update: i welded up th fitting on the input side of the filter housing, and drilled it to 1/16 for restriction. i put the gauge on the block, and went to town for a finer filter. as you may guess, they thought i was nuts, and they're books were really not much help. but i came home with the finest micron filter they had. i then took all the spark plugs out so i could spin it over and prime the oil and fuel pump. odd thing here, the oil gauge would pulse from 0 to 20 or 30, like there was a pressure loss on each revolution, like a bearing out? scared me to heck. so finally the big moment...i fired it up. it started right up and ran great !!!. i ran it for about an hour in my test stand. after all warmed up, no smoke, no blowby, all good. this motor was supposed to have been rebuilt a few thousand miles back, and a new owner decided he wanted a "belly button " motor instead (thanks ol ron for the term). so, rebuilt when, by who, and what did they do is not known and i have bought some rebuilt motors that were just new paint before. this one seems good, looks clean inside, so maybe i won this time. now, for some odd things and questions for the great minds here on the barn: my mechanical temp gauge i intended to use would not fit, so i went without. it will idle forever and not even show steam out the radiator top, but when i give it some rpm's, hot water will come to the radiator and belch out a bit, then as soon as it idles its fine again. like its not circulating at idle. 8ba, no thermostats, and just some old junky pumps i had for this test phase. comments please! now, the oil pressure once hot, was 10 lbs at low idle, and would peg the 50lb gauge at high rev, however, at idle it will sometimes still pulse (fluctuate?) bad gauge maybe? in 2010 i had a fire in my shop so my lifetime collection of junk for expiriments is gone, fire is a bad thing !! comments welcome, thanks skip
