Time for a new engine?
This happened shortly right after the oil feed line from Flyin Miata sprouted a leak.
It's a FM voodoo2 kit

My guess is either a piston ring, or maybe a oil seal in the turbo?
I ran a compression test, got about 135 on each cylinder.
The motor doesnt knock or make any loud noises, but it acts like it is running on 3 cylinders (shakey).
It doesnt really smoke until you put load on the motor.
The intake tract is full of oil, I haven't taken the intercooler off yet, but I am sure it's got a **** ton of oil accumulated in it.
Time for a new motor?
Or could it be the turbo's oil seals?
Think FM will feel any obligation to repair the turbo (If that's the problem) for sending me a faulty oil feed line? Is that just wishful thinking?

you're most likely blowing oil through the crankcase through the rings, sounds like something in there is seriously damaged. Was the compression check done with the throttle WOT?

The throttle was wide open when I did the tests. it hasnt been more than 1000 miles, I havent driven it since early november.
The line was leaking from the crimp.
Here are some more pics.

as you can see there is oil all over the place, when it's running you can see it bubbling out of the down pipe and actuator arm.
Keith I will call you guys as soon as I am with my unlimited long distance phone..

the oil is most likely entering the intake from the crankcase breather....which means a few things, one is easy, the pcv is no sealing in boost, but alas, you motor sounds like ***, so i assume you have major blow-by from failed rings/ringlands.

I forgot to mention I disconnected the line from the valve cover to see if oil was blowing out.. not a drop, the oil on the dipstick is crystal clear, there aren't any metal flakes as far as I can tell..
Could that mean the oil is coming from the inside of the turbo?

ive had that problem before my engine went out on me, when you drive the car at full throttle does the oil guage jump around very badly and not stay steady ? thats how i knew it was my rings.......
also take the intake off of your turbo and crank the car ( if you can ) and see if oil is comming out of the turbo, you may have blown the seals on both sides of the turbo.....
done that aswell.... mine was cause from all the pressure from blow by going through the crank and into the oil feed line.......

You think it could be this:
Turbo seals somehow went bad so a lot of oil went into the intake tract and maybe coated the spark plug so that it has a difficult or impossible time firing that one cylinder?
Just shooting ridiculus idea's out of my ***. If that is the cause then the only thing that needs to be done is clean up the oil, rebuild that turbo, and change the spark plugs. Prolly wishful thinking......

Looking at the pictures, I agree. The oil is probably fouling your plugs, thus the terrible idle. Call that a symptom, not a cause. Looks like bad seals in the turbo.
An oil gauge will often work as a knock sensor, actually. If you're setting the pressure jump around, it means you are in the process of damaging your engine.

One comment from Bill - there's supposed to be a 90 degree fitting on the top of the turbo for the oil feed. One was included with the kit. The way it's installed right now, there's a lot of stress on the line.
His estimate is either a bad PCV (that's a lot of oil for a PCV in my opinion, but it could happen) or you have hurt rings. Excessive oil in the cylinders will hide a ring problem.
Is that a piece of a PCV valve in the bypass valve outlet?

The PCV valve is brand new.
The way the oil line is run there is no stress on it whatsoever???
The turbine shaft doesnt have any play at all.
The turbine will coast for a couple seconds if you spin it
I found the cause of the poor idle:
oily plugs...

I have no idea how this happened, but I have a feeling it was the cause of the suby noise.

Here's a video of it running now:
http://www.youtube.com/watch?v=zmBeCkzgo6o
It sounds perfectly normal now, it wasn't smoking at all after I changed the plugs, so i took it for s short drive down the street. It feels as powerful as it ever did. I got it to boost up to about 5 psi ( I didnt dare go higher) without any problems.
So now the only problem is the mass amount of smoke.

It may be running better now that you have all four spark plugs, but again there is only three ways you are getting oil in chamber like that....blow-by, failed pcv, failed turbo seals. I highly doubt the turbo, you say the pcv is fine, and the compression test suggest your rings cannot hold compression like they should (especially when saturated with oil).
