I love how subtle it is, but how much that amount of tint does for the car. looking great

Anything change with the puffs of smoke? I still have this issue on my car as well

Some of the prevent diaphragms cut off vacuum when too much is being pulled letting no PCV happen. I think this was some sort of revision done for EPA with in the last few years.
You can take it apart and rework it. I'd run 2 stage PCV system. A bigger hose for evacuation from the Valve cover, Provent, then evac valve ported just after Air Filter. Then a smaller 3/8 PCV valve from intake manifold tee'd into the evac hose so the provent will catch the vapors.Comment

Not much has changed lately. Since the last update I have cleaned up the turbo oil drain setup by welding a larger hose barb onto a 10AN female fitting and installed a larger PCV hose via a VW oil cap breather. I have run up to 18psi of boost and it's a fast car, but because of the issues I've had it still hasn't hit the dyno. The exhaust still smokes, the plugs are still a little oily, and the engine still makes a lot of blow by. I confirmed the problem is with the rings by running the engine briefly with the turbo held stationary and the oil feed line disconnected from it to rule out turbo drain issues. I don't know what exactly is wrong, honed incorrectly or with the wrong grit? Too much piston to bore clearance? Needed rings after what happened before? (they weren't replaced). I don't know, I just know that I had to pay to have it done because I was running out of time and I paid dearly for that.
The AC has also been giving me nonstop problems. I never could figure out why it sometimes shuts off in traffic if not on position 4 and will not come back on, and the issue has only worsened with time. It eventually leaked down too and I can't find evidence of the leak so it might be in the evaporator box, or it might be under the heat shielding. The clearance from downpipe to AC lines was never what I wanted it to be but I did insulate. Add that to the to do list along with rear suspension bushings, steering linkage, new rear tires, and upgrading to B58 coils which I hope will solve the miss I have at over 6,000rpm.
This car is cool, but it's a major pain in my ass that hasn't lived up to the intent of the build at all. The only person who ever said that the smoke and blowby might just be par for the course with forged pistons in what is essentially a race engine is the person who did the work, nobody else I've talked to about it has agreed that this much blow by and smoke is normal for a built engine and I personally haven't seen that and I have seen (and even tuned) a lot of cars with built engines over the nearly 20 years I've been into cars. All very disappointing and because of it I haven't had much fun here and that was the whole point.Comment

Sucks the engine has been such a PITA.
Regarding engine smokage, I had an old loosey goosey drop in from the top uncoated 2618 JE piston 4g63 that sounded like a tractor and didn't burn or smoke a drop despite a ball hone and loose top ring gap (iirc in the ballpark of 50thou+)
Did they rehone and then use the same rings? The only time I've done that was on an EJ25 in a pinch and it definitely burned oil/had blowby on the hole I did that on to get me by.

Thinking the only way to fix this is to take a weekend, fly to the everglades and attack this block together. New rings, re-hone and put back in.
Still chewing my nails off as I have not started my rebuilt engine...Comment

When I dropped the engine off at the shop my request was just get whatever it needs, I was told it did not need new rings after it was inspected and since they only had about 80mi on them it made sense to me. It got honed and rebuilt while I was out of town and I picked it up and reinstalled.
Haha, your tickets would probably cost more than having an engine shop (if I can find one I can trust) and having them do it. A potential engine rebuild for this car is so far down on the list right now that I don't see myself having time for it in the next two years. This wagon, my E30 and my RX7 all have a list of stuff that takes precedence over rebuilding an engine because smoke makes me mad.Comment
