I restored a 1967 T100C several years ago from the ground up. I have ~1000 miles on it as of now, but from the get go, it has blown what seams to be clean oil from the left exhaust pipe. This runs down the side of the head and also down the exhaust pipe. It does smoke, blue. from that side somewhat. Did I get a ring upside down, or could the timed breather valve be off? Thanks:

I'd suspect a cracked oil scraper ring or a too-large inlet valve guide or a guide, inlet or exhaust, loose in the head.
