Boost leak help

[ZSHO]

The wastegates should be in the closed position AFAIK!
In your case it sounds like one or more wastegates are maybe stuck open or sticky wastegate.
The noise your hearing could be related to your issue!
I would also try to disconnect the PCM connectors and inspect the wiring harness for corrosion and clean it with some electronic or air mas flow cleaner.

Car wash (auto) or heavy rain recently! Z

wastegate at 100% is the pcm requesting boost and closing the valve to prevent movement of the actuator.
0.00 is rest position, or just wastegate spring only

(this is the way it was told to me)

Thanks for the reply and this makes total sense. I guess I was thrown off by a few posts on the other forum which said the c clip fell off their wastegates actuators and they had low boost. I thought to myself shouldn't they have high boost since the wastegates wouldn't open? Anyway I've ruled out the TBCP (TIp pressure sensor), the MAP sensor, IAT sensors, and the turbo charger boost solenoid, the BOV's, along with the lines that lead to the wastegates. I either have a big boost leak someplace (which I can't hear) or the wastegates are sticking open. I believe it's the latter unfortunately because the back one makes a weird sound when I artificially open it with compressed air. I've got an appointment at the dealer next Friday. I may have a local shop throw a boost leak detector on it first just to rule that out but I do have hot pipes and they seem Rock solid as I've checked the boots and clamps...

Wait a minute I think I get it...if the c clip pops off then the wastegates spring is still in play correct? So you'd see some boost but not only up to spring pressure...

Upon further review I've definitely found a problem. The front turbo wastegates actuator is no longer connected to anything...Its buried under the exhaust manifold and while I can get my fingers under there I can't get it from the topside by feel. It might be missing an entire pin and clip? Here is the only shot I could get of the end of the wastegate actuator attached to well... nothing from what I can tell  The rod also has play in it up and down which further adds to the it's not attached ..maybe I can get to it from the bottom?

Rent a lift?  That would explain a few things ..

That would cause a lack of boost LOL! Glad ya found it

 

[ZSHO]

Glad you found it! Is it still under warranty! 
Remove both Front and rear under- cover. PICS Below.  Z

C Clip

C Clip

Thank you!  I am going to have to buy some different sizes and see what fits but that should get me close.

Thanks Z!  It's definitely not under warranty (I had an extended warranty and I ended up getting my money's worth for it however it expired in June) or I would have just taken it to the dealer and let them probably just put a new turbo on it instead of troubleshooting it for so long.

Hopefully the C Clip will get this issue buttoned down & you can go rip roaring down the street again

So brief update. I jacked the car up as high as it would safely go then crawled under it. It was quickly apparent that while I could see  the actuator from down there I wasn't going to be reaching it easily as my car is a PP and the oil cooler is in the way. I drained my oil and took off the filter which gave just enough room to squeeze my big hand in there but just one of them. I was able to grab the lever but it was retracted too far to slip it back over the wastegate pin and with just one hand I couldn't pull it. So I enlisted the help of my 10 year old and my air compressor. He squeezed some compressed air in to the actuator and when it moved I was able to wiggle it on to the rod. Success I thought! But then I tried to put a new e clip on it and that was nearly impossible with one hand. That and I'm not sure I had the exact size I needed. Gave up after one hour of trying and some choice words...I am probably going to have to remove the downpipe which isn't the end of the world but this was not the 5 minute job I was hoping for thanks to that oil cooler...

Oh and there is an exhaust gasket right up there with very sharp edges. Ask me how I know...

At least your progeny sees you spilling your blood.  Priceless

Did you confirm that the turbo is in good shape internally?  No other issues that might just end up blowing the circlip off again?

I did verify that the wategate appears to be okay. I could get full wastegate movement with the compressor...but I didn't actually see inside the turbo itself so anybody's guess!
