Rework Procedure
1. Check to see if the head is supplied by CBS or Gosselies. The part number is located on the front of the head on the governor side beside the lifting eye, just above the front cover. In Marine applications, it is best viewed using a light to look between the expansion tank and heat exchanger.If it is a dot-matrix, then the head is from Gosselies. If the part number is stamped, then it is from CBS.
If the head is from Gosselies (dot-matrix part number), then the engine is good and no further work is needed.
If the head is from CBS (Stamped part number) then further inspection/rework is required.
2. If the head is from CBS, remove the valve cover.3. Using a sliding caliper, align the caliper vertically using the edge of the injector spring, measure and record the distance from the timing ledge on the injector to the top face of the head for each cylinder. This measurement will be in the range of 8.39 mm but can vary from engine to engine.4. If the variation from cylinder to cylinder on the same engine is less than 0.40 mm, then the engine is good. Re-install the valve cover. No further inspection is necessary.5. If the variation from cylinder to cylinder on the same engine is greater than 0.40 mm, recheck to verify measurements, if the difference is still greater than 0.40 mm, proceed to Step 6.6. Remove all (6) injectors. Using a depth gage with flat end and a 0.75 inch diameter steel ball dropped into the sleeve, check and record the distance from the top face of the head to the top of the steel ball. This measurement should be 2.583 0.18 inches (65.61 0.46 mm).7. Remove the injector sleeve on any cylinder
