ALL, I have a WRX and normally wouldn't say anything here in an STi thread, but the WRX turbo is cooled by coolant, not oil. I am surprised to hear WRX owners having this problem. And as many times as I have had the uppipe and downpipe off my car, I don't know of any oil lines in that area. That picture would help!

Thanks, I will have to look for that hose the next time I have the exhaust off the car. This opens a new door, is coking a problem?? I never invested in a turbo timer because of my misnotion of no oil being used. Point me in the right direction. Thanks again for the education.

Turbo timers are a fairly popular add-on. I don't plan on getting one but my drive home for the last two hundred yards is less than 10 mph. I also use a synthetic oil which is supposedly less prone to coking in the turbo. The water-cooled center bearing was used on the stock turbo to alleviate the problems of coking. It works as long as you keep the coolant level at the proper level (little or no air in the system and the reservoir bottle at the proper level).
I don't think it hurts to have a turbo timer. I would consider it to be insurance. If you have the factory alarm, you will have to look at ScoobyMods.com for a wiring fix.

oil return line
Question, Is this happening to every 2004 STi or is it just a few here and there, its starting to worry me. Also sorry to those who have had it happened to them sounds like it makes for a nasty fix and clean up.

This rubber line in question is the ontly thing that makes it a pain change out a turbo. There was a clamp on the one I worked on. I don't know why people quote 4+ hours. A turbo change is a 2hr job max...it does help to have a FMIC since reinstalling a TMIC is a PITA.
The biggest probem getting a turbo on the car is trying to get the turbo's oil return spout into the rubber return line. The clamp hinders you because you have to leave it in the correct position and try to cram the turbo in. Due to total lack of room with the intake manifold in place, there is no way to put the clamp on after the fact....or is there?
1) Before putting the turbo on. Open the clamp and use a ziptie to hold it open. Leave at least a couple inches of excess on the ziptie.
2) Place the clamp on the hose with the ziptied end facing the front of the car.
3) Smear a little oilt onthe entrance of the hose and on the spout of the tubro, then put the turbo on. The may require some finess, but it will be a lot easier since the clamp is a non-issue.
4) Using one of those 3 fingered flexible shaft thingies, used to grab small items out of tight places, grab the clamp and put it into position. It shouldn't be so loose that it will fall once you let go.
5) Use a very hobby knife (X-acto) to cut the ziptie to close the clamp. You could also burn thru the ziptie. Remove the ziptie with the previously mentioned tool.

what about replacing the rubber hose with a stainless steel hose. I mean if one is replacing the turbo might as well replace that hose. If the stainless hose is a bit longer it would reach very nicelly clump in and never have to worry.

Thread from the dead!
I've been having this issue with my 2004 STi engine (in a 2000 2.5RS), and I'm curious to know if anyone went with a slightly-too-long hose instead of the stock one to try and prevent it from coming loose or popping off?
Does anyone know the specs of the hose so I can pickup a replacement without having to trek over to the subaru dealer?
