Dispatch20 Posted November 25, 2015 Share Posted November 25, 2015 yep! thats the noise. when you bend down into the engine that same taktaktak noise is what im hearing. is that normal or should i be concerned? ive never driven an ej25 before this one so i dont know what the proper sounds are My previous LGT made that same noise and it ran really healthy. I think all of my 5 of my Subaru's sounded that way to varying degrees. Link to comment Share on other sites More sharing options...

asegal17 Posted December 7, 2015 Author Share Posted December 7, 2015 So the engine is still running fine. But I've developed what I think is a power steering issue. If it's a particularly cold morning or if the car is in full lock under load it makes a high pitched squeaking. Now this doesn't appear to be an especially catastrophic issue but i thought I'd post it here instead of starting a whole new thread Any input?

Moderators BarManBean Posted December 7, 2015 Moderators Share Posted December 7, 2015 Check power steering fluid level, belt tightness, and also for evidence of a leak on top of the pump. Many have issues with an oring in the line that enters the top of the pump. I actually picked up 2 orings just today to fix this issue on my own car.

Max Capacity Posted December 8, 2015 Share Posted December 8, 2015 On full lock, cold that is not that abnormal. Stop doing that. Like BMB said, check the belt, make sure it tight with a little play, check it for age cracks too. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs.

xt2005bonbon Posted December 8, 2015 Share Posted December 8, 2015 Actually, I recall reading somewhere that we should always avoid full lock. Link to comment Share on other sites More sharing options...
asegal17 Posted December 9, 2015 Author Share Posted December 9, 2015 Actually, I recall reading somewhere that we should always avoid full lock. I'll make sure to avoid that now, as I have been going on full lock every morning as I back out of my driveway Link to comment Share on other sites More sharing options...
Scruit Posted December 9, 2015 Share Posted December 9, 2015 If you hit full lock then fine. Don't hold it there, though. Does it sound like belt squeal? Link to comment Share on other sites More sharing options...

sbw Posted December 10, 2015 Share Posted December 10, 2015 I've had a wristpin actually break in a set of aftermarket CP pistons before. There is no way you could miss the sound. It sounds like a completely toasted bearing/tapping. That recording didn't have that sound. Link to comment Share on other sites More sharing options...

asegal17 Posted February 4, 2016 Author Share Posted February 4, 2016 How is the belt tension? Sorry I forgot to update this. The guys at AZP found that the belt size itself was incorrect for my car (previous owner must've put the wrong one on) and fixed it for me for $30 in about 10 minutes. Again, they're the best Link to comment Share on other sites More sharing options...

asegal17 Posted March 7, 2016 Author Share Posted March 7, 2016 Brought my car in to AZP on Saturday for a compression and leakdown test. If that checks out, then I'll be lowering the car on H&R Sports Link to comment Share on other sites More sharing options...
asegal17 Posted March 9, 2016 Author Share Posted March 9, 2016 Got my compression/leakdown test back. Cyl1: 151psi - 3%leak Cyl2: 157psi - 0% leak Cyl3: 147psi - 5% leak Cyl4: 141psi - 5%leak The goal was appx 150 psi Other notes: They do suspect a minor bearing issue. The oil analysis I'm doing will tell if there is any bearing or knocking evident in the oil. Link to comment Share on other sites More sharing options...
xt2005bonbon Posted March 9, 2016 Share Posted March 9, 2016 I think those results look fine. Link to comment Share on other sites More sharing options...
asegal17 Posted March 10, 2016 Author Share Posted March 10, 2016 i agree xt2005. the Oil analysis will tell us more though. the suspicion of the bearing comes from this noise ( ). the noise is that low tiktiktiktik. when i looked at the oil that had been there for 3k i found no sparkles in it--another good sign. however this noise is still making various mechanics, dealers, and subie guru's nervous.... to varying degrees.

Scruit Posted March 10, 2016 Share Posted March 10, 2016 This is what mine sounded like: Never did find the cause - except the #4 cylinder had a badly broken ringland. The wristpins and rod bearings were all tight, no discernible play. Link to comment Share on other sites More sharing options...

Yeah I can hear it. It has the tick of a quiet diesel engine. Do you have another video of it when you rev it a bit, and keep it steady at a given rev?

xt2005bonbon Posted March 10, 2016 Share Posted March 10, 2016 I can hear it there as well. mmmh, I am not sure. Do you have the btssm app? Or a way to log and see if the knock sensor gets triggered with this sound? Just wondering.. I can't remember, you've inspected your timing belt tensioner right? also the small idler pulley next to the timing belt tensioner is new? old? I would also perhaps try to disconnect if possible all accessories to rule them out (e.g. ac compressor, power steering, alternator). That's a tough one man. In any case, the oil analysis will be very helpful to rule things out. Link to comment Share on other sites More sharing options...
