ENGINES
Some 1987 R/V, G, P and 1988 C/K models with 4.3L, 5.0L, 5.7L and 7.4L engines with throttle body injection may have a low oil pressure reading at
the gage. This condition may be caused by an incorrect oil pressure sender being installed in production. If this condition is encountered, it can be
repaired by using a new oil pressure sender, P/N 10069218. The new design sender can be identified by a "60" that is stamped on the hex drive portion
of the sender. For installation instructions, refer to the service procedure in Section 8C of the appropriate service manual. This condition was corrected in
production beginning with the following VIN breakpoints:
