ok long story short the Xr has been running great lately until this morning. i got on it and i heard a POP....then my boost went to 30+ psi. WTF?? i checked every vaccuum line everywhere. when i looked my pcv was disconnected (blown out?) a couple lines were off the vacuum canister, a bunch of vacuum lines to the turbo had holes in them....i dont think all these problems were present last week...i cat hit 20lbs of boost in 5th gear at 2200 rpm. this is not right. i have to feather the throttle to keep it from boosting now because once it breaks the 1lb mark it goes to 30 in less than 2 seconds. any help? i think its a wastegate problem. btw its a 2.3t with stock garrett t3 internally wastegated turbo. the solenoid that goes to the wastegate is supposed to be encased in something but it isnt...never even knew it was there until i took off the VAM and looked.im getting a new turbo and manifold soon but any way i can fix it until then? only 70k on motor. vacuum reads 19 In/HG with a steady needle. i appreciate any help i can get. Thanks!

 

1st, there can't be any leaks on whatever vaccum lines run to the wastegate.

If "a bunch of vacuum lines to the turbo had holes in them" means the wastedgate lines have holes in them, fix that for sure. If at all possible run a line right from the compressor housing to the wastegate uninterrupted.

Sounds like you just overboosted and your PCV system didn't like it.

If you want to test your car for boost leaks I have a "3 fitting we can attach to your compressor inlet and pressureize your intake to find out the next weak link. LMK

Rick gillis is a super nice guy and a 2.3t fan. Can't go wrong getting one of these. He is in the north npr area.

 

the hoses that run from the fitting that the wastegate is hooked to .probably go to boost control solenoid more than likely are leaking relace or bypass them

 

They sure do go to that soleniod. If you bypass it as he mentioned it will make the lowest amount of boost possible which should be 9psi on a stock gate. Trying to keep the soleniod is cool just replace the lines but in reality the gillis is they way to go as it doesn't fail. The soleniod might have just gone bad.

 

what would i do to bypass it? when i touched the solenoid the lines broke off. so what should i do now? im definately getting the gillis next week when i get paid. thanks guys.

You take a peice of good rubber hose and make an uniterupted line from the fitting on the compressor housing to the nipple thats on the wastegate.
That should make it 9pds or so.

 

same sorta thing happend to mine. I went to home depot and got a regular gate valve... now i have redneck boost control just a slight touch of the valve and it either increases or decreases... take about 10 minutes to hook up.

 

ok.... i think im gonna try that. i'll give you an update. 9 psi is much better than 90 hahaha thanks everybody!
