hey guys. im just posting up to see if you guys can help me out with giving me and idea with what is going on with my 2008 evo x gsr. i just had a mechanic install a new clutch because my stock one finally started to slip. when i got it back the bov sounded alot louder. and people where telling me its compressor surge? or something like that... im running the stock bov . turbo back exhaust, injen intake and ic pipes, and ams manual boost controller. ams tuned . i am putting up two links to videos of my BOV, first is before clutch install, the 2nd is the day after. does it sound ok? 25 psi. please any input will help . is this normal flutter? cuz i thought is sounded ok.. but im not sure..

Yea that is not a good sound. That is some serious flutter. They only did a clutch install?

 

yeah ... only a clutch install.... so how does that make my **** surge?... unless they ****ing beat on it and ****ed something up...

 

Wow, I have no idea what could have caused that. You need to contact the people that did the install and ask them about it. Tell them what it is doing. Something is not right, and a clutch install has nothing to do with that. They must have messed with something. In the first video, it sounds like you are recirculating, but in the second it sounds like it is VTA. Check to make sure your factory DV is still plugged in to recirculate.

 

hmmm weird as this happened to you with only a clutch install. Mine only gets that sound if I'm not boosting long enough with higher gear and even then, it's only a quick burp. Normal use it will sound like the first video. Maybe something is loose?

 

sorry for my stupidity DV? diversion valve ? or somthing? i was looking at all the hoses and nothing..... its sunday so the bastards are closed... i really hope they didnt beat on my car. i forgot to check the mileage when i went in... im gonna call them monday. because they should have only drove it off the lift and parked it. so idk how it just changes in .0000005 miles...

 

DV=diverter valve aka blow off valve.

Any way to check if they messed with your MBC? Maybe someone messed with your boost settings when they test drove it after the install.

 

why would messing with the mbc make my bov flutter like that? it did seem like maybe it was a psi and a half to high.. but idk..

 

but anways how would the boost setting make the bov surge?

 

ok i checked under the hood one more time. guess what. the **** took off my bov and put it on upside down......... now during a clutch install does it require popping the hood... i think not. they got some major explaining to do when i come in there bright and early tomarrow. im soo pissed. i took pictures of it on upside down . but i immediateley put it back to normal. does anyone no how this will effect my engine im worried. ... its been about 100 miles

 

Let's see the pics! How do you put it on upside down?

 

ill upload them in a bit i gotta send them from my phone. but basically you just flip it upside down and reverse it and put the hoses on the other ends and yea upside down and backwards.. but i want to know why the hell they even touched my bpv..... that has nothin to do with a clutch install

 

Don't worry, I'm sure no harm was done. Not 100% sure on this but mayb they had to remove stuff under your hood to get to some tranny bolts from up top. Although, putting a bov on backwards is pretty dumb, good mechanics with turbo experience SHOULD know which way the air flows when a bov opens up.

 

When we did the clutch in my car we took everything out of that side of the engine bay. Battery,intake, intercooler pipes. Everything. Yes you do have to open the hood for a clutch install at the very least to bleed the slave cylinder. So don't go and get all pissed. Installing the bov in the wrong position seems like an easy thing for someone to do espesially if the shop you took it too is not very familiar with evo's. Save yourself the hassle of driving there, and wasting gas If you fixed the problem.

 

Was that a serious question?! Yes you have to pop the hood to install a clutch. You have to take the WHOLE transmission out of the car for this. Half the bolts are on the top and you would have to remove the whole turbo inlet system to get to it so they probably took it off and forgot which way it went. Not sticking up for them or anything because like someone else said if you have turbo knowledge or decent mechanic knowledge you should know or remember how it goes back on. But being a mechanic myself, I hate when people who obviously don't know what's going on with something or how something is done or certain procedures jumps to conclusions and automatically blames the tech for things. And if it was a good tech, there would be more than .00005 miles on it before and after. It's called a test drive to verify the repair, I perform one on any driveability repair to make sure everything is working as it should (which they would have picked up on the turbo surge during this, or think maybe it was that way prior since no pre-repair test drive was taken). Sorry for the rant, but I take things like this a little personal. If you flipped it back and everything is working correctly, like the others said, I wouldn't waste the gas going back or the time calling. It's fixed and nothing is going to be done except maybe an apology.
