As I have been getting to know my new to me boat I noticed the lack of sludge and crud under the oil fill caps on my 2 Perkins 4.236 engines. I have had diesels before and I currently have 2 oil cars and I know that they can get dirty. These are vintage 1975s with a reported 3500 hours on them. I have put about 35 more hours on them since changing the oil this spring and it still looks amber. Do these really run that clean? Do you think someone had the covers off and cleaned up in there?
