Never use gasoline as a parts cleaner. Besides the safety factor, it's the quickest way to shorten the life of the CDR diaphram. If you're getting blue smoke that's not a fuel or IP problem, first step is to check for excessive blowby (worn or stuck rings). The 7.3/6.9 engine's blowby limit is 6" on a manometer at rated RPM (3400). Another common cause of blue smoke would be bad valve guides and/or bad valve stem seals.
