aartod Posted October 18, 2007 Share Posted October 18, 2007 I have a '90 legacy and my while out on logging roads I have put a few dents and dings in my exhaust heat shield and now they rattle like crazy---and they are driving me crazy! all the bolts are tight they just dont fit like they used to, so I was wondering what might happen if I removed them? Anything bad? Would the increased heat melt any near-by componets or wires? I hope not because I would love to trash them! Quote Link to comment Share on other sites More sharing options...

I speak from experience with multiple Subies. Ive removed all of them on many a subie. Nothing going to melt Quote Link to comment Share on other sites More sharing options...
Rooster2 Posted October 18, 2007 Share Posted October 18, 2007 I have had the same problem on my 2 Subies. To fix a low tech problem with a low tech solution, I put the car on drive up ramps, with the motor running, I crawled under the car. Using gloves to keep from burning my fingers, I pressed and pulled on the shroud at various spots to figure out where the shroud is loose and vibrating. Once I located the spot or spots, I would take a hammar and pound in a good size bolt as a "door stop wedge" to stop the shroud from vibrating. I found this "fix" a lot easier then working to remove the shroud(s). It has been a couple of years now, since I have done this, and the bolts continue to stay in place and keep things quiet. If one does ever fall out, I will simply replace a bolt. It really takes less than 5 minutes to complete the work. Quote Link to comment Share on other sites More sharing options...
nipper Posted October 18, 2007 Share Posted October 18, 2007 Dont remove them, since you go off raod there is a chance of starting a fire without them. Several methods of repair, first is to go under the car with a pair of vice grips and tightn all the joints and seems. Second is to use lareg hose clamps to tighten the sheilds against the pipes at the end of the sheilds. nipper Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted October 18, 2007 Share Posted October 18, 2007 I've had good results with large worm-drive hose clamps to stop my heat shield rattles. Granted I needed about half a dozen of them per vehicle but it seems to working well Quote Link to comment Share on other sites More sharing options...
ericem Posted October 18, 2007 Share Posted October 18, 2007 Is it possible to spray some foam in between the heat shield?? Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted October 18, 2007 Share Posted October 18, 2007 I'm sure it is possible to spray foam in there, you mean like that foam sealant for cracks? I doubt it can withstand exhaust temps though and might smoke and/or stink.... Quote Link to comment Share on other sites More sharing options...
ericem Posted October 18, 2007 Share Posted October 18, 2007 Ya true maybe a high temp one? Some must be high temp up to 600-700F range. How hot does it get really? Quote Link to comment Share on other sites More sharing options...
johnceggleston Posted October 18, 2007 Share Posted October 18, 2007 somme of that stuff could be very toxic!! be careful. Quote Link to comment Share on other sites More sharing options...
nipper Posted October 18, 2007 Share Posted October 18, 2007 So you want to collect on the fire/theft part of your car insurance. If your going to do that, you need high temp insulation tape, then put the heat sheilds back on over that (which some people have done on here. nipper Quote Link to comment Share on other sites More sharing options...
fnlyfnd Posted October 18, 2007 Share Posted October 18, 2007 I had some type of foam stuff in my original heat sheilds (factory??). I just removed them a few weeks back and it all kinda fell/crumbled out. Boy am I a happier person. I tried some fixes but they never lasted.
