05 Legacy GT P0011 Code help

Hi Everyone.

I have an 05 LegacyGT Wagon 94K miles standard

No problems with the car...doesn't lose power..performance just fine

It has thrown a P0011 code..

 

I gather that the Banjo filter might be clogged...and just want to make sure that I am about to go after the right bolt that serves oil to the Turbo.

Can you tell me if I have located the correct bolt and if there is only one??

I think its the one top of the Turbo as indicated in my first picture..

Is this the ONLY one that needs to be checked?

Do I just buy new washers and replace the filter for service??

Seems to me the other two banjo bolts that I have located are on the coolant side...

 

So the only Banjo Bolt that services the oil to the Turbo is the one that I have marked in my first pictures?

 

Is this the most common issue with the P11? These have never been serviced

Thanks for any help!

The one you're really looking for is on the back of the passenger side head -- basicially behind and below where your pictures are indicating. Follow the oil line to the back of the head, you'll see another banjo bolt with a bump on it, which means it's got a filter inside. Remove bolt, stop oil flow as much as you can, and use a pick to pull the filter out.

 

Ideally, you should do this as a side-step to an oil change, since, changing the oil wil also help.

 

Sadly, this will likely be the start of your issues with the LGT. Your turbo is on its way out, replacement is the best course of action here.

 

Obligatory #ynansb.

Don't drive it. My turbo went within about 50 miles of the code.

Yeah do not drive it at all. I blew my turbo as well lol

Thanks Guys

So..what needs to be done?? Replace the oil line feed to the turbo along with the filter??

Am I just guessing??

I am really looking to sell this car....it has 93K on it..

What is the general lifetime of a turbo in these cars???

I might end up selling this car to a coworked and don't want to sell them a bum steer as well.

So I am wondering if I should get the turbo "just in case" before it blows, if it ever does..

If it does blow would it damage other things?

Thanks!

If it blows, it'll absolutely damage other things. DO NOT sell this car to anyone you will see again.

 

Replacing the oil line doesn't do anything for you, unless it's obviously damaged, which, if you didn't mention it before, would be the cause of your issues. However, if that particular line was somehow crushed or bent, it would be secondary to some other, equally serious damages, like crushed fenders or hoods.

 

If you must take it off, shoot it with some Brakekleen until it runs clear, that's about all that needs to be done.

 

Your turbo NEEDS REPLACING. NOW.

 

Once you do that, you should be OK for a few more thousand miles.

 

Send a PM to JmP6889928 and ask about his replacement VF40 turbos. I'm personally running one of his, as well as many others, and he does great work at a very competitive price, plus, is an all-around great guy. Support a fellow forum member and get yourself a great replacement turbo in the process!

Turbo may be fine, unless there is excessive shaft play. Pull the OCV's and clean them up real good. Remove the banjo bolt filters, fresh oil, your car will be fine. Or to be safe spend the $90/ea for new OCV's, which I personally recommend regardless with the miles on the car.

Thanks everyone for the replies.

I have only driven the car about 20 miles since the P11 CEL light came on..

So I am curious..what else happens when the turbo lets loose?

I have called a couple garages...and they tell me that all kinds of things could be wrong with the engine...which I find really hard to believe...My rods could be going..my cam is shot and etc and etc..sounds like a whole rebuild .

I change the oil in this care every 3000K it has 93K on it.. I can't remember the CEL light ever coming on...and about 6k ago I had the timing belt and water pump replaced...

So I plan to tow it to a garage that has serviced me well in the past and see what they say..

Anyone want to offer some guesses???

This is an 2005 Legacy GT Wagon with the 2.5L Turbo...are these engines prone to all kinds of problems all of a sudden??

Thanks!

If they don't specialize in turbo Subarus, you will be doing more harm than good. Take it to a specialist, or don't take it at all, it'll just be money wasted.

If you do not turn wrenches yourself, expect it to get real expensive real fast. As was said, if they don't specialize in Subarus you're just wasting your money. If you've read the posts, we've offered guesses, likely accurate as we've all experienced the P0011 code. Takes 20 minutes to pull the OCV's, clean them and reinstall them. Banjo bolt filter is slightly trickier, but doable.

Where are these OCVs that you are recommending me to check out?

I couldn't service the banjo bolt....as one of the blocking brackets..had a bolt that I just couldn't loosen even with a 14" breaker bar...

I am pretty decent shade tree car guy..so if servicing the OCVs is reasonably easy I might go after them...just not sure where they are..

thanks!

soak the bolts in pb blaster and let it sit overnight and try again. Getting that filter out is very important.

 

OCV's are pretty easy. One on each side of the engine. If you look at where the injectors are on each side, you'll see a plug that goes into a sensor. That's the OCV. Unplug the sensor, undo one 10mm bolt and they should slide out. Driver side is easy, passenger side might fight you but it will come out eventually. A quick google search will reveal more info

Service manual. Make sure your in the right section for GT's (DOHC) 2005's start around page 1600, in the back of the book is a section that show's how thing work.

 

If your a decent shade tree ... you can do most the work, fixes yourself.

 

All the info is how. See my click here link for some pictures.

 

I have both banjo filters removed.

just for more back ground.

2dan,

That code is an indicator that there is not enough oil pressure getting to the ocv valves that control the camshaft advance. That same oil line also provides oil to lubricate the turbo. This means your turbo has already been starved of oil. It is imperative that you not run the engine until you remove the banjo bolt and check the filter. If the filter is clogged, remove it and replace the turbo. Otherwise you will have to get familiar with Mr. Tris's or Max Capacity's engine rebuild threads...

 

If the filter is clear then you likely just need to clean or replace the ocv valve.

 

You say you change your oil every 3000miles. Have you owned the car since new and always followed the same oil change interval?

Good luck.

Also see LGT cycle of fail

Yeah.. I have owned the car since new...and have always changed the oil every 3k..

The past few years I have been using the high mileage oil and as well one quart of the lucas oil treatment...

 

Thanks!

Dan

That is odd. If you've had the car since new and have done 3000mile oil change intervals, that filter shouldn't be clogged.

No really, At 141,000 miles I got the P0011 and P0021 CEL. My story is on here, did all the oil changes, 3500 to 5000 or so depending on outside air temp.

 

The vf40 is a POS. those banjo filters don't help.

Max,

Was the filter clogged when u got the codes?

Hi everyone

I broke down and took the car to my local Subaru dealer...who determined that the OCVs are the culprit (gunked up) and there are fluctuations of Oil Pressure/delivery to the cam shaft..

They recommended a power cleaning/flush of the Oil system in the car.

They told me that this works most of the time. Sometimes, though the cars come back with still problematic OCVs.

 

to Note..

93K on the turbo car..changed the engine oil every 3k myself...

So pretty diligent on the oil change.

Since 75K been using High Mileage oil..Never seen synthetic

Max,

Lets see it's been how many years...oh wait, I still have the filter here in my desk. I'd guess may be 60% clogged.

 

It's hard to look down the inside even with a Mag-Lite. But when I shine it from one side to the other you can see lots of places the light doesn't shine through.
