Cracked Heat Shield - Help me Repair

[Horatio]

Hi all, I had a heat shield on my '99 Civic (hatchback) that cracked around one of the fasteners. I removed it because it was making an annoying noise. The heat shield I removed ran under the oil pan and I realized a couple of weeks ago that removing it may not have been the brightest idea so I've bought one off a wrecked '99 Civic to replace the one I removed. The trouble is that it too is cracked around one of the fasteners and I'm pretty sure that if I install it, it's going to make noise. Since I don't have any welding equipment, I can't simply join the metal back together so I'm thinking I may just use a wide washer to clamp the area and hopefully keep it from vibrating.

Anybody fix an issue like this?

Thanks

Greg

Some folks have been known to use large hose clamps to tighten around heat shields.

That was Ford's fix for my buddy's Tempo. Biggest "make a clamp" I've ever seen made ..well, almost.

Clamps work on exhaust shields well enough. Go back and RE-READ original post and you'll realize it's totally N/A in this application though.

Sounds like oversize washer pulling larger area around fastener down tight would be the best fix available, without taking shield to a welding (or like me, a muffler shop) to have crack repaired before installing.

yeah, it's normal for the heat shield to crack due to the heat. I forgot to put in one bolt out of 4 on a mitsu mirage a few years ago. I had vibration and rattling out of the yin yang. I put the rusted nut back on, vibration and ratting was gone. alreadygone, what part of Arkansas are you in? I'm from Memphis, TN

i once used stainless steel wire, wrap and tight heatshield on my old 94 accord. it stop the noise for 2 years and work very well, then i have to redo it because the heat/cold cycle broke the wire. i was a poor student and cant afford the $160 dealer was asking at the time.

The heatshield on my 02 Accord cracked last summer, but it was at the rear, underneath the seats. Screw it. I took it off and haven't noticed any problems with it since.

good replies, thanks all.

I thought about the hose clamp but due to the shape of the thing and where it's cracked, I don't think I'd be able to get pressure where it's needed to prevent vibration.

I hadn't thought of taking it to a muffler shop; maybe I'll look into that. I doubt they'd charge much for it.

Thanks again!
