Well the weired clicking noise coming from the engine compartment has been found. There is an exhaust leak coming from the end of the passenger-side header where the header attaches to the rest of the exhaust with a two-bolt (three-bolt?) flange. Right at this flange, there is a NASTY leak. About one whole side is leaking. The pipes just dont fit right together I guess. I put some heavy-duty exhaust sealant on it and it quieted it down a bit, but after some offroad fun, the mud and water washed off the sealant. I'm having trouble getting the two bolts off without stripping them. I dont know how to plug that leak and I'd rather not have to pay some exhaust shop to do it.
Any ideas??
