I'm not losing any coolant. It smells like burning oil. I checked around my oil sending unit but I think it's giving me an honest reading just based on how much oil I truly am losing. I have constant blue smoke now, instead of just when accelerating. Can you point me in the right direction of a diagram of my turbo?

I haven't lost any power which is kind of throwing off any troubleshooting on my part. I'm losing excessive amounts of oil, constant blue smoke, oil beneath my oil pan and running the length of my exhaust.. though I can't tell if it's coming from the hole or not because I have no way of lifting my car. My exhaust pipe itself isn't dripping anything but the back of my car is covered in oil droplets.

Thank you for your response!

Head gasket may have failed at right front putting oil in #1 cylinder and chain vault. Remove plug in exhaust manifold at #1 and start engine. Oil may come out

Remove the aluminum tube that crosses over the top of the valve cover. This is what connects the turbo and the intake manifold. If you find it's wet with oil, you have a bad turbo seal.

Thanks guys! I will give these things a look tomorrow, and if you have any other ideas please keep throwing them at me. I would really hate to have to sell my car as a mechanic special.

x2. This would account for blue smoke.

You can barely see the oil cooler lines from above. They hug the block from the oil filter through the engine mount arm then head for the area behind the bumper below the headlight. In the second to the last picture, there are two big metal lines that change to rubber as they go from behind to under the AC compressor. That's them.

Oil on the AC hose could be spray from a worn power steering pump seal (wipe the back side of the power steering pump pulley) or a worn front crank seal.

The top line in the 5th pic (possibly power steering return) looks cracked but not leaking. You'll want to order a replacement when you buy parts. It is 12mm on the SD. I'm guessing the same on a SDL.

So I haven't removed it yet, but I figured I'd let you know, the metal tube that goes over the valve cover actually weeps oil at the seam. I found fresh oil pooled on my oil cap as well as on the hose that comes out of the valve cover.

I will take it off today and see what's going on inside. Do I need to completely remove it from the turbo side?

I think at this time what I'm going to do is buy some cleaner for under the hood and oil. Then I can clean it all down, fill it up, start it and see where it's coming from (hopefully)

Two bolts hold it to intake manifold and one holds it to the mixing pipe above the turbo. It should pull up and off when the bolts are off. Mind that the mixing pipe is angled so it takes some wiggling. Set a rag under the intake manifold seam to catch the gasket. I reuse it with a smearing of RTV. I've never seen the big green o-ring on the mixing pipe look anything but good.
