That diagram is for the entire oil supply line feeding multiple items. The first several bolts farthest from the turbo ate the supplies for other places on the head. The turbo banjo bolt sits litterally on/inside the turbo not away from it.
Yes, there is a banjo bolt that attaches literally to the top of the turbo. But that's not the one with the screen in it.
 
Thats what weve been saying all along though. None on the turbo but still on the heads.

We didnt deny the fact that the screens were on some of the head oil supplies just the turbo one. The other thread specifically asked if there was one on the turbo feed line.

Definitely sounds like a case of multiple, different yet similar, thread topics confusion.

Well my motor is pulled and on a stand so tomorrow i will go and remove the banjo bolt on the head that goes to the turbo and double check but since i have already had this off while stripping my motor i am still pretty positive that it does not have any screen. I am pretty sure the only one that sis was my avcs line but i will tell you tomorrow. While a am at it i will be removing the screen on the avcs while i am in there as well as i never did for some reason. Also mine is a 2011 and that tsb says 2009 to 2010 so it may be pointless anyway.

The bottom line for these questions is: "is there an inline filter that is potentially clogged up and will starve my turbo of oil"? Isn't that the point? That was the OP's question. Aren't we trying to protect the turbo from oil starvation? At least that's what I'm worried about. And the responders to this thread have repeatedly said "there is no filter in the oil lines to the turbo". Which seems to be factually incorrect. The oil comes out of the top of the passenger side cylinder head, and passes through a screen. Then it goes towards the back of the car and supplies the turbo. It ALSO goes to the front of the car and supplies the valve timing system. But the point is that THERE IS A SCREEN BETWEEN YOUR TURBO AND THE SOURCE OF THE OIL. On 2009 and 2010 Foresters, it's in location "B" in the TSB.

So let me completely back-track and start again...

On the 2009 and 2010 (and possibly newer) Forester XT, is there a screen/filter that is part of a banjo bolt that supplies oil to the turbo? Is it possible that this screen is clogging up? How can I pull it out and replace or inspect it?

It seems that the answer is YES, there is a bolt screwed into the top of the cylinder head that filters/screens oil on its way to the turbo. So YES, there is a chance that it's become/becoming blocked, and should be checked. YES, it may be starving your turbo.

Next question: where exactly is the bolt, and how does one access it?

See photos

If anyone has pulled this bolt for a 2009 or 2010 FXT, while the engine was still in the car, please let me know. How did you do it? Did you remove either the turbo or the intake manifold? Or did you get to it by moving the intake duct over enough so you could get a straight shot at it with a socket entension? How long did it take you?

I agree there may be one from the block I didn't really check that one great when I was searching for my leaking oil bolt. However direct feed to the turbo does not have a screen and as far as my Subaru mechanic is concerned there should be no filter/screen anywhere on the oil feed line.

(However he has said a few other goofy things to so....I take it with a grain of salt)

I look forward to Nates discoveries

Quick - Nate has a 2011, so his discoveries may not be relevant to your 2009.

Secondly, I don't seem to be getting the message across very well here. Sure, the banjo bolt on the turbo itself doesn't have a screen. But upstream of that oil supply is ANOTHER bolt that DOES seem to have the screen. Who cares where it is in the chain? The fact is that it's there, and it's a concern.

Again, I don't get how this thread has gotten bogged down in the semantics of which bolt is which. If there's a screen in the way of the oil supply, it's a concern.

If you're in Ottawa, contact your dealer and reference the TSB I showed earlier (it's actually a Canadian TSB). It specifically refutes the idea that "they stopped putting the filters in".

I'll go one step further. I also have the Factory Service Manual, and even it specifically states that there is a filter in the union bolt that feeds the TURBO. See attached. They say you should check it for clogging. The FSM is for a 2010 XT.

I'm hoping top get at mine later today. Although I don't have a great feeling about my chances, given how deeply buried it is.

I looked at the Factory Service Manual for the 2011, 2012, 2013 and 2014 FXT (of course the 2014 is now the 2.0 Turbo).

The 2011 through 2013 manual have the exact same write-up on the oil piping with the filter/screen as I've posted above. So if the FSM is accurate, then they never stopped using the screens on the TURBO oil line on the Foresters.

The 2014 manual has no mention of screens in the oil piping section.

I've also included a little more of the TSB, with some text that describes how the piping with the screen is specific to the turbo. Maybe this will help clarify. Keep in mind the TSB is dated 24 August 2009, so there is no way it would include later model years. But that doesn't necessarily mean they removed the screen from later model years.

I'm droning on and on about this because we just bought this FXT, and I've been going through the list of all the stuff to maintain, as well as any problem areas. And in doing my original research (including using this site), I was led to believe that the screen thing was not an issue on my model year. So I was going to ignore it. But it kept bugging me that such a small thing could potentially blow up the whole engine. So I kept pursuing it.

Again, maybe the TSB and the FSM are both wrong all the way up to 2013. I never got to removing it yesterday. I'll definitely update when I do pull it.

Yes yes yes. We get the point that at some point in the line there may be a screen. I am simply stating what I personally have seen and heard from my mechanic. I am not stating you are wrong or anything of the sort. Sorry I will no longer comment on your thread now that you are potentially butt hurt.

Take care

Sorry motor is in the car now forgot about the banjo bolt so nothing to report on my end but as you said i have a 2011 so it may not even pertain to yours.
 
Holy cow this thread is getting ridiculous...

It matters alot as to where in the line it is. Certain places are going to have/require different oil flow speeds than others. Its just the nature of the beast when working with a fluid having to move through a system. I told you that I personally checked my turbo feed on my 2009, and they are NOT there. So unless the dealership has removed them on their own without telling me, then it never came with them in the turbo feed line.

I am honestly confused as to the point of this thread now. If you already KNOW the answer, then why ask the question?

Also, how many people do you know of that ACTUALLY messed up stuff from the banjo bolt filter being clogged? Now, of those people you know of, how many of them got avcs related check engine lights prior to the failure that were improperly troubleshot or ignored?
 
Finally got to the banjo bolt on my 2010 XT

Update: I was finally able to access the banjo bolt location that supplies oil to the turbo on our 2010. I removed the bolt and can confirm that it DOES have a screen/filter, just like all the Subaru documentation said it would.

So for those who are doing their own research, and who may have read or been told that there is no filter/screen on oil piping feeding your turbo on the 2010's, I can at least say that on my 2010, there was a screen, and I'm glad I pulled it to check its condition.

And from the Subaru documentation, it would seem that they used these embedded screens all the way up to and including the 2013 model year.

Do with this information as you wish.

There is a very long blog/thread on the site of allwheeldriveauto.com entitled "How to Make Your Subaru Turbo Last". This shop is run by Justin Stobb in the Seattle area. He is an independent shop specializing in Subarus. His blog page talks about many instances (I assume from real people) of turbos failing because the oil supply was restricted by a clogged screen in the banjo bolt.

How To Make Your Subaru Turbo Last :

I have personally bought parts from Justin and AllWheelDriveAuto, and he steered me through repairs in the past. His advice is solid and his Subaru-specific knowledge is vast, in my experience.

Here are pics from my car. The screen was pretty much squeaky clean on our car after 60,000 miles and unknown oil change intervals from previous owner(s).

Good luck, XT owners.

The point of this thread, from my perspective, was to confirm or dispel the idea that "Subaru stopped using banjo bolts with screens". The first few posts made it sound like late-model owners don't have to worry about banjo bolts with screens. I have found that to be untrue. So I needed to explore the topic more, and to pull the bolt on my own car.

If you want to use a fluid dynamics argument to avoid checking the condition of the screen on your own car (if you have this kind of banjo bolt), then you are free to do so.

Any farmer will tell you that if there is a blockage in their irrigation system - regardless of whether it's at the source, the destination, or somewhere in the middle - their plants risk being destroyed by lack of hydration.

Yes, there are specifically sized ports, apertures and fittings in the oil system, and they regulate and modulate flow. But if you clog up the overall flow, you're going to have a problem. At least that's what makes sense to me.


I don't personally know of anyone who has "messed up stuff from the banjo bolt". But I also don't personally know any other Subaru owners at all. So relying on my own personal sample size of zero would be useless. That's why I come to sites like this, and to allwheeldriveauto.com - so I can hear about problems and concerns from other Subaru owners and technicians whom I have never met. Then I take all that information, combine it with my own experience with mechanical things, and I make choices about maintenance and repair issues on my own vehicles.

I don't know anyone whose engine has failed due to lack of oil changes. But I still do oil changes on my own cars.

I don't personally know anyone who has died from dehydration. But I still drink plenty of fluids.

I don't understand your logic, as you seem to state that I should only worry about the banjo bolt if I personally know of other turbo owners who have had a failure attributed to a clogged screen. That logic doesn't work for me. If it works for you, then that's fine with me.

Again, I recommend that XT owners read Justin Stobb's page on How to Make your Subaru Turbo Last. How To Make Your Subaru Turbo Last :
 
I appreciate the info on the bolt. I just got the P0011 code, and I was lucky enough to be home when it happened. I'll be trying to find an easy way to pull this bolt and report back.

For anyone in doubt, the banjo bolt with filter for the turbo oil feed supply is threaded into the head, NOT in to the turbo. This means the oil supply passes through this banjo bolt to get from the head to lubricate your turbo.

Clogged banjo filter threaded into head = no oil getting to turbo. Good? Good.

Good luck everyone!
 
Just an update. My '09 XT did have the screen in the turbo oil feed line. I decided to remove mine tonight.

Trying to get to it looked to be a pain;however, I decided to remove the turbo, and this gave me all the access in the world.

My screen was actually spun in the bolt, so it was not facing the cutouts properly. I'm sure that was not helping my oil flow.

Here in this photo my wrench is on the bolt head, and it is resting on the uppipe studs. (This gives you an idea of where it is in relation to a previous model)

Wanted to bump this up since I am experiencing a similar issue as @timakatim.

I bought my 2010 FXT about a month ago. I asked if there were any major problems previously and if I could see a Carfax report. They said that they used AutoCheck instead of Carfax and everything looked ok, but I asked them to double check anyway. The techs said it was clean.

Fast-forward a few weeks: the car starts to feel like it's stalling a little bit, but no CEL. I chalk it up to the fact that I've been driving MTs for the past 11 years and that this is just some silly quirk with ATs - my mistake.

Anyway, fast-forward further to Sunday. Driving home from MD, the CEL and traction control light come on, and the cruise light starts flashing. So I pull over and scan the code with my AP... P0011... balls... I know exactly what this means (heard about it nonstop on NASIOC when I had my WRX). I decide it might be a good idea to pay for the Carfax report out of my own pocket. Sure enough, I see a service record showing the following only 8,000 miles ago:

Engine/powertrain computer/module replaced
Turbocharger replaced/repaired
No-start/hard start condition checked

This info was not listed on AutoCheck (warning to those who consider using it). I am taking it back to the dealer tomorrow to have them fix it under their warranty. I am going to reference the TSB when I take it in. Hopefully the screen can come out and I don't need another new turbo or motor. My guess is that the filter was clogged and caused the turbo to blow. The previous dealer replaced the turbo without addressing the actual issue (something similar happened to my friend and his LGT).

I will update after the dealer looks it over. The good news is that I will have only driven about 50 light miles after the light came on - the reset of the way home from MD, 2 miles to the train and back for work, and about 10 miles to the dealer.
 
@jpatt006 I had the same code, for passenger side. No smoke through turbo, oil consumption, or low oil. Good. All I had to do was remove the screens, replace the passenger side Oil Control Valve (decided to just to make sure it wasn't failing... call it a $100 preemptive mod if you will) , cleared the code, and all was normal for the past 3k miles.

My car would misfire at a stop, fighting to stay alive, when the check engine light came on with this CEL. As soon as I started moving forward the engine smoothed out and it felt like all was fine.


I truly enjoy this car, even with the 4EAT. As a first turbo car, It keeps me from wanting to mod it for all the power. It also keeps me from " red light racing " so to speak.

I am nervous about the fragile ringland issues that these engines have, and I am currently researching how to best mod this engine for longevity... aside from replacing the pistons.

Since it is all based on pre-detonation and knock, I am looking into AOS, colder plugs, larger tmic, EL headers to smooth flow, and a protune from EFILOGICS, since they are in my backyard. May as well find a VF52 while I'm at it. With all these mods I should have a pretty fun and hopefully fail free engine.

Got a little bit off topic, however, I enjoy my SH and I want to for a long while.
