how to time a 1996 4.0 engine jeep and number one cyl.
The one towards the front of the engine.
There is no 3.1 engine in any Jeep
Each year, engine, and transmission combination will have a different part number.
Right above the motor mounts on the 304 V8 engines there is a large casting mark that says 304.
That is a little casting identification number in the cluster lense. It is not a malfunction indicator, just ignore it.
JEEP xD
