Exclamation IMPORTANT:filters in banjo bolts

This is not in reference to the rough idle tsb concerning the avcs inlet banjo bolt, but instead where this oil feed line connects at the heads.

This is a long post from the lgt forum, it starts as just another oil thread until post #123, where a Subaru tech posts his findings. Things get VERY interesting from there. Read this and tell me we shouldn't be worried.

That was an interesting read. Are people removing the screens or cleaning them or replacing them?

Don't know, but it's got me worried. My vote is file 13. I've never liked extended oil changes, but on the last two I've went 5300 and 6000 miles on Mobile1, still under the recommended 7500. Now they say all turbo 2.5's are to be considered driven under, "extreme conditions", and oil changes are now recommended at 3750, that's a big step from 7500.

Have you seen these mentioned banjos? The timing gear has to be removed to get to the driver's side banjo, just maybe one small support from the turbo up-pipe to the turbo may have to be removed for access to the passenger's side. It would still be tight, but with patience and tiny hands it might be doable. It doesn't look easy for the average driveway mechanic, does anyone know what the dealer would charge to change them out?

umm.. that forum looks like it's down now, but I think this might have been discussed somewhere here or on iwsti. If it is, then i've done it before and it is easy. Both sides are fairly easily accessible, and can be done in you're driveway.

Since I can't see the reference thread by OP, I really can't say for sure it's the same.

edit: this is the TSB i am talking about:

I wish it were those banjo bolts, like you said, easy fix. After reading that entire thread more than once, it looks as if that particular filter has been removed and the filter now resides in the other banjo bolt that supplies oil from the head. Follow the oil line from that same bolt you removed to where it enters the head, dat's da one! Don't know if they started with filters in both ends of the feed lines, (total of four), and reduced it to two, or if they just decided to move it to the other banjo. Subaru made a running change at the factory early 05', what they did, who knows? This would affect models after the change, so 2.5 turbos sometime in 05' and up.

Just checked, couldn't access the thread either.

My attention span started to drift once the back-and-forth started...

But what I gather is this:
-in addition to the screens from 04STI's that were no longer installed in later years, there are two more screens that need to be replaced every 30,000 miles

Is that correct?

From an '04 service manual

There are four T6 banjos. I have replaced the T6 colored green in the image.
The other two T6 banjos (colored red) are the suspect of engine failure according to the thread from the OP.

In MY04 STI the Top banjos did have screens that were already unattached from the banjo bolt.

I'm going to check the ones you have highlighted in green just to be sure. Oh, should be five banjo's, three on the passenger side, one on the turbo, oil feed from the head, oil feed inlet for avcs.
