Exhaust manifold leak
Should I just have headers put on and run dual exhaust? Would I need two new catalytic converters? I've been looking at magnaflow cat back with duals straight out the back. Is it expensive?

Is it the exhaust manifold leaking or just the gasket?

Customer reply replied 10 months ago
No idea. I hear the noise and recognize it to be from just one cylinder. It's louder at a cold start before the metal heats up, and when the engine is working harder
Ford Mechanic: Gunvir Singh,

Exhaust leak with engine cold usually point towards a worn exhaust manifold gasket.

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

Jason V.Kirkland, WA

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey
