    Well I'm not so sure I would encourage you to buy measuring equipment that you may only use a few times...........but that's up to you.........on the flip side I think that motor does need some attention, and some precision measuring to gauge just how much attention it really needs..........

    I always find a use for tools, plus I haven't found a machinist who will do any work with the block in jeep. There are a few more that I will call this week. Not many will even touch my f-head. I'm trying to learn more. I figure I can measure out the guides and see where I'm at if there good I'll measure my valve seats if they measure good I'll lap new valves and run it. If guides are out I'll change them. I'm still reading about reaming and cutting valve seats that might be more then I can do with tooling. Though I was looking at the hand cutting with valve seat cutting seems doable as long as I take my time.

    What's your location, roughly. Good guy here in Chico, others have good machinists in their neck of the woods.

    If you found such a shop, they would take the whole Jeep and charge you to R&R the engine.

    Typically you bring the stripped parts to the machinist. That's the definition of a machine shop, vs a garage. Finding a shop that will machine the block in the Jeep is an unreasonable expectation, IMO.

    I've taken engines to machinists before, I was hoping to find a machine shop with old school tools to do fix my valves in block without taking it apart. I'm going to be moving soon that's all. Rather just get fixed what needs fixing with out rebuilding the whole engine if it doesn't need it. I found a machine shop who will fix the valve seats with out pulling motor apart, it does need to be out of the jeep.

    Engine is back in jeep. Everything that was done, both sets of guides replaced, head rebuilt, exhaust seats were checked good. Exhaust valves changed. All new springs for intake and exhaust. All back together. Cold compression is 120 all four cylinders. 125 hot. 25" of vacuum steady at 700rpm. Thanks for all advise and help out there. Glad to have the old willys back together for now.

    Glad you got it fixed.............although when you said " exhaust seats were checked good" are you saying they did not grind the exhaust seats when changing exhaust valves and guides?

    Hopefully the oil situation is taken care of too, that would aggravate me to no end.

    One of the best threads I've ever read in this here cyberspace. Beginning to end, failure to triumph and with a denouement.
