Xxchakalatexx Posted February 26, 2016 Author Share Posted February 26, 2016 Guess who is back?! Since the last update. I had the new vf40 installed. Got the car back monday night. Drove it a little bit that night and a bit the next day. And yesterday the car decided to lose boost and the check engine light came on, which i found out the code is P0011. I read through some old threads. But the new turbo only has 90 miles on it. I did a few moderately heavy pulls, but nothing that was extreme red lining, bouncing off the limiter kind. Now it sounds like the compressor wheel is scraping the housing. Should i go for another turbo or rebuild that one. Any clues what the P0011 is? Possible oil clog at the banjo bolt? And it didn't start making the noise until after i was sitting in traffic not while i was accelerating Link to comment Share on other sites More sharing options...
JmP6889928 Posted February 26, 2016 Share Posted February 26, 2016 Turbos fail for basically one of two reasons: Oil starvation or ingestion of foreign material You have a severe oiling issue. Potential bad oil pump but more likely a banjo filter did not get pulled and was at least partially clogged to start with. if you don't fix the oiling, it will continue to eat turbos like a fat kid eats cake.

Scruit Posted February 26, 2016 Share Posted February 26, 2016 90 miles and you're doing pulls already? That's not the approach I took - I stayed very conservative for 1k miles, never getting into any boost at all. Anyway, it is what it is. From here: I suggest you disconnect the downpipe and check the condition of the turbine bearings. Of course, turbo scraping noise = don't drive until you confirm it's good.

JF1GG29 Posted February 26, 2016 Share Posted February 26, 2016 As JmP said, you have an oiling issue. P0011 can be caused by low oil, incorrect oil pressure, preventing the AVCS from operating. Your turbo is not getting the oiling it needs (banjo?), so the journal bearing can't function as designed and wears incredibly fast. You will need a replacement or rebuilt turbo. But before you install a new turbo, you need to address your oiling issue.

Was you oil inspected for metal particles ? I had it done for me since it was under warranty. But now i'm doing it so i'll make sure it is done right.

Xxchakalatexx Posted February 28, 2016 Author Share Posted February 28, 2016 Pulled the turbo, in the process messed up a few bolts and bits. So ordering a new chra, nuts and bolts. The banjo bolt was pretty dirty i believe. But never seen one so that may be the cause of the p0011. Now my dad helped me pull the turbo and he said that i should get a new banjo bolt filter cause it helps with the oil pressure. Should i get one or not? And he also said i need to get the stock BOV cause that's part of the reason the turbos are blowing. Right now running 100% atmosphere. Is that true?

Xxchakalatexx Posted February 29, 2016 Author Share Posted February 29, 2016 Also have a vf46 instead of the vf40. Meaning i should probably do any upgrades necessary for the differences Link to comment Share on other sites More sharing options...

rmoore5 Posted February 29, 2016 Share Posted February 29, 2016 No, I still run the banjo filter. As I am the only owner of my car and have done all the maintenance myself I am confident of it's condition. A used car would need to have it replaced minimum, the debris in the oil system is what plugs them. That's my opinion for what it's worth. Link to comment Share on other sites More sharing options...
Merc6 Posted February 29, 2016 Share Posted February 29, 2016 Also have a vf46 instead of the vf40. Meaning i should probably do any upgrades necessary for the differences Nope, same stock turbo trim levels with some visual 5 Arc wizardry to make it "better than" the VF40. When you bump up to a VF52, (after all the issues are solved) you will then need an updated tune at the minimum. Banjo filters removed with the one right at the turbo being the High Priority one. 2005 Satin White Pearl Subaru Legacy 2.5 GT Unlimited 5EAT (Project Car) 2019 Agate Black Ford Explorer XLT 4WD (DD) Link to comment Share on other sites More sharing options...
Max Capacity Posted February 29, 2016 Share Posted February 29, 2016 Well that banjo with the filter is not at the turbo, its on the back of the head.

Xxchakalatexx Posted February 29, 2016 Author Share Posted February 29, 2016 Yeah filter is out. I'm just deciding now whether to do an upgrade on the oil lines. Thinking about pulling the up pipe as well, after looking through old posts, gutting the up pipe would probably be a smart choice. And it's funny because i didn't even notice that a vf46 was ordered and installed until i pulled it and check the P/N. Link to comment Share on other sites More sharing options...

Xxchakalatexx Posted March 2, 2016 Author Share Posted March 2, 2016 Good news. Got the turbo back on. Made sure all the oil lines were tight and connected and same for the coolant. Waiting on the nuts still for the exhaust. Missing one on the up pipe and 2 on the down pipe. Mid pipe is still disconnected as i'll probably still have to remove the DP to get that back on. Reset the check engine light and primed the system. Started the engine and let it sit for about 5 minutes. I know i spilled coolant all over the engine and exhaust so there's a reasonable amount of smoke coming from under the hood and under the car, some out the exhaust as well. Once i get the nuts i'll be sure to bolt everything back up and let it run for a decent amount of time. I'm hoping there is no leakage. I checked but with the smoke it's unclear to see if there is one. Link to comment Share on other sites More sharing options...
Xxchakalatexx Posted March 3, 2016 Author Share Posted March 3, 2016 Anybody willing to tell me how i know the turbo is getting oil rather than taking the bolt off the top if the turbo. Link to comment Share on other sites More sharing options...
rmoore5 Posted March 3, 2016 Share Posted March 3, 2016 ^^That may be the easiest way, checking for oil flow on the return side is kind of hard to get to. Link to comment Share on other sites More sharing options...

Xxchakalatexx Posted March 4, 2016 Author Share Posted March 4, 2016 So is the vf46 supposed to make a whistle noise while building boost or do i have a boost leak? Link to comment Share on other sites More sharing options...
Scruit Posted March 4, 2016 Share Posted March 4, 2016 Should sound like a rush or air in a pipe - if the sound is very clear then it's probably external = not bad. Link to comment Share on other sites More sharing options...
