I know there's many posts about how these eat oil. Mine goes through tons of oil. I don't have any smoke and I was never able to figure it out. I just did an ATI damper because my balancer almost fell off. I read that the front crank seal might leak in this situation. I saw some oil there but I'm kicking myself for not replacing the seal while I had the HB off. Is it possible to lose like a quart of oil for every 4 refuelings through the front seal and not see any oil droplets under the truck? I was thinking maybe it only leaks when the truck is moving and RPMs are higher?
