Fin-Solo Posted April 28, 2010 Report Share Posted April 28, 2010 Alright well I know this isn't killing my car, because its been doing this for over a year, but if im driving sporty like, when it shifts from 5-6k, Especially on the freeway, it will squeak as it shifts, I'm almost certain its the valve seal, but your knowledge is better than mine. I have no reason to worry, Should I be worrying though? And is it necessary to replace the O-ring. Link to comment Share on other sites More sharing options...

Leaky valve stem seals don't make any noise, they cause smoke from the tailpipe. Also, what o-ring are you referring to? Link to comment Share on other sites More sharing options...
Fudge_Brownie Posted April 28, 2010 Report Share Posted April 28, 2010 Squeek on a hard shift? This sounds like it might be a motor mount, or maybe something in the dash? Edit: Auto cars are all known to spike boost on a shift at WOT, is it possible he is hearing a pin-hole boost leak that whistles? Link to comment Share on other sites More sharing options...
Fin-Solo Posted April 28, 2010 Author Report Share Posted April 28, 2010 Hmm I have been wrongly informed by my dad, thanks for clarification, the sound is like a Blow off, well same style, but its much more squeaky, and most definitely within the engine compartment (louder on the outside).Edit- Brownie, come to think of it, I'm going to go inspect the hose for leaks regardless, I have had boost problems before.

Fin-Solo Posted April 28, 2010 Author Report Share Posted April 28, 2010 I hope its not a slipping belt, I checked my serpentine belt today, and I hope to GOD its not my timing belt. Link to comment Share on other sites More sharing options...
Falcone Posted April 29, 2010 Report Share Posted April 29, 2010 if your timing belt slips a tooth or a few, you'll immediatly be able to tell. My bet is on your serp belt being stretched, and under full load let off's, its slipping on the crank. Link to comment Share on other sites More sharing options...

My bet is on your serp belt being stretched, and under full load let off's, its slipping on the crank. Sounds quite possible, Thanks for the info, I'm not to worried now. Though if it starts making more noise I'll change it, no big deal. Link to comment Share on other sites More sharing options...
Bah Posted April 29, 2010 Report Share Posted April 29, 2010 Mmmm bringing up the serp belt (if it is slipping), check the tensioner. Just grab it with your hand and see if its kinda lose or just moves easily...i think their lifespan on these cars is in the upper 150k miles? Wouldn't hurt to change the belt, but hopefully you know the sound of a slipping belt... Feel free to take a video and post it up, generally ends up with good results Link to comment Share on other sites More sharing options...
Falcone Posted April 29, 2010 Report Share Posted April 29, 2010 mine does it with a brand new belt every once in a while (since the compressor delete), but I don't care as all it spins is my ps and alt. How old is your serp belt? Could also be your compressor temporarily seizing, or your power steering pump groaning, but i'd bet on your serp belt.

Fin-Solo Posted April 29, 2010 Author Report Share Posted April 29, 2010 Couldn't be my power steering pump, as it groans from now and then, and thats a different ugly sound. Car has 101k miles, and has been maintained. so tensioner has a lot of life left? Link to comment Share on other sites More sharing options...
Fin-Solo Posted April 29, 2010 Author Report Share Posted April 29, 2010 Sorry for double post, if this doubles. I am charging my camera's battery, I'll get a video later tonight after I get gas. This means T-5 Sexayness sound time! Link to comment Share on other sites More sharing options...

jablackburn Posted April 30, 2010 Report Share Posted April 30, 2010 I just heard a "pff" noise. Sounds like the CBV letting loose the overboost on a hard shift to me. God I love the way these cars get out on the highway. :) Link to comment Share on other sites More sharing options...
Fin-Solo Posted April 30, 2010 Author Report Share Posted April 30, 2010 Yeah its super hard to hear, but its there. A lot louder in person though. Link to comment Share on other sites More sharing options...
