Excessive oil passing into air tanks and purging out air dyer, HELP!

Just run a good size filter filter on the hose than. I stole mine from a parts motorcycle that was around. Old trucks had filters on the compressors picking up outside air so its nothing new. Try it and see. If the compressor needs the air under pressure from the engine it'll let you know by not building air pressure normally. Just try it in your driveway before you take off on some trip. If it seems to work normally try it out and see if your oil issue gets any better.

 

Yes, you can run a small filter on that black hose. Where it is disconnected from the engine, you will have to block that fitting at the engine. The oil drain is inside the bottom of the compressor housing where it bolts to the back of the front cover and oil just flows by gravity into the back of the front cover. You would have to remove the air compressor to inspect this.

 

Under high boost I think that grey cap will blow off at the intake manifold. The air filter for the compressor looks ok.

 

Honestly, sometimes stock or factory is the way to go..

I would of just got some bigger fittings on both ends and went up to a #10 or #12 hose.

Then your not screwing around with filters and stuff

 

If there is a screen under that filter element you made up it should be ok. That cap could be iffy. That fitting in the manifold should be pipe thread too l think. If you take that 45 degree fitting right out you should be able to get a plug at any parts/plumbing place. I eould definitely take it for a half hour or so drive first to try it out before going on a 3000 mile trip!

 

I would start with a new air compressor.

Any way you look at it, yours is passing oil. New or not. It's no good.

Start with that and go from there.
Change your air dryer cartridge same time
