Just did the patch with the JB weld. the heat shields come off separately its easiest to get to them from under the car. Don't waste time and just remove the plastic under cover and you should see a couple areas where you can get to them with a long extension.
Attempted to removed the heat shields today to try and patch the manifolds and the bolts holding them on were completely rusted and the heads just rounded off. Looks like I won't be able to try and patch.
Does anyone have know if the heat shields come off with the manifolds? My next step is to just move forward with replacing the manifolds. Appreciate any insight.
