Hi All - this weekend I'm going to be adjusting my valves in my continued attempt to pass smog and was checking the FSM I downloaded from online and there's a difference in gap recommendations between the FSM and the Owner's Manual that the truck came with.
I downloaded the FSM from another forum, it has a blue/white cover and has, "TOYOTA 3F-E ENGINE REPAIR MANUAL SUPPLEMENT AUG. 1988" and then down at the bottom Pub. No. RM134E. On page EM-9 the states the gap should be 0.8 mm or 0.031 in.
The owner's manual states 1.1 mm or 0.043 in.
So my question is, is the FSM specific for each year? The sticker under my hood states I have a 3F-E CAL engine in my 91; is the 3F-E in a 88 different from the 3F-E in a 91 and would they have different gap requirements?
