Exclamation 04 STI motor failure root located

Well, I went by the dealership that I traded the old STI in to and bought my new one. THey had torn the motor apart and found the cause of the failure and you'll never believe this... The oil pickup tube broke between the tube and the flange that bolts to the block. The break obviously caused a loss of oil pressure resulting in multiple bearing failures throughout the block. The tech said he spoke w/ Subaru and they changed their story/reason for denying the warrenty claim to "that part just doesn't break." BTW I did take a few pics w/ my cell phone and I'll upload them later tonight. In all my years never seen one fail right there without some obvious cause... all I can guess was a bad batch of metal...

There was another STi driver on this forum who had the SAME problem. His was covered under warranty. I will look for the thread.

I believe this is the same part. Take a look at the photo on page 2. If I were you I'd be asking for money back, because you should have had your claim covered on the old car, and thus had a much higher trade-in price.

Yup, mine looks exactly like that. Photo on my cell phone looks like crap and all blurry, can't see much. I'll still try and upload it later if I can.

Moomba, did yours get covered under warranty? I wonder why these parts would break, I can't imagine there's a lot of stress on them.

I would expect that there is no reason, even with mods, to deny a claim for a broken oil pickup tube. Obsidian's dealer saying the claim was denied because "these parts just don't break" is ridiculous. Apparently they do break, because there's a broken one sitting in your shop you idiots

They said almost the same thing to me about mine actually. I dunno yet if they will cover it or not. I'm still waiting on an answer. Supposedly, the head guy at Subaru is gone for the holiday and won't be back until sometime next week. So looks like a bit longer in the dark.

What I do find VERY interesting is that all of these seem to be on '04's and all seem to be breaking around the same time. The one in the other thread was just a few months ago as well... very odd indeed. Definately seems indicative of a weak batch though. My friend is a mechanical engineer and used to work for GM a few years ago took one look at the photos of mine and other's issues and on first glance agrees (although he would like to inspect the actual parts more closely before making a definitive judgment.)

They were trying to claim that it was because of any mods or how I drove the car, but even IF I had mods (of which I ONLY had sways on the car) it should not and would not cause this part to fail like it did. The car was my daily driver. I have a track car specifically for track days and SCCA racing. Some things I could see how they could deny, but something like this that sees no real direct stress simply should not fail unless there was a manufacturing defect (or if someone disassembled the motor and perhaps tweeked it causing a hairline fracture that got worse over time, but the motor had never been opened (although another local dealership had pulled the motor about 1.5years ago but to the best of my knowledge they didn't open the motor simply remove to gain access.))

I'll post again and let anyone know what happens with this, but at least the managment at the dealership is very sympathetic and is actually working to get it covered (even though I've already bought a new STI myself.)

+1 for Bunky Gandy in Huntersville, NC (They've been a real help through this.)

Oh and for the record regular oil changes were completed every 3k miles (no more than 3500mi between), always used Subaru oil filters. The motor always seemed a bit rough but I didnt' think much of it as it IS an STI and there are a lot of vibrations, but my new 06 is much more smooth than the 04 ever was.

I also regularly checked the oil level. I actually had been doing this more often lately as I had been noticing a bit more oil being consumed by the motor than before, but I just made sure it was topped of and it seemed happy enough.

Just before it happened I noticed the oil light came on when I pulled into a local BestBuy. I checked the oil level and it was a bit low so I topped it off started it again and it went off. I drove maybe 2mi down the highway and the motor seized when I downshifted getting off the off-ramp.

I don't know the guy, but up here in Canada (Winnipeg) an STI owner had the exact same thing happen last year. It was covered under warranty, but SOC wanted the motor sent to them for inspection, because they did not believe it.

At least that is what the dealership told me a few months ago.

That is common practice with most system critical components. Typically they will undergo metalurgical analysis to try and determine what caused these parts to fail to begin with so they can ensure it does not happen again. If the results are severe enough then it is possiable it could lead to a full fledged recall which Subaru wants to avoid at all costs.

That looks like impact or vibration damage. If there was a problem with the part, it would generally break at the weld not on the metal pipe itself...

Well if you look at it a large portion did break at the weld at the flange and it goes up some from that. I'd surmise there may have been a small crack or seem at the wled and then with time progressed around the circumfrence. However, instead of the crack being caused by the actual welding itself I'd guess it was some inherant weakness in the metal of the batch and so the crack followed the weakness around untill it totally broke.

In Moombas pic it looks like it began to break down around the weld then over time got worse spiraling somewhat upwards untill it actually totally snapped which would explain the sharp/steep edge to it.

Hmmm.. interesting... mine was May 2003 as well. It was in the 2nd or 3rd allotment of the initial run of STI's. Very interesting...

In this case, perhaps a upgradable part should be mass produced.

If someone said "Hey i'll sell you this upgraded oil line for 15 dollars" I would buy one at this point so that **** didn't happen to me.

You can buy a new oil pickup tube from Subaru for like $20 or so. It's not an issue of getting a replacement as much as the removal and instillation of the new one. In order to remove/install it you have to pull the motor to be able to remove the oil pan. While Subaru's are relatively easy to remove a motor it still will take the better part of a weekend to remove, replace the part, and reinstall the motor for someone who is fairly experienced in pulling motors. I believe last time I pulled a Subaru motor on a friend's WRX took about 6 hours to get it fully disconnected and out of the chassis. If it was a simple replacement that'd be one thing but unfortunately it's not.

Really? On almost every car I've seen you can't pull the oilpan typically because you run into interferance issues with the subframe. If you can access it without pulling the motor then yes, it would be possiable to replace it with relative ease. I'll have to put mine up on ramps and take another look at the clerances.

You can lift the motor without removing it you know. Thats what you have to do for installing engine mounts.

But for reference, the technicians at the scoob dealer I work at dont need to remove the motor for oilpan replacements.

The actual build date should be on your driver's side door panel, but either way it definately sounds like it was probably built around the same time as at least two others with this issue.
