lhrocker Posted July 27, 2007 Share Posted July 27, 2007 I just noticed that when my 97 Legacy is cold (even on a hot day), when I step on the gas, there is some "rattling" under the hood. The noise sounds like it comes from the front of the car, but not really sure. I had all of the fluids changed when I got the car 2 months ago. There is no binding and no CEL's are coming up. I'd like to nip this at the bud as it currently has 127k miles on it. I did have an oil change with Mobil 1 a couple of weeks ago, but I didn't really check the level since. I had Mobil 1 since I bought the car and didn't really notice the noise (i'm a rollup the windows, turn on the AC and blast the music kinda driver. Any help would be greatful.

86BRATMAN Posted July 27, 2007 Share Posted July 27, 2007 Check your exhaust heat shielding. It gets loose over time and will rattle very badly. Quote Link to comment Share on other sites More sharing options...
NoEyeSquareGuy Posted July 27, 2007 Share Posted July 27, 2007 Check your exhaust heat shielding. It gets loose over time and will rattle very badly. +1. I clamped mine back down, but they'd only last a few weeks at best without being retightened. I ended up chopping off at least half the shields with tin snips(took a while), but much quieter now.

86BRATMAN Posted July 27, 2007 Share Posted July 27, 2007 On my moms 98 legacy, I removed the majority of them (carefully) with my cut of tool. Just cut off the bolt locations and straps and they came off relatively easy. Quote Link to comment Share on other sites More sharing options...
Commuter Posted July 29, 2007 Share Posted July 29, 2007 Another vote for heat shields. See the FAQ sticky for some ideas. Commuter Quote Link to comment Share on other sites More sharing options...
lhrocker Posted August 5, 2007 Author Share Posted August 5, 2007 I got it checked out today. It turned out to be the pipe segment between the catalytic converter and the muffler. There was also a heat shield that was loose. Cost me $200, but the car is now quiet inside and out. Another vote for heat shields. See the FAQ sticky for some ideas.
