Blown Turbo? Please Help
Ok so since I started my 1st turbo build months ago, pretty much everything that could have gone wrong....has. Including a fire which toasted a lot of parts.
Here are my symptoms.
Loss of power
Oil in the intake
Oil in the pipe from Turbo to IC and TB to IC.
Lots of white smoke instantly coming from turbo area on start up.
No smoke at idle
Lots of smoke at any kind of revs and no matter the engine temp.
My setup
2000 ls 1.8
7psi
16g turbo
FMIC
EMU
There is no coolant under the filler cap. I made a catch can but havent tried it yet to see if my PCV valve wasnt working at all in boost.
Everything has gone wrong with this car. So I just need some help gettin through this one. Thanks again

Have you verified the condition of your PVC valve?
Is your valve cover breather line routed correctly?
Is your turbo mounted correctly (WITH THE OIL FEED AT 12o'clock and drain at 6o'clock?)
How is your drain mounted? Tap the pan beneath the turbo?
It'd be awesome if you took a couple pictures of your setup for us.
What was the condition of the turbo when you bought it? Used? Mileage? Previous application? Was there any shaft play?
Brain is right, it sounds like over-oiling or under-draining... but could just as easily be blown.

PCV was working but wasnt upgraded to handle the boost
Valve cover breather only has a filter on it..not routed anywhere
Oil feed/return at directly 12 and 6o'clock
The pan is tapped on the opposite side of the turbo.
There is a very slight kink several inches under the turbo, but if I press on the side of it to get the kink out and rev the car it still blows plooms of white smoke.. Otherwise the line is not restricted in anyway.
Turbo did have shaft play, I bought the entire kit off of here and every part of it has been either broken,lost or not working well.
SO I rebuilt it at home and got rid of the shaft play.

you may very well be the world's first turbo miata to have his oil return on passenger side.
Oil return lines are supposed to be mostly vertical. Straight up and down. When the oil comes out of the turbo, it's a little foamy and not pressurized, it needs the gravity to fall.
Combine a bad oil drain with a home brew rebuild, and I would think there's a good possibility that you're blowing by the seals.
The good news is, most of the time, if you fix the oil drain quckly, the turbo will be ok. You might shorten the life expectancy, but it'll recover..

I dont know if it looks a lot different on a 1.6, but on my NB I have ALOT of stuff in the way from the frame, cooling, and power steering. How do you drill and tap this hole without removing everything. The weird thing is how quickly it will blow out smoke. It will be cold motor and started only a second or two earlier and it will start plooming smoke. Can the oil really drain/heat up and the burn that quickly?
