Oil pump is whatever FM puts in when they build a 2.0L motor for you.

I can drive around and go down hill with huge vacuum then accelerate
without going into boost and don't see blue smoke in the rear view. Seems like
high vacuum would suck in oil if it was valve guides. It also doesn't smoke
noticeably when I first start it up or just let it idle. It smokes quite a bit
of blue smoke when I go into boost whether boost was proceeded by vacuum or
not. PCV removed and replaced with a hose to the catch can doesn't change
anything. no blowby in the breather catch can ether. No oil leaks around the
engine, oil is going out the tailpipe. Cylinder #1 shows a fair amount of oil
contamination on the plug and the top of the piston and none of the others do.
I don't measure bad compression or leakdown in any of the cylinders and it
doesn't feel noticeably down on power, dynoed at 338 hp with good and slightly
conservative afr.
I replaced valve stem seals on the intake for cylinder #1 without removing
head. valves seemed reasonably tight in the guides when I wiggled and spun the
valves by hand. I saw no glaring issues. no change in tailpipe smoke though.

Did you have occasion to replace the oil pump or modify it for greater
pressure?
