Re: WK 4.7L Driver's Side Exhaust Manifold & Gasket Replacement Writeup W/ Pics
Simple situation here, if it sounds like it has a leaky manifold, it has a leaky manifold. Could be a broken stud (local stealership parts guy says about 95% of the time manifold doesn't need replacing) only or a broken stud/warped manifold. Not much to test, fire it up and listen. If you hear it, you need to fix it. I suppose you can choose not to but it will get worse and eventually it will warp the manifold.
