    I have a oil leak on right side of my n14. I originally thought it was from around the filler tube but after installing a new gasket still a leak. It drips all along the right side of the pan front to back but after cleaning up along the pan no obvious signs of a leaking pan gasket. It leaks while runnings but really starts pouring out after shut off. After a hard run when i shut it off theres a giant puddle under the truck. Any ideas im stumped

    Sounds like the accessory drive seal.

    I had n14 had to replace turbo line twice.It would leave a puddle when I stop.the design of the engine makes the turbo line rub on the inside.I have a detroit 60 series now and My n14 was alot better

    Hard to say with out seeing. It could be a piston cooler/Oiler as well. The only thing you can do is clean it good and run it and watch. Have you seen a decrease in oil pressure?

    piston coolers is my thought to,after replacing 1 at a time last time i was in said replace all of them,fairly inexpensive part,if 1 is doing it the others will break soon,have them all replaced
