If you have the ability tear the engine down to a bare block before taking to the machine shop so you can inspect it for damage, like the cylinder walls/sleeve to ensure they’re still usable. If it is good then next I would have the machine shop see if you can use 87.75mm pistons instead of...
I would verify routing and check valve orientation as stated above, but there’s zero reason to have a vented can on the pcv side especially on a stock turbo (assuming that because of stock TMIC). Can you post a pic or your routing or which diagram you’re using?
