slidewaysmike Posted January 28, 2009 Share Posted January 28, 2009 So I hope this is the correct forum for this, and if not I apologize, but I need some advice. Background: 05 LGT 5MT.. 68k... have owned it since new... kept pretty good care of it over the years. I've had the random CEL and had it checked a few times by the dealership... was told that it was wonky sensor on the intake side of things, but that it wasn't anything to worry about however I could replace it but that it wasn't a warranty issue... so I chose not to as the service guys said it was not an issue. So about a week ago, my friend the CEL comes on, and then goes out after about 3 days... I'm thinking, "Okay... must still be this 'nothing to worry about' as the car did nothing weird and drove just like normal. Then the next day it comes on again, and so I decide I'd better schedule a visit to the dealership. Can't get it in for a few days.. no big deal. Then 2 nights ago I'm minding my business driving down the freeway and I start to hear some weird noises coming from the engine bay. They started out as little extra whistles every time I let off the gas, and within about 3 miles proceeded to devolve into hideous whistling noises each time I let off the gas... and power was way down. So I assume that there's something wrong with the BOV or perhaps I've developed an air leak in a hose somewhere between the turbo and engine. I limp it home very gently, and park it in anticipation of a visit to the dealership. I popped the hood last night (service appointment was supposed to be today... but that fell through thanks to the sweet weather we're having here in Ohio) and decided to just check a few things and see if I can find a problem. Weirdly it's making no noises when i start it up.. let it warm up and drive it gently around my block... no noises. CEL light is off at this point. I decide to test it out a little and take it out for a little drive, and after about 5 minutes on the freeway the whisling resumes and the CEL comes on. Great. So I limp it home, and as I pull it into the garage, I start hearing an even more disturbing noise... a rattle that I've never heard before from under the hood. I turn the engine off, and want to vomit. Today I turned it on again, and pop the hood... disgusting rattling noises fill my garage. I put my hand on the turbo (thinking the turbo is the culprit because it's coming from that side of the engine) but it doesn't feel like anything is amiss... upon closer inspection I now feel like it sounds like a cat is breaking up just south of the turbo and pieces are rattling around in the exhaust...but can't be sure. My dealer appointment isn't until next week now, and I'm going to have it towed, but wanted to ask the experts here if there is anything simple I can check to help diagnose my problem? I just don't want to stress all week and weekend long about it if I can sort of figure it out. I just don't want to drive it. Any ideas? Link to comment Share on other sites More sharing options...
