Smoking exhuast (yes ive done my R&D)
So this is now Twin set #3 and the car is STILL blowing smoke out the back. It's killin me because I can't seem to find an answer...
I have the top nipple on the oil neck attached to a breather and the lower is open to atmosphere. The car is non-sequential, so that should help a bit with the diag. Can anyone give me a reason as to why 3 sets of turbos would produce the same pattern? I have no PVC just as an FYI
Yes obviously if the turbos are bad they would but I have obtained 2 sets that were off of reliable FD's that did NOT smoke previously... HELP
Now interestingly enough when I put the breather on the top nipple and let the car idel for about 10 minutes I noticed the smoking was so minimal you couldnt really tell if it were oil or black smoke... but when I drove the car in that state as soon as I got into boost (5psi) upon deceleration... blue oil smoke out the ***...
Looking for a remedy.

how much mileage on your engine ....?
a rebuild is a good place to start if this is not a turbo problem .. it`s an engine problem
you might have some very tired oil control rings ( unlikely but possible ), oil control ring seals ( most likely ) , or oil control springs ( very very very rare that this happens .01% chance that they no longer do their job )

Check your oil and see if its the consistency of gas. If your oil seals are failing oil will get into the combustion chamber. And unburnt fuel can get into your oil.
Yeah, quite possible you have bad oil seals in the motor - not super common on the FD, but it does happen.
The one good thing is it means the inside of your engine has been really well lubricated
. I've rebuilt a number of FC motors that had bad oil seals (some of them had NO oil seals, they had totally disintegrated) and the engine internals were in gorgeous shape. After the rebuild they were VERY strong runners.

but if the seals inside were blown wouldnt the car smoke all the time??? Dale how far are you directly from Tally? If I brought the 7 to you do you think you'd have a day to help me out with troubleshooting it?
Also since the PCV has been deleted, would reinstalling it solve the issue???

well if the seals are bad but not gone they could still withstand some oil pressure and not let oil by right away but as soon as you boost ( high rpm`s ... = high oil pressure so it lets some mix in within the "chambers" that are not under pressure ... the oil will sit a bit in between the oil control rings and the side/corner seal are untill it gets a chance to get sucked in in the intake stage
try revving the engine with no boost, any smoke
but really for blue smoke there are 3 main possibilities
turbos seals are bad
severe oil infiltration in the intake tubing ( drenched ) ( repair the PVC / eliminate it ..or might need a catch can )
bad seals/control rings
you have eliminated the turbos .. so the problem must be withing your engine unfortunately
but .... it is blue smoke you see right?

Correct blue smoke... and motor was rebuilt 6 months ago.
See alot on the car was deleted on its way to being Non-Seq... And the car was running fine when the PCV was installed ( Why I deleted it was probably ignorance on my part ). So now's it like ok how the hell do we stop this damn thing from pressurizing into the exhaust, because there isnt any oil in the intake streams anywhere...

Trending Topics
i have seen on extreme rare occasions ... oil control ring springs .. incorrectly installed ( they are directional ) and the way they were installed was such that it did not force the oil control ring to spin with the rotor but rather within it which caused the seals to wear out rather quick .... allowing more than the regular amount of oil mix with the combustion mixture
also try venting one of the nipples ( the horizontal one ) to the primary turbo intake and add a catch can on that line

This is a shot in the dark.
I've seen FD's run on bad turbo's for a while and after replacing them they still get oil burn out the exhaust. Ironically, it had nothing to do with the new turbos as it was left over oil in the intercooler. Like I said, it's a shot in the dark, but it has happened.
Try taking off your intercooler and spraying it out really well, along with the piping. Did your original turbos that went south leak a lot of oil?
Good luck!

Ok so new developement... Hit advanced auto today and got a brass pcv valve. The car seemingly does not smoke nearly as much as it did before. I mean its actually drivable now. It seems at times im puffing black smoke (fuel) and then at time its puffing blue smoke, but as I said its maybe 10% of what is was previously doing.

ok false alarm car is still smoking ... this is really getting to me... i swear I just wanna get rid of this car and let someone else deal with it... $8,000... why not. Anyone anyone... lol
Ok if anyone has any words of wisdom for me im open to them... This is killing me.

ok
i'm just gonna put this on hold for a second and say take a look at it again.
the smoke i am seeing is puffy and disperses in air which to me looks more whitish than blue. what does this mean? condensation, as in water being burned, the thicker it is is due to coolant in the mixture hanging in the air longer.
so does this blue smoke have a sweet smell to it? does it really dissipate in the air fairly quickly as i'm seeing or does it really hang there and float away for a good distance? burning oil will sit there and not go away until it basically mixes with enough air that you cannot literally see it.
i'm leaning on this is a misinterpretation of a bad coolant seal and you're just looking in the wrong area. follow the coolant system checks instead for the time being or better yet just do my testing method:
1) warm the engine for about 5 minutes to semi pressurize the cooling system but not hot enough that the engine is scorching because you will be working on it
2) pull the spark plugs out and dry them with some carburetor cleaner and compressed air, older plugs make this test easier to verify instead of brand new ones
3) reinstall the dry plugs
4) remove the main relay by the battery
5) crank the engine while counting to 5 then stop
6) remove the spark plugs immediately and inspect them
result: dry and clean as you just reinstalled them means you probably are safe but you can re run the test while pressurizing the cooling system to 13lbs if you have a tool to do so resulting in a more accurate test. if any plug is wet and does not specifically smell like fuel then you likely have coolant getting into that chamber. some engine only leak internally when cold, some only when hot so varying the test may yield the problem either when cold or hot but more typically internal leaks occur more on cold engine than hot as heated metal expands and seals better.

Ok so I pulled the filler cap and here are the results... and they don't seem to look good. There is clearly condensation getting into the oil filler somehow and that says to me water/coolant leaking in... I say that because the cap has small beads of water on it and also in the filler neck there is foam/cream and that says condensation also. As I look at the video clearly the smoke is white BUT the crazy thing is that when im driving its black and it does not smell sweet at all nor is my coolant level dropping....but my oil level apparently is dropping...
Black = Gas
Blue = Oil
White = Coolant
If this is correct then can anyone explain wtf my FD is doing???

You have the smoke colours right. it want's particularly cold that day when you took the vid right? I assume it's not that cold in FL. How much is your oil going down? can you basically determine that you are burning oil and not coolent?

actually it was about 50 outside... so I know that doesnt help much. I just took another video so it should be done in a few.

This was after I removed the oil filler cap and let the car run for a few.

Put your hand in the smoke near the tailpipe for a minute or 2. If it comes out oily, well, there's your sign. If that was coolant, and at that amount of coolant, you would have to be dead to not smell it.
That looks like a rebuild to me, because I have never seen that much smoke from a turbo leak at idle.

ok so explain how a 6 month professional rebuild yields this all of a sudden??? When I say a sudden yeah it smoked for a little bit but all of a sudden it just came out of no where AFTER I pulled the pcv off the car...
Not saying its time to rebuild but something doesnt make sense in the way its driving. I'll see if I can get more vids of the car in motion.

Anyway I am probably wrong on this... just a suggestion
Edit: Just realised you are running an open system and catch can, so that can't be the reason....
