That's all there is to it. I'll let you know how it holds up over time.

Mine cracked on the Drivers Side about 6 months ago (~55,000 miles). I just ignored it then because I'd heard it was a common problem that had a high likelihood of reoccurring if I replaced the the exhaust manifold. But, it needs to be taken care of.
Going to head down to Pepboys or Autozone today to find some ThermoSteel and patch it up.

Did mine today on driver side, crack was hairline, but patched it up with ThermoSteel. Was just wondering has anyone had this problem with the passenger side manifold? I was thinking of just removing the heat shield and cheking it out.
Thanks

I have to fix mine as well. Do any of you think your gas mileage got better after fixing the leak. My MPG is terrible and seemed to start when this occurred. I've been putting up with it for at least a year but didn't realize what the problem was. I filled up today and went 278 miles on about 18 gallons.

Thanks OP!
Thanks to this post I am in the process of giving QuickSteel a go. I sprayed PB on the bolts, pulled the heat shield and found this sizable crack. At 6:30ET I hope to turn the key with a successful seal and quiet manifold! I only have 39K miles!
