jazzymt Posted May 1, 2006 Share Posted May 1, 2006 So, I finally went stage 2 this weekend. All issues aside (stuff I will cover in another thread) - I hear a very quiet whistle upon heavy acceleration. I'm thinking (hoping) it could be a heatshield ringing...I dunno. I used copper crucial gaskets on the manifold, uppipe & downpipe along with permatex copper gasket stuff. Manifolds are torqued to spec, uppipe & downpipe are torqued...well...a lot. Lock washers & anti-sieze are on all the bolts. So, ah...you think a quiet whistle/ringing is a leak? Or would it be fairly loud & noticable? Or, do the copper gaskets never leak - the just drop bolts?

specinvstr Posted May 1, 2006 Share Posted May 1, 2006 +1 it scared me a bit at first -- but it is the turbo you're hearing.. +2. I went stg2 this weekend and I have been hearing the same sound. Link to comment Share on other sites More sharing options...
twowheels00 Posted May 1, 2006 Share Posted May 1, 2006 I also finally got to Stage 2 this weekend. PUMPED!! I checked, double-checked, and triple-checked bolt torques. There's more noise, but nothing I would say is an exhaust leak. I can hear the turbo spooling, and even the BOV in short, slow, accel's. Crucial pipes and gaskets also. I'll be checking the torque again tonight since I'll have put it throught about 5 heat cycles. Even more successful, the only thing I lost was one of those plastic fasteners on the engine cover!! Different path, but one wierd thing that happened..... When I lifted the engine to get the uppipe out and then set the engine down, the engine shifted!! The mounting bolt wasn't even near its hole. At first I was quite concerned, but then I put the manifolds back on and just moved the engine back into place.... phew. Link to comment Share on other sites More sharing options...
jazzymt Posted May 1, 2006 Author Share Posted May 1, 2006 Thx guys. Exhaust leaks are like the bane of stg2'ers existence. I got enuf on my plate I don't want to have to worry about leaks right now - especially after doing that whole install by myself. Now I can concentrate on getting the 02 sensor that I totally ruined fixed. Gratz on other recent stage 2'ers too! Doing both UP & DP is quite the task!

specinvstr Posted May 1, 2006 Share Posted May 1, 2006 lol I also went the crucial route this weekend. I was getting tired watching whitetiger install everything. He butchered the up egt so we did not have to lift the engine. Giddy up. Link to comment Share on other sites More sharing options...
crash Posted May 1, 2006 Share Posted May 1, 2006 Damn, I guess it was up pipe and down pipe weekend huh? I installed my Borla Uppipe and Flow downpipe. My OE gaskets for the downpipe did not come in last week as I had hoped so when I put those on, I'll re-torque the up pipe... No AP for me yet, but the butt dyno likes the results (and the studder has decreased significantly!) Link to comment Share on other sites More sharing options...

There's no need to lift the engine at all, the UP will slide out of the bottom with everything else in place, as long as you remove the EGT sensor.

FWIW, I unbolted the engine and tried to lift it, but it wouldn't budge...I got it maybe 1/2" up, but after taking out the EGT & the HS bracket, it came right thru.

twowheels00 Posted May 1, 2006 Share Posted May 1, 2006 I couldn't get the EGT sensor out, actually began to strip the nut, so I just lifted the engine. No big deal either way. Link to comment Share on other sites More sharing options...

jazzymt Posted May 1, 2006 Author Share Posted May 1, 2006 I couldn't get the EGT sensor out, actually began to strip the nut, so I just lifted the engine. No big deal either way.Weird. My EGT came right out, no prob. The F'in O2 sensor is another story. I'm gunna kill the engineer that located it right next to the uppipe bolt...can't turn the damn O2 sensor socket because it hits the bolt. Next, I'm gunna kill the subaru tech that put in the new O2 sensor w/o antisieze. 7/8" open ended wrench rounded the crap out of the flats on the sensor. Finally sheared the end of the UP bolt threads off with the O2 sensor socket & an 18" breaker bar. Took me like 2 hrs to get it out including riding my bike to NAPA to pick up the O2 sensor tool. Then I got PB blaster & antisieze on the sensor - didn't take long for that CEL to come on...I'm sure it's ruined. Oh well, the dealership owes me a favor - they can replace it... again.

ProConcept Posted May 2, 2006 Share Posted May 2, 2006 I have a odd ringing too. It only happens upon heavy acceleration between 2k -3k. Crucial up, COBB dp, crucial copper gaskets. Link to comment Share on other sites More sharing options...

Crucial up, COBB dp, crucial copper gaskets.Yea, I don't think it's the turbo - I think it's the turbo heatshield rattling because the 7 bolts have been reduced to 3 & it resonates at about that RPM under heavy load...probably a little bit of both really.

STIMD Posted June 19, 2007 Share Posted June 19, 2007 I got a noise that I could describe as a low pitched whine as well. Strangely, it happens on any degree of acceleration and when the clutch is disengaged and I'm coasting. The noise will go away when the clutch is only partially engaged or under engine braking. And this is all new since the uppipe went in. What the hell is it? Link to comment Share on other sites More sharing options...

What the hell is it? ive got the the same problem except i have a 5EAT. but i hear it anytime my foot is on the gas, but not so much when im coasting. and when i break or let off the gas, i dont hear it. what should we be hearing/not hearing?

Why does everyone take the front O2 sensor out? If you just disconnect it from the wiring harness and pull the two push pops off the block bracket and pull the chord down; you can get the heatshield off and use a boxend wrench on the UP bolts. I'm posting a spin up video on youtube right now. Here's the link: [ame=http://youtube.com/watch?v=uGdh55cFU1k]YouTube - Stage 2 Whine And Hiss 05 LEgacy GT[/ame] The hissing is right at the beginning of the video so turn up the volume and restart it.

STIMD Posted June 28, 2007 Share Posted June 28, 2007 Turns out it wasn't exhaust issue at all. The rear diff is being replaced under warranty at the dealership. Link to comment Share on other sites More sharing options...
