On the 272 engine I am rebuilding I had a tough time cleaning the oil pan because the oil had to be scraped out in chunks. I was wondering how I could clean under the baffle so I decided to take a long screwdriver and scrape out what I could. Then I put the pan in parts cleaner and took a long brushed which I use to clean the oil holes on engines and bent it so it fit under the baffle and I was able to get it cleaned
