I was driving on the highway today with the windows up and I heard an exhaust leak coming from the engine bay on the drivers side. When I got where I was going I took a look under the hood and found 1 bolt about to fall out and another I could turn with my fingers. What are you guys doing to keep this from happening? I heard about the locking bolts or wiring the bolts together. Some people have used Teflon tape or blue loctight and tightening them down after heat cycling a few time until they stay tight. These bolts aren't exactly easy to get too. The teflon tape idea sound pretty good to me. Anyone try this?
