wilbur Posted August 21, 2019 Share Posted August 21, 2019 2000 460 It was rebuilt a year ago. Since the overhaul I been making oil. In 10,000 miles its up 3/8" above the mark. Before the overhaul it was fine ,I used to add between changes. This has to be from the EUP o rings.? correct.? Is there any other place you can think of for fuel to get in the oil.? I was thinking the plunger in the EUP pump but it didnt do it before. Just since the EUPs were out and put back in. Here is the latest oil sample report, not good. Thanks for your help. Where should I start. 80-190803 (2).pdf Quote Link to comment Share on other sites More sharing options...
