SamT07 Posted May 17, 2017 Share Posted May 17, 2017 So my car hit just about 120k miles. And I won't lie I push the car time to time. At 117k miles I took off my dp to check my shaft play and I had absolutely none. No side to side nor front and back. Right after I hit 120k I was on the freeway on my way to a car show and I was doing 80mph cruise control. I turned off cruise cause I was exiting and I tried to downshift (MT) and my RPMs just didn't want to climb. I very slowly drove a mile down the road to the car show and I parked. I popped the hood, oil everywhere. I had my friend get in and rev and my BOV was just spewing out oil, not even mist. Also the turbo made a click-clacking noise. I got it towed to my dads shop and threw it up on the lift and started taking everything apart. I take out the turbo and the exhaust and intake are just filled with oil. Now the exhaust turbine moved back and forth like an inch but not really side to side. The intake, shaft play for dayyyys. Side to side, up down, even the nut that holds the turbine was loose, on the last thread. So anyone know what could've happened? And how did this not get super catastrophic???

Gex Posted May 17, 2017 Share Posted May 17, 2017 You blew the oil seal and sounds like you caught it in time. Did you pull the banjo filter on the back of the head? Link to comment Share on other sites More sharing options...

SamT07 Posted May 17, 2017 Author Share Posted May 17, 2017 The banjo bolt that goes on the line that's on the block of the motor by the turbo was the only one I actually took out and replaced Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

SamT07 Posted May 18, 2017 Author Share Posted May 18, 2017 When I replaced the turbo, I changed every rubber hose that connects to the turbo. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

SamT07 Posted May 18, 2017 Author Share Posted May 18, 2017 Oh I used the one that came on the turbo already. It was attached to it so I used that. I just googled it and found out what you are talking about. Thanks. Good to know Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

SamT07 Posted May 24, 2017 Author Share Posted May 24, 2017 *knock on wood* it's been 2k Miles with a used turbo and so far so good. I kind of have a dirty air filter (will change soon), and the car kind of hiccups I guess when accelerating sometimes and I'm wondering if it's from that Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Max Capacity Posted May 24, 2017 Share Posted May 24, 2017 These cars have a stumble from 2400-2900 rpm. It's very slight but the driver can feel it.

Max Capacity Posted May 26, 2017 Share Posted May 26, 2017 Read around the threads there are way's to make it better. A tuner can fix 99.9% of it. My wagon doesn't have the issue. My 09, I have moved the vacuum hose from #4 intake runner and T'd it into the small hose off the blow off valve. Reset the ECU. That help a little. There is a thread about a longer fuel feed hose and the STi fuel regulator, or even putting a in line fuel filter in. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs.

CapnJack Posted May 26, 2017 Share Posted May 26, 2017 I'll take a stab at an idea for why it went out. I like to equate the turbo in our car to a Schrodinger's cat scenario. If you don't look in the box is the turbo 1) dead 2) alive 3) both? For example(stolen from the web and modified below): A turbo is locked up in a Subaru Legacy, along with the following device (which must be secured against direct interference by the turbo): in a banjo filter, there is a tiny bit of dirt, so small, that perhaps in the course of 117k miles it stays in the filter, but also, with equal probability, perhaps none; if it dislodges, the dirt goes into the turbo and causes catastrophic failure. If one has left this entire system to itself for 117k miles, one would say that the turbo still lives if meanwhile no dirt has dislodged. The psi-function of the entire system would express this by having in it the living and dead turbo (pardon the expression) mixed or smeared out in equal parts. The question is, did opening the turbo cause the failure or had the turbo begun to fail before opening it? One may never know... Link to comment Share on other sites More sharing options...
