Air Dryer

[ac7880]

Leroy and Tom.

The BMC uses a Haldex (Midland) Pur Air Plus air dryer. It is mounted
on the passenger side low at the rear. Several BMC owners have had
blowby spitting oil that hits the tow car after several hundred
miles. One member has changed to a "Econ" version of the Haldex
Midland (model DA33200) based on a Cummins engineers advice, and this
has solved the problem.

details the change etc.

I'll read the pdf provided below, but since I rebuilt my Pur Air Plus
air dryer recently with NAPA Part number DQ6026 ($123.99), consisting
of the desiccant canister, coalescing filter, 175 PSI
pressure relief valve, orings, purge valve shield, screws etc, I
think the "spit" is just the nature of the beast.
