Tech Procedures:

1. Computer Rotation:

It is recommended that each track and/or series should purchase from Schwanke Engines one computer to be used for random rotation among competitors. The atmosphere of a competitor knowing he or she may not always take the same computer home they came with is the most important tech procedure. This will help eliminate any need for internal inspection.

2. Seal Inspection;

There are four seals on the engine:

One on each center of the valve cover

One on the timing cover right side below water pump

One on the right front corner of the intake manifold

The seal numbers are sequential. Five seals are produced for each engine one is held back for teching and/or field service available by paper trail, tech and the race director signatures. You then need to call Schwanke Engines for the seal. (Example number 60001 = 6 represents 6000 truck engine and 001 is serial number).

3. Scanner Test:

The system also features a 16 pin OBD II ALDL connector a Tech II or Snap on Tools scanner can be used to access data stream. Call Schwanke Engines for VIN information.
