Yes I learned that with my 425 olds in my other boat, I was thinking that the oiling problem has been around since the olds motor was made, Do you think a builder like hondo or hardin would still install the motor anyway? The guy I bought it from said he had never even heard about it and it was stock, he had bought it from his brother ( who had bought it brand new)and nothing has been done to it. I am not going to rebuild it because it runs to good, I was just thinking after all the problems people have with oil pres.,Their motors Must not be made for marine use. Ill post some pics. today, I paid 750.00 as a second owner and it is in very good cond. I was just going to clean it up and paint it or try to wet sand and fresh clear coat try to make a buck.
