Yes I agree with the pressure issue, But I fixed the part where the plastic pipe was melt by the exhaust pipe, it wasn't all vapour plastic just a small piece, I joined bot size, so I cuted in the bad part but I joint after even I put a clam also. the rest of the vapour plastic is ok is no melted or any holes.

 

Found the P0442/P0455 Service Bulletin. Also added the link to comment #8 above.

If you can blow air thru the EVAP valve under the hood, replace that valve , it should be closed.

 

Yes I did, was working fine, BUT NOW... I think the clutch is burned because I engaged to the first gear and not move, I pushed the accelerate pedal until 3k rpm and did not move anything, but before stopping completely(is now not moving anything), I engaged and moved just because I move the car steering wheel from right left and left right constantly then the car start moving forward in first gear only, very slow, in the clutch I feel vibration, so now is possible need to replace the clutch disk and slave cylinder and the flywheel?
Does somebody have experience in replacing the clutch disk in the HHR 2006 manual 2.4 litter?

Thanks in advanced
