    not that hard if you have the right equipment and you have welded before.

    I will get the specs on that welder tomorrow and maybe you can help me figure out how to set it up right and which settings to set it at.

    Yup, straight argon at about 25cfm or so.

    sounds like your using a flow gauge, i use guages at 10 to 11 pounds. holes are cause by unclean aluminum, too much air pressure, and the angle of the torch. the tungsten should only stick out as far as the openig of the hole of the ceramic cup. if you get aluminum on the tungsten it does that too. tungsten has to be clean and ground to a point.

    Hmmm...I'll try changing the tungsten again and setting the flow down a little bit and see what happens. Thanks for the advice.

    I guess I am gonna rip her apart this weekend. I am assuming that I have more internal damage than external damage. The area that the cracks are is under the crank which would be suspect to a broken skirt at some point. The problem is that the trans oil is leaking from it from that point when full. That would tell me their is cracks internally allowing oil to seep into the crank area which I would assume is not good!!!! ???
    Its amazing that this engine runs so strong with this issue. I do not notice a lean condition as the plug looks good, and I am not building any pressure in the trans area as I have no build up on the new vent hoses.
    I guess its time to look for new cases or see if these can be welded. Anyone have a spare set they want to part with? This machine is most likely going to be parted on Ebay as I will not drop $600.00 in new cases.

    Check your cases before you give up on it. I will bet they are more than repairable. I've seen some really bad cases repaired before in the crank journal and when its done right they are just as good as new. You still got a steal when you got that R, I wouldn't give up on it yet. I've sold cases in your condition for big money to so you can go that way to, then you wouldn't have as much into new cases. There are alot of guys on ebay that would buy those case halfs and repair them. I think I got about $200 out of my last set I sold and they had cracks in the crank areas. You can get new case halfs at service honda for $472.54 plus shipping

    Im gonna see what they look like when I get it apart. The machine was a good deal and I know I could easily get out of it what I have in it. I need new front calipers now as my brake issue is caused by excessive movement that cannot be compensated for. I was actually able to flex 4-4" C-clamps when testing the system. All is good, but when mounted up, they are hardly there. I replaced the slide pivots and all seals again. Same thing, so there is another $100.00 for an unknown, hopefully good used set.
