So yesterday while driving, I suddenly lost all boost making abilities. All I would hear is a whistle/hiss. Soon followed a P0101 code and the car running rich and bogging.
Today checked my IC piping and MAF sensor to see if they were the culprit but unfortunately that did not fix my problem. Now when i turn the car in with the MAF plugged in, it completely bogs out. But when its disconnected every runs fine (except the fact that i still cant make boost).
I just took my intake off and snapped a pic of the turbo. There is oil on the inlet leaking to the fins and it looks like some rubbing.
Would appreciate y’all could offer opinions on the diagnosis and next steps. Thanks!
It’s most likely a boost leak. Most common point of failure is plastic end tanks on stock intercooler cracking. If you’re not stock your gonna need to do a boost leak test and check all connections between TB and turbo outlet.
If your turbo is on the way out but spins freely it should still make some amount of boost and probably noise.
That does look like more oil than normal in your intake. More likely from blow by than from the turbo though being intake side.
you can check your turbo for shaft play by pulling on the inducer shaft and putting a side load on it with your hand. Should t be much if any play. (Do so when cool)
It does almost look like the inducer might be touching the housing ever so slightly. It should not be touching in use.

I have checked all charge piping and intake piping on the car. I have yet to take the bumper off and check The I/C itself. From the underside the end tanks seemed fine but cant be sure until i take the bumper off.
as for my turbo, I'm sure it has touched at some point but when it spools now there is no odd noise of rubbing. Idk if its possible but I'm hoping it corrected itself by scraping the tiny bit of overlapping fin off.
still no boost and p0101. Car dies when MAF Is plugged in.
Anyways ill be taking my bumper off and posting pics of the I/C so stay posted!
Here are some pics of under my I/C. Both left and right sides. No cracking or leaks from what i saw heres. Atleast not enough to give me 0 boost at WOT.

Sir you were 100% on the money with your prediction. Left end tank has a huge hole in it.
