Were you guys stock when it happened?

I have an intake tube (Perrin) and Catback exhaust. That's pretty much it, besides suspension. My dealer is charging me $110, after they claim it's just my intake. They're denying that there is even a DI issue. So, I'm currently fighting them on this.

Question

Will replacing the seal fix this problem?

It's my understanding, that you need the seals/collars fixed...then update the ECU with a supposed fix to prevent it from happening again. I believe it retards the timing over 5200rpm when accelerating.

What do u mean by collars.

I know there is an insulator and the actual seal

No.

It retards spark over 5200rpm WHEN THE CLUTCH IS DEPRESSED.

Fair enough. I was going off the TSB posted, which states during acceleration. Where does it officially state this? Not doubting you, just trying to stay informed over the ordeal I'm in right now with my dealer. Thanks!

How much does it cost to buy a set of direct injectors? Are they readily available?

Hello everyone,

Got my car back today (dropped off Tuesday) after it exhibited symptoms indicating failure of Cyl #1 DI seal. Sure enough, that's what the issue was. Toyota flashed ECU and replaced seals, which got rid of the firecrackers under my hood. As I was driving away, I got a CEL and proceeded to pull over and dump the codes. Disappointed to see P0351. Gonna call around tomorrow to see if I can buy an ignition coil from either Toyota or Subaru for my FRS. I have around 34000 miles on mine. Already have an email in to epifan. Gonna be sending them in a dump of my ECU so they can compare.

Here is a pic of my DIs:

What kind of driving conditions does your car see?

Streets of Willow once about 3 weeks after purchase, AutoX multiple times Mulholland a bunch, drive from LA to Tempe, Arizona twice and LA to Vegas once. The rest is a minimum of 60 miles of 'spirited' driving in commuter traffic a day.

That looks bad

Thats no where as bad as some cars have seen. I may even call yours just "more aggressive street driving"

I dont believe they are readily available since there is people waiting weeks for them to be shipped from Japan. They also seem pretty pricey.

Anything to do with power/engine is stock unless drop in air filter by HKS counts... Stock intake, stock engine (no pulleys etc.) stock headers all the way to the mufflers.


Ok update:

So apparently Subaru Corporate is aware of the issue and is working on a fix either ECU or new DI design (they have to fix it for 2014). However since there is no fix yet there is no TSB (bulletin) on it yet. They also pulled the cricket noise TSB because it temporarily fixes the issue and it comes right back. Theyre working on a solution that will fix both. Now the big problem for us is that since there is no TSB, Subaru Dealers dont know what is going on because they base everything off the TSB. So you have popping noise? Subaru Dealers check the TSB, no TSB for popping noise. Popping noise is considered "normal." Now we all know that isn't normal and they know it isnt too but the dealership can't really do anything unless your engine blows. IF your engine blows Subaru Corporate HAS to cover your engine because they are aware of the issue and dont have a fix for it yet. I find it very weird why they rather have engine's blow up and replaced rather than replacing the seals to "temporarily fix the issue." The latter seems like a cheaper alternative. Now I could pay out of pocket (150 quoted by my dealer) for a diagnostic fee. I dont know exactly what they will do but if they do find a leaking DI seal they will warranty it and refund the 150. Now the dealer can screw me over and say "oh its your drop in air filter and once we put in a stock one the popping noise stops." Then they make away with my 150 for what is essentially a BS diagnostic. It seems like if we dont want our engine to blow up or be replaced we need dealers and corporate Subaru to be aware that this issue isnt just a small population of owners. It seems as if Toyota is willing to replace the seals while Subaru isnt willing to do anything unless we pay for diagnostic or after our engine blows...

Personally I believe this issue isnt just because of tracking the car. I believe it is also heat related. The first case of this issue recognized by Corporate Subaru was in South Africa (which is generally hotter than here in the states). During that time we were facing Winter and Spring months. Now that it is Summer, this issue is all over the place now. It is appearing whether a person tracks their car or uses it as their daily driver.

With all that said I would really like Subaru to fix this issue rather than have me drive my car around until the engine blows. I really don't like the idea of having the dealer work on my car, or worse... swap out my engine.
