If the second shop never looked at it then how are they going to diagnose it over the phone?The second shop I called said they believed if the shop its at now couldnt do it they didnt think they would, so wouldnt even try.
Im hesitant to try to fix it myself, I can wrench but just not good with drilling and retapping, usually end up off center.
Has anyone tried using the triple oversize inserts for fords? I havent gotten exact measurement but the hole is bigger than a 5/8" tap. I dont want to give up on fixing it yet but the body is rusting badly so its not worth fixing if the head needs to be pulled.
Highly doubt that will work since ford spark plugs are drastically different than what we use. ford 5.4 spark plug - Google Search
