Timing marks for ford f150 4.9 6cyl 1992?
I have a 1992 f150 4.9 6cyl.Gas mileage was getting worse.Thought it was the timing.Hooked up the timing light and looked at the penger side sawtooth marker with the round peeper and hole in it at 10deg TDC.Unplugged the spout/Could not find the spout at first/ .There are TWO sets of timing marks,one on the drivers side of the harmonic balancer and the other penger side sawtooth.I have experience doing auto repairs so this was no big undertaking,UNTIL, I hooked up the timing light to the No1 cyl wire and loosened up the Distributor tighten down nut.rotating the distributor and looking at the penger side timing marks -the harmonic balancer has a notch machined into it and im thinking that is the timing mark- I could not even see the timing mark on the harmonic balancer/which i marked with chalk/ and on the drivers side marks/engine timing marks/I could not see the 10deg BTDC either.SOOO Can someone with FORD experience HELP ME please.Gas is $ 3.85 per gal and i want this truck timed correctly as to get the most out of my gas mileage.Dig when i hook up the timing light to the 3rd plug wire the marks come into focus clearly ???? Have hooked up the timing light to the no1 spark plug wire and can not see the timing maeks on the harmonic balancer ??? what gives ?? Any FORD gurus out there..Thanks a bunch from Hampton,Virginia
