    ." I was raised that cresent wrenches and pliers were a no no on hex nuts, bolts etc. I can still hear the voice in my head as I bet my daughter can as well. "

    Steve about the "voices". My first Shop Foreman was from Rolls Royce and made me take home my Cresent wrenches. He said that even having one in your tool box at Rolls Royce was grounds for Dismissal-Holey Moley
    I still hear his accent when i see one, lol

    I used to feel the same way until I got a Klein adjustable wrench. The jaws are truly parallel and remain so under load. It's still my tool of last resort but it does have its uses.

    Tractor supply has a double ended box wrench for trailer hitch ball nuts. The one end fits my O290 drain plug.

    Steve, how much do you tighten the the an fittings into the oil cooler? Im guess since it is iron pipe threads you can torque them down pretty good.

    I don't know a specific torque but they get tight especially when you get it clocked into the needed position. Check the torque on those oil cooler mounting nuts. Had an oil leak up front ona Tri-Pacer. When I got to looking I found the mount nut was loose. It allowed the bracket to wear a hole in the oil cooler causing the leak.

    You can see the worn hole via the light behind it.

    The torque is in the overhaul manual. I think Steve posted it on the siteIMG_0827.jpg

    The oil cooler nuts were loose tighten them up. Used aviation permatex #3 form a gasket for the oil line threads.
    I ended up torquing them to undetermined torque because of the angle at which I need the oil line to clear the exhaust cross over. It was tight!.
    No more oil leak. On to the next project.
