Information: Sub-Zero Breather Kit
Models: All 164 Models
Date: 3/08/95
It has been determined that the oil/vapor separator may freeze on 164 models that experience extreme SUB-ZERO temperatures for a extended period of time. This condition will cause the crankcase to pressurize, resulting in hard starting or oil blowing out of the sump.
For vehicles subjected to extended SUB-ZERO temperatures, a "Sub-Zero Breather Kit" is available. The kit consists of a spacer plate that mounts between throttle body and air intake plenum. It is ported and fitted with a Positive Crankcase Valve (P.C.V.) that tee's into the breather hose going from the oil separator to the large black rubber intake hose, upstream of the throttle body.
Note:All pieces must be ordered individually to make up a complete kit.

Installation is as follows:
Install P.C.V. (#1) into plate (#2). fig.1
Using 2 Gaskets (#3) bolt the Plate (#2) between throttle body
and the air intake
plenum. Substitute original throttle body bolts with - 2 M7xlx5O
(#5) & 2 M7xlx6O
(#4). fig.1
Cut the black rubber hose coming from the oil separator to the
large black intake hose approximately 245mm (9.5 inches) measuring from the oil
separator. From that point measure 3Omm (1 inch) more and cut again leaving a 3Omm gap in
the hose. fig.2
Install plastic tee (#6) and hose (#7) to P.C.V. & plastic tee.
Use hose clamps (#8) on all 4 connections. fig.3
