Don, Since I now own a 200 hp Optimax, I try to keep abreast of all possible failures and ways to prevent the failures from happening. I just re-read your thread "Optimax Compressor Failures vs. Oil Used vs. Cooling Issues: http://www.bbcboards.net...-used". I didn't see any mention of removal of the cooling water strainer to the compressor and checking for restrictions or blockage. On another site a guy posted that he had had 2 compressor failures and since he has started removing and cleaning the strainer he hasn't had any failures. My question is do you think this should be performed during normal maintenance?
