    Sagas being what they are, ... this one continues.
    This is a picture of the engine mount for the model IV on the engine. Is this water tube threaded like the one I heated up on the cylinder and can I orient it to effectively clear the offending member of the engine mount system?

    Yes and yes. One of them has to be clocked at a different angle than they come from the factory at on the 7SS installation with a new ULS engine also. You need to carefully clean the threads and use the correct retaining compound when reinstalling it at the needed angle. You've probably already been through that and aware of how it's done, I guess.

    Thanks. I"ll just have to be careful in that area with heat I think. there is an oil seal under the water pump impellor. I"m searching the heavy manual for info on removal. P.S. your up late. Thanks for the quick reply. I"m tired.

    Yep, up late... trying to get ready for a road trip up to Montana before Oshkosh. I believe you want to remove the housing that the tubes are connected to from the rest of the pump, before you have to apply heat and do the job. It should come off clean and allow reuse of the gasket

    I re-clocked many of my water fittings and replaced a few with other angles. As John said you just remove the offending parts to heat them. It doesn't take much heat at all. Here's 8000 words:

    Ok Im back at it. I took some time off to handle my ranch and other sundry duties. Now I can concentrate on the engine install. I took off the water pump housing to remove and re-clock the water elbows that were pointing at the engine mount vibration isolators. I got one out, the other is stuck. I heated it to 200 degrees with a heat gun, it turned about 90 degrees and stopped. Any ideas, or is it a pretty sure bet that it is galled and unusable.
