n14 air comp odd issue

Hi all. We've got a 96 379 n14 1.2 m miles in framed about 100k ago. The compressor has been passing oodles of oil for awhile now. Builds air like a lizzard blowing for extra cash. The owner said we had another truck with a n14 and they chased a similar problem for months I guess they had some other problem that would cause a good compressor to blow oil through. Couldn't find anything in any search's anything you guys have ran into?

 

It builds air and holds air with no problem. Is just dumping oil. One of our other wreckers had the same problem and when they changed the compressor it still had the oil blow by problem. No one can remember what it was though. What I'm trying to find out is if there is a common problem with them that can cause oil blow by other than the compressor

 

Yea we have a few techs that are obsessed with rtv. We also have a few who use heat shrink butt connectors and don't shrink them. Anymore I tend to try to do as much work as possible on my own truck as I cannot stand other peoples quality of work.

 

the intake is fine nice and clear which I would assume would also cause slow air building which Isnt a problem. Mr.x it draws air from the intake manifold as some one decided the easy to change filter on the sidthe the compressor was to hard. #### engineers. Which causes premature falure of the compressor. I'll be convetting it to a old style filter as soon as I can get the parts
