Exhaust leak
#11
On my 97 4.6L it was the exhaust pipe bolts where the manifold connects to the exhaust pipe. They just rusted through. Went to a muffler shop they burned the bolts outs after dropping the exhaust pipe. Replaced with 4 new bolts and nuts, 1 1/2 hrs cost me $125.00 Only had the noise when it was cold, then the ball and socket expanded the the noise left .

Just a piece of advice i learned in finding a leak is running seafoam through the brake booster, smokes like a bastard so it's easy to spot leaks. Thats how i found the one on my manifold flange. Easier if you have one person run the seafoam and another search for the leaks, plus it helps clean out your engine.

I've never had a problem with it, used it on tractors, bikes cars, trucks, push-mowers and just about anything else with a motor. Just don't leave it in the system for to long of course, it is a cleaner after all. i leave it in for 15 mins in whatever i'm using then start it up and burn it out.
