear.

On the other side, overheating can be related to a stuck thermosthat (at last, it was on my car).

Happy debbuging...
