I attended the Wilmington Copeland class and the seminar was excellent. We all enjoyed it and appreciated your time and wisdom. I wanted to ask a couple of questions I didn't get in at the session. First, does the test for determining blow by on a refrigerant cooled compressor apply to an air cooled compressor as well, and if not,what means would be used in the case of an air cooled compressor? Also, do you know of any target temps for crankcases? Basically, what is considered too high of a temp on copeland crankcases? Thank you again for an excellent seminar.
