I was driving after fixing the map clamp yesterday. Pushing the car kinda far but while travelling home I suddenly start hearing a hissing sound and loss of power almost like its hesitating. There is definetly a loss of power but its not throwing a CEL. What could it be? I don't see any leaks anywhere and all of the fluids are at the proper levels?? I didn't realy notice a leak in the exhaust but again haven't had alot of time to look..

 

That sounds like a leak. Its a turbo car correct?

 

Yep. I started in when I got home and the sound, I think is coming from somewhere off of the turbo/charge pipe connection. The charge pipe feels looser and when I started the car and popped the hood I could hear the hissing and when I applied presssure to the top of the charge pipe, pushing it down toward the turbo it went away. I couldn't feel a leak though and the connection seemed tight..

 

put your hand down there and see if you can feel a breeze

 

I would but its pouring outside here. Its a difficult charge pipe to tighten down. I am just hoping its not a serious issue or something else. I have had nothing but problems so far with this install and considering it didn't throw a CEL I am trying not to stress out to much.

 

I have a leak somewhere also. I looked under the car and oneof the bolts fell out where my DP connects to the exhaust. Maybe try checking that out?

 

I willl check everything out whenever I can get a chance to get out there. Its ben raining here forever lol Getting a day off or even getting time off in the daylight is difficult.

 

check the piping and even the bolts holding youre turbo to manifold just re check everything and tigthen up accordingly never hurts to double check the whole install

 

I think its coming fro mthe actual housing of the turbo or DP. I can't see any loose bolts but I put pressure on the actual turbo filter and the sound went way then to. It must be underneath it somewhere. Anyone ever have this happen??

 

I took a listen under the car and was moving the DP around and it sealed up the leak when I pushed it into or toward the turbo housing. I am guessing that a bolt or 2 came loose on the flange. Could this result in a loss of power and torque in the midrange??
