JK 3.8 Engine Clatter

[justanotherguy]

I recently purchased a salvage 2010 JK with 150000miles. There is an engine clatter sound coming from the front upper driver side of the engine (sounds near the alternator area).

Any ideas what the cause could be?

All I hear is an exhaust leak

Yep, that's definitely an exhaust leak.

Those toilets are known for cracked exhaust manifolds.

These are the parts I used to replace my leaky exhaust headers:

Titanium Protect-A-Boot™ XL Ringless - 8" 6-Pack

Protect-A-Boots are made from a high temperature resistant basalt fiber material and treated with a proprietary coating, Protect-A-Boots provide spark plug boot and wire protection from extreme under hood heat and helps prevent burn-through, hardening and cracking of boots.

The spark plug boots are because ductile iron exhaust manifords are shorty headders. And I had the manifolds ceramic coated so I didn't have to worry about the heat shields.

Hope this helps...
