I thought I had more pics in this thread, I guess not. My bad. I am a firm believer in a pic being worth a thousand words...
To recap, on the trip from SDAC 26 to Cali it used a quart of oil per tank of fuel. Upon teardown I found oil in the intake manifold #1 runner(like a puddle) and the #1 exhaust runner on the TU header was COATED with burnt oil. I used a scroll cartridge to 'port/polish' the coke outta there it was so thick.
Thinking the newly built head (all new guides, valves, springs, seals) would solve the smoking issue I was bummed to see it still smoked. So 15 minutes after getting it running again my Bro found the huge vacuum leak from the intake manifold nipple to PCV valve. After that changing the PCV valve 3 times(including running the all metal Supra Turbo PCV valve now) I've tried restricting the vacuum source, closing it off completely, restricting the oil feed to turbo source, reconfiguring the oil drainback from the turbo, pulling the valve cover and resealing the baffle etc etc. All these 'fixes' with no real improvement. The #1 plug is the only oily spark plug now after 150-200 miles with new head. I haven't pulled the turbo or the head again and don't want to if I can find some other fix.
Could it be a piston/ring? I suppose, but the piston tops and the bores were PERFECT when I had the head off. For sure hindsight being 20/20 I wish I had taken the time to pull them out and inspect the rings but this was a sub 3000K mile motor and I just didn't think there was a problem there. Also the motor DOESN"T huff at all out of the oil cap when running so its not a top or second ring for sure. Oil rings? I guess but why is the problem intermittent/ related to high vacuum?
There's something I'm missing
