Oil on my turbos(and other fun problems with pictures!)
I'm going to be installing a downpipe this weekend, so I figured I'd like to fix my turbo problems as well while I'm up in there.
Here's the pics of the oil on the turbos. I'm not sure where it's coming from, but it smells awful when I stop and it's all burning.
Also, my boost pattern is pretty messed up. It seems to be 9.5-4-6. It might be 10-4-6, but the gauge seems to be reading 9.5
When I pressurize the system, the only place I could find leaking air was right in the picture below..however, I still heard air rushing out, but I'm told it can also just go through the engine and out the exhaust...
If you look at the picture, the little nozzle stuck in a hose right below the blocked upper intake...air was coming out of there, which I'm assuming it's not supposed to. BUT, I'm pretty sure that's for my primary turbo, which seems to make boost just fine.
Lastly, my gauges have absolutely lost there mind.
About 3 weeks ago, I took the whole gauge cluster apart because it wasn't working. I couldn't find anything wrong so I just hooked it all back up. All of a sudden, it was working perfect. Worked like that for about 2 weeks. Then a week ago the needles started working, then not working. Then it got worse and worse.
I filmed a video of the gauges : http://www.youtube.com/watch?v=O96dXeCQGW4
That was right before they went out permanently again...notice how crazy and sporatic the gauges are. Hitting bumps and playing with the connectors does not seem to make a difference. When I hit the secondary turbo my check engine light comes on and gives me a speed sensor warning, but as soon as the gauges come back on the light goes away...
Anyways, that's all my issues for now...if you have any idea, let me know since I'm changing the DP and I'm going to have good access to the turbos.

That gauge problem might be grounds or excessive/unstable voltage there's a thread about re doing the grounds for the cluster and main engine to frame ground.
Ive seen that gauge problem happen when the battery is either un secure or toast. Start there.
Air is/might be leaking from the internal waste gate on the turbos. Its common and might explain your boost issues. That oil is proablly from the turbos themselves but might just be the gasket for the oil pipe.
