    Hey, will this work on the standard DMC (B28f) 2.8 PRV too?

    Thanks

    Speaking of which: even though we have single piece crank pulleys, DeLorean owners should still exercise caution timing their engines. Do not blindly assume that the scale is correct (can I hear an "Amen" Louis?).

    AMEN Bill ! Now that my timing is right, well, much better than it was originally, I don't even think the mark is on the scale at all! My timing was adjusted by ear by a Delorean Mid-Atlantic member who's name escapes me, as many things do. He was very, very nice though, unlike some other members I've met. It was at a spring social, fall foliage tour, or a summer fun run, I don't even remember what time of year it was now. Man, I'm burnt! I guess "toast" is a good name for me after all. All the bong resin in my brain has coated my nerves. But that's all behind me now. I swore it all off.
    Bill might remember his name, Bill's memory is like a republican elephant. All that Diet CheerWine must clean out the neurons or something.

    5/16 drill bit (regular length) before dropping into index hole:

    5/16 drill bit (regular length) in the index hole:

    Same procedure using a 7mm allen wrench with the water pump in place (drill bit won't clear the heater core return -- note hose clamp also removed for clearance):
