I am about to install a distributor in my 93 MX6 w/2.5 liter v6, but I have read different accounts of install ,about setting timing to tdc before pulling distributor, but since it will only fit 1 way, what is the point? I am going to mark the head where the mounting ears of the distributor are so as to set the new 1 exactly where old 1 was, I am asking as I have never done it before, I have painted plenty, but never worked on a motor before. on a MX6, so I would appreciate some help to let me know if I am missing something. I will appreciate it very much, already have new PCM installed inside under radio, hoping new distributor will get it running again. Thanks again. Dave H.
