On my 2003 U320 there's 3 drain valves just in front of the drivers side front tire on the frame and one drain valve in front of the drive tires on the drivers side also.

Ok I know most of you have been sitting on the edge of your seats waiting for an update  ;)

As I learned today there are 4 remote dump valves on this coach.  Started with the wet tank.  blew out a good amount of the dreaded white powder, NO oil, NO water.  Went to the front.  there are three valves behind the driver wheel.  First valve closest to the road dripped 3 or 4 drops of water, NO oil, NO powder.  Next valve blew out a small amount of powder, NO oil, NO water.  Valve closest to the curb - same as the previous.

So with my limited experience I believe, tell if I'm full of sh*t, is that the compressor is outputting too much oil and has clogged the desiccant cartridge.  I am hoping this is not the case but BEFORE I put the reman Haldex unit on I need to know if this is the cause of the problem. 

Is it possible that the DA34100 is really NOT compatible (isolation valve or lack thereof) with my 20 year old Wabco 4059825 ?  Or do I need to look into a new compressor ?

Ok I'm all ears.

Good Morning,

 

The Haldex was installed within the last 3 years and I noticed it appears to be leaking some oil around the base of the cartridge housing.  It's not dripping and appears the oil is made its way down to the lower half of the unit.
  Is this likely a maintenance fix ?  New cartridge and O-ring ?

The dessicant cartridge is an annual thing, given most RV use every two years.  So yes: New cartridge and o-ring.

IF your compressor was passing oil,  several quick cycles would show oil on the floor from the purging of the coalescing filter.
