Navistar engines equipped with
HEUI injectors have undergone a design change that results in changes to the
injector compression gasket. During the model year 2000, beginning with
number 1194039 the injector sleeve material in the head was changed to stainless
steel, as shown in the photo on the left. With
the change in the injector sleeve, comes a change in compression gasket
material. The typical "copper" gasket has been changed to a "stainless
steel" gasket. It is easy to distinguish between the 2 gasket materials.
This change applies to injectors with BI, BJ, BP and BN body codes.
Application information can be found
All BP and BN injectors provided by us will include the new stainless steel
gasket, since these injectors were never produced to use a copper gasket.
All BI and BJ injectors will be shipped with both the copper and the stainless steel
gasket, neither of which will be installed on the injector. It is up to
the installer to install the proper gasket before installing the injector in the
engine. Use a 8mm hollow drift punch to carefully tap the gasket over the
nozzle tip until it bottoms on the nozzle retaining nut.
Note: It may be possible that rebuilt heads used with other injectors are
also affected. For this reason it is a good idea to determine if the head
in question has stainless steel injector sleeves. If it does, use the new
stainless steel gasket. It is also available as a separate item part
number 1830317C1 in our online catalog.

Custom designed add on filter kits for both Dodge and Duramax applications. The factory filters on these
applications are lacking at best, and this is both the best and
easiest way to avoid costly injection system repairs.
