Exhaust leak

Hey guys. I have noticed quite a bit of exhaust coming out the engine compartment. I have been having issues with the ebpv. And I have replaced the ebps hose and sensor completely. The original issue I had was I found the hissing kicking on after warm up when going cruising speeds. I could feel it lose power. Hissing has stopped since I disconnected the connector at the valve. I’m getting around 18-20L/100km but should be getting around 10-11 from what I hear from previous owner. I have attached some videos and photos. Not sure where the leak is coming from but wondering if you can notice any issues from the photos. I noticed a lot of build up below the ebpv. Thanks guys

I'm having trouble seeing a leak....

You're looking at the IC couplers? There's no exhaust in there and the outer surfaces are typically oily so "stuff" sticks to them (the couplers themselves leak oil from the CCV fumes being pushed into the cold side of the turbo - something many of us eliminate with the "CCV Mod".)

Very common to have exhaust leaks at the up pipes where they plug into the Y manifold behind the turbo. Lots of youtube videos on this.

Just be careful if you are replacing the up up pipes. There are different ones if your truck is an early 99 vs a 99.5-03.
