wilbur Posted September 4, 2019 Author Share Posted September 4, 2019 Yes replaced bolts that were a year old. Money wasted i think Quote Link to comment https://www.bigmacktrucks.com/topic/58719-making-oil/page/2/#findComment-431459 Share on other sites More sharing options...
wilbur Posted September 7, 2019 Author Share Posted September 7, 2019 Well after 750 miles it didnt gain any oil. But I think i put the Delta seals in backwards. I put the skinny side of the triangular o ring to the outside. and the wide part of the nylon to the outside.

Mack Technician Posted September 7, 2019 Share Posted September 7, 2019 You can’t install them any way but correct. If you try to roll the formed triangle ring flats-out you’d need 4 hands to pull it off.

wilbur Posted September 8, 2019 Author Share Posted September 8, 2019 Your right. now that i remember the plastic rings are made with the skinny side on the I.D. They will only fit the o ring one way. The skinny part of the triangle has to be on the o.d. Thank you.

wilbur Posted September 8, 2019 Author Share Posted September 8, 2019 Little hard to be sure with only 750 miles, but so far it didnt make any oil. Still dont know what fixed it.? delta orings or eups.

wilbur Posted September 13, 2019 Author Share Posted September 13, 2019 So now have 1800 miles on it and it is actually using oil now. I think the heat is evaporating the diesel that was in the oil now that the leak is fixed. Its actually down 1/8" in the 1800 miles. But since the new EUPs i lost 0.5 miles per gallon.

Mack Technician Posted September 14, 2019 Share Posted September 14, 2019 Your oil replacement system has been eliminated. Now your going to have to add a gallon between changes.

terry Posted September 14, 2019 Share Posted September 14, 2019 Most people would be tickled to use only 1/8 inch of oil on a truck dipstick in 1800 miles. terry 1 Quote Link to comment https://www.bigmacktrucks.com/topic/58719-making-oil/page/2/#findComment-432052 Share on other sites More sharing options...
wilbur Posted September 14, 2019 Author Share Posted September 14, 2019 What about the fuel mileage.? Should it lose with new EUPs.? I was getting 5 now 4.5 mpg.

Mack Technician Posted September 15, 2019 Share Posted September 15, 2019 Maybe increased driver confidence causing foot swelling? You are hyper analytical. Not a bad trait.
