You may be using the wrong timing system 700 1990

OK. So I couldn't wait any more and found the time to go and take another look at the car. I think my initial emphasis on the turbo may have been a bit preemptive but I have some more info which will hopefully reveal some truths.

I checked out the FAQ to try to identify the turbo and think it might be the first one the page, the Garrett T3 but I'm not positive. I inspected the entire unit and found a a loose hose clamp and a hose that is completely disconnected, I'm not sure if intentionally. There is a large hose which leaves the turbo and goes into the piece in front of the radiator and then out the other side into the intake manifold. This hose splits with a small hose and directly out of the side of the smaller hose, making a "T" is another small hose that simply ends. I searched and searched but couldn't find anywhere it could connect to. The rest of the turbo, although not without a bit of oil, seems to be hooked up securely and in the most logical way possible (the hoses couldn't perceivably connect anywhere else better).

The fluids in the car are all good. The transmission fluid is high because I took a guess refilling it and didn't want to be too low. It a cm/cm 1/2 above maximum cold so, prob a bit higher hot but I'm not moving the car. Going to drain it next time I'm there.

After checking all connections. I started the car to see what I could see. The engine runs beautifully and idles great. The exhaust is completely invisible and doesn't smell irregular at all. I let the car heat and didn't see much of anything out of the ordinary. The I had a friend raise it to around 2500 rpm and the engine continued to sound good and accelerated fine but immediately, and I mean immediately, the smokey substance began to come out of the top of the exhaust manifold. It kind of weasled out and then produced a steady stream becoming more noticible. It was a grayish color, kind of white, kind of gray and just with a general car smell about it. Then I noticed it coming from the flange where the turbo connects with the exhaust manifold and, to a much lesser extent, the connection between the turbo and the exhaust leaving the engine compartment.

I thought it might simply be exhaust but my exhaust was completely clear and this was very visible. Also, I tried quickly capping the tailpipe with my hand to see if it would increase the flow of the smoke by increasing pressure and it didn't. Not knowing where to go from here I killed the engine and this escape continued for another five minutes or so without the engine running, slowly disappearing. I touched the turbo and the exhaust pipe many times while the car was heating, while it ran and afterwards to see if the turbo seemed hotter than the exhaust and they always seemed to be of a comparable and reasonable temp.

Since the turbo was never disconnected from the engine and both were running without this problem before I am at a loss for knowing what's going on. Also, just to repeat, the engine starts with ease, sounds great and idles well. Any thoughts?
