Another “why is my Evo smoking” thread
Rundown of my car..
06 Evo 9 - 59k Miles - Stock shortblock - built head
My catch can setup is just a 10an hose coming from VC to vented can.
Precision 6466 gen2 BB turbo. Turbo has the restrictors in it from precision. Feeding from the head, and running the 10an g series stm return line. Turbo has normal shaft play.
Valve seals were replaced about 2000 miles ago with gsc heavy duty. I have nothing in my catch can. If it were rings, wouldn’t I be getting some significant blow by?
The car seems 2 smoke on 2 different occasions. Usually when I crank on a cold start, it doesn’t smoke until I pull out of the driveway and get about a block down the road at a stop sign then I see puffs of smoke coming out. 2nd scenario is occasionally (not all the time) after barely getting into boost and letting off on decel it smokes pretty bad. It’s definitely a blueish smoke. (Oil not headgasket)
My stock motor is being pushed right now but runs fantastic aside from the occasional smoking.
Is this just one of those - “you’re making over 600whp on the stock motor with a otw turbo, you’ll have to deal with some smoke” scenarios?
sorry for the long post. Just looking for some info.

Those compression numbers are normal for a IX with aggressive cams. The pictures shows your oem pcv valve still in place which is good. I wonder if it's stuck closed.... How often do you top off oil?
Is the turbocharger near level? Standard placement kit? There was a local guy with a custom FF kit that had some oil draining issues a while back. His turbokit had quite the lean to it and may have been clocked incorrectly.
I would check a few things. Leakdown test. Crankcase pressure test cold at idle and then once warmed up at WOT. Some things get tired over time or need more crankcase vent.
You could also check oil pressure going to the CHRA. Some of the Honda guys have restricted their turbo's slightly until the smoke went away.

It’s hard to gauge exactly because it’s not driven every day but I would say I pour half a quart in before changing it at 2500-3k miles. Oil level really never drops much.
Its an ETS forward facing kit. Here is a picture of the day I installed it. Return line is at a constant decline until entering pan. i assume turbo is clocked correctly?
Turbo should be clocked similar to what Garrett recommends. It most likely is but when trying to address a problem its best to create a list and go thru it from easiest to hardest.

This may also be helpful to watch.
You can also pull the exhaust manifold off and see if any of the ports have oil coming out of them indicating a guide issue.
Is the turbine or compressor wheel wet with oil?
The ETS kits come pre-clocked with the turbo bolted to the manifold, so, you should be fine there.
I would install a small pressure gauge in line with turbo feed, see how much pressure it's getting.
Also, how much is it smoking?

And as to “how much” it’s smoking. Not a ton. Sometimes it doesn’t smoke at all. Then sometimes I’ll stop and just see a good few puffs of smoke come by me at the stoplight.
He said that was replaced 2,000 miles ago. So the other thing left there are the guides (as some stated above). I'm particular on how guides are installed because it needs to be aligned with valve seats or recut valve seats to line up valves in new guides.
