Default Oil Feed Line Wont Connect

Hey everyone,

I recently bought a Avo450 off a member on here. I have an 08 wrx but the turbo i bought was for the sti, no biggie, i took care of it. Well when the turbo came in everything was easy install except the oil feed line which connects to the top of the turbo and then of course where the oil is feed from my wrx. The oil feed line connects to my turbo perfect (steel braided line), but for some reason i can not thread it on to the OEM feeder.
I kept messing with it and decided to see if the one off the vf52 would work. The one thats alluminum piping. Well of course it threaded onto the OEM feed part just fine but the banjo bolt is too small for the turbo?!

So i was wondering does any one know where i can purchase a oil feed line that would connect to my turbo (banjo side) and then also thread onto my OEM feeder side.

The Avo450 btw is a direct bolt-on for the wrx (except for sti style which i fixed with proper upgraded hose) and it is also a ball bearing turbo if that makes any difference.

If anyone has had this problem and knows a quick fix please chime in
thanks guys

Maybe try contacting avo for the correct oil line adapter. You are missing the adapter the goes on your hard line to the braided line

Are we talking about the threading of the bolt or how it fits on the banjo? These things do come in different sizes. As well the orifice hole size will vary depending on the turbo and AVO should have a specific size for that turbo. For the most part the size isn't all over the place, more so ball bearing type turbos get a small hole and journal bearing turbos get a bigger hole, but this isn't 100% the case, and at the end of the day you should use the size AVO wants you to use for the turbo and that should come with the turbo and be sold with the turbo when sold used to another person. The original owner should not have kept it if that's what he did. Whatever he replaced it with should have had its own bolt specific to that new turbo he got.

We also making the assumption that the threading is standard. This turbo could have had a stripped oil feed hole that was rethreaded or it was designed for a different type of connection (not all use banjo bolts). I would talk to the previous owner to get clarification on what he used on the thing so you can use the same thing. This may mean your stock oil feed line may not work...depending on what he used and what the turbo's setup for.

Oh and pics usually help too when trying to explain these things.

ya my bad Back Road Runner. But just to clarrify he did sell me the oil feed line that came with the turbo. He said he had it on a 2013 wrx. Itsjust when i installed the turbo with the feed line already connected into the turbo and i go to try to connect it to the hard line it wont thread on there for some reason. And both threads seem to be in perfect condition. Is there an adapter out there that i could run to make this work?

Wait, you're trying to connect the braided line to the hard line? That's your problem. IIRC, the 07+'s turbo oil feed line is shared with the Passenger Side AVCS oil feed line. To use an aftermarket flexible line for the turbo, you need to replace the whole oil feed system as a whole with one of these.



As you can see, in the picture below, the hard line that goes to both the turbo and the AVCS solenoid is connected to the oil feed outlet on the head itself which is where your braided line needs to connect.



Both the turbo and AVCS solenoid need oil and I don't know of any pre-built oil line that bolts onto the turbo oil feed extension tip :-(. You don't want that hard line anyway, it's prone to cracking which causes bad things like engine fires, turbo AND engine failures. It's not as nasty of a job as it looks to remove. You don't really need to remove the intake, just cut the AVCS extension off from the turbo part so you can pull the line out from the front. Don't dremel it to cut it though, use bolt cutters or something to avoid metal flake getting into the heads.

The real PITA is installing the new one, no one makes it quite long enough

This thread will help, it tells you everything you need to know. http://www.iwsti.com/forums/2-5-lite...placement.html
