SERVICE MANUAL UPDATE
The 1987-90 2.8L and 3.1L, (VIN Codes T, V, and W) engines have intake and exhaust pushrods with different lengths. To distinguish the different
length pushrods, they have been identified with paint. The paint markings may be hard to recognize after prolonged use, but the pushrods may be
identified by their different lengths. The intake pushrods are marked with orange paint and are 6 inches long, the exhaust pushrods are marked with blue
paint and are 6-3/8 inches long.
