Should have known better (do now) but went into local FORD stealership and asked service writer if they had any techs that could time an "IDI 7.3". "I have plenty of techs that can time that". How much? Starts typing and asks year. I tell him "93 7.3". He says, "that's a diesel, I don't think you can set timing on a diesel!! Not just my diesel, any diesel. I said of "course you can" so he wants to start diagnosis at $125/hour. I said "don't need fishing expedition, just set timing." At that point conversation went down hill and I left laughing and grumbling (but went around back to parts for some VC9). Will not darken service dept doorway again.
