Dd15 testimonial

[4vmach1]

When you see oil coming out of the crankcase breather assembly tube on a DD13/DD15/DD16 it should be replaced and you will not see any oil or smoke coming out the breather tube. These were done a lot under warranty. There shouldn't be any smoke coming out the stacks with all your emissions filters in place.... your engine has a problem i would get it checked out on a basic ISB test to make sure your injectors aren't overfueling and does it smoke when its on a regen under load or when you're driving every where?
