Forgot to add, I figured it all out.

In order to do this you are gonna need the following tools...(at least this worked for me)..

17 mm Socket (deep socket preferred)
12 inch socket extender
Socket Wrench
17mm wrench
Can of spray lube

Taking a look at your turbo from the top you see two bolts down by a hose that connects by pinch clamp there is a support for the up-pipe that connects to the block spray those bolts with pentrating lube as mine were a major PITA to remove.

Remove those two bolts and remove the brace between up-pipe and block.

Next position the 17mm wrench onto the banjo and break it free, because of the awkward angles and limited space I recommend unscrewing the Banjo by hand, after doing that remove the filter obviously.

Then just reinstall in reverse order, banjo back in car, brace, bolts done.

I'll try to get a good picture tomorrow and circle everything up.

Hope that helps some of you guys out.

Did you drain the oil to do it?

I had already done a oil change, and hadn't started the car since I filled it. I think you would lose some oil but not a lot.

I do not think you need to change the oil to do this.

Would make it easier, and a oil change is never a bad thing. But I doubt it being needed.

Unfortunately I removed all three at once so I wont be able to note anything about engine smoothness being increased due to this modification.

Thought I would write a follow up.

It’s been a few days since those changes I preformed in regards the the removal of those three small filters.

When I was looking at the filters I didn't think they would make any noticeable difference and was pretty much doing it for piece of mind and because Subaru said so.

Let me be the first to say the difference in idle and smooth power is IMHO dramatically different.

The car doesn’t "FLY" to redline, nor do I think I’ve gained any power. What I have noticed is my idle is much more stable and the engine seems smoother over the entire power band when it comes to delivery of power and throttle response.

Id go as far to say its one of my favorite "repairs\modifications" I’ve made so far. The car seems more luxurious in the fact my idle doesn’t stumble and the cabin doesn’t shake every so often from a stumble.

This is definitely worth the 10 minutes to do it. Anyone in the Maic that lives close I’d be glad to help out just PM me.

Do 06's have the AVCS and turbo line filters, or just the turbo line filter?

Thanks.

Yeah, curious too. I have an 07sti. I called my dealer and they said... bah dont worry about it, they have only had one failed turbo into their shop in 3 years because of it. I replied I probably would go to a tuner and get a bigger turbo if I hade a turbo failure. He laughed and said so would he.

I started on my '02, based on the info from FP page "all turbos", for the turbo line feed oil filter.
I'm halfway in, currently. You need a shorty boxed 17 milimeter wrench to get the banjo bolt out.
As said before, lettle oil comes out. You have to get the coolant hose disconnected and out of the way. only few drips of coolant come out.
Nope, my car didn't have the filter. I'm the second owner, since 2003 of this 2002 car sold in 2001. I bought the car stock, with not much warranty work done. I'm not sure if the shops knew to take the filter out back in 2001-2002.
Now back to the fun of getting the 4 copper crush-washers to not leak.
I'm also considering if I have to bleed the coolant system.
I tried everything, so as to make sure the filter is not inside the head.
To do that, i took the line with the 2 banjos completely out, to get a better reach into the head. Obviously, there's no way to actually see in there, unless.... hm.. maybe if I sanp a photo with a flash, if my cam fits in there...
Let me try that..

Is rough idle defined as choppy or a possible surge? My MY04 Sti has had a light idle surge for quite awhile now, it comes and goes, and I cant find the cause... It jumps between 750-900 rpms.. Its not bad enough to be a vacuum leak...

So the AVCS Union Screw Filter does not apply to the 2.0l motors, correct?

As for the Turbo Oil Supply Mesh Screen: The TSB (02-103-07) says "All Turbo Equipped Vehicles", but the FP article says only 2.5l motors. Vlad's '02 didn't have one, but it could have been removed previous to him checking.

So what's the word? Does anyone know for sure whether or not the 2.0l motors have the Turbo Oil Supply Mesh Screen?

Holy Thread Jack BATMAN!!!

I was reading this entire thread with great interest until I got to this point.
Seriously... pls go start your own thread.

I'm surprised a mod didn't already step in and ask you too.
