for what its worth..mine has had a low oil pressure since I bought it in 95. since then it has taken me to key west and back and is still chugging...I seem to recall there is a nut on the carb side that can be adjusted to increase/decrease oil pressure..Watch them additives,I tried one and while my engine sounded alot better,my trannie was not real happy with it.
