Detroit Diesel Series 60 14L Factory Reman Break-In “Wet Stacking”

Its pretty normal for the first few thousand miles. It should quit. Limit idle.

 

It’s normal alright. Might even see some oil out of the stacks sometimes. Usually around the turbo, and exhaust components. Fuel mileage may not increase till rings are properly seated. Might take 70k miles. I just had mine done, it didn’t do it, but last one did, pretty bad for the first 3-4000 miles. I’ve got 29k on mine now. Fuel mileage is terrible. Should jump up 1 mpg around 70k, then run an overhead. It’s been running too cool in this weather also. I thought a thermostat was stuck open. Just my new radiator doing it’s job. Going to block my radiator off. Needs heat to seal rings.

 

Change the oil soon. I’ve always heard 5000 miles, I did mine at 6000. Then again at 10. Wish I would have done it much sooner, judging by all the metal shavings found on drain plug. I’ve also let it idle a lot more than I’d like. Already getting some blowby. Hoping I can still get it broke in good. Mines a 12.7, but same principles apply.
