I've got 190K miles on my Jeep. No significant engine problems in the 10+ years I've had it.
But there is a knocking noise coming from underneath. It's not too loud when idle, but gets louder and accelerates as I accelerate. It still runs smooth and feel nothing out of the ordinary. I'm not very knowledgeable when it comes to "under the hood" stuff. The guy at NTB without looking at it said it sounds like a rod knock in the engine. So basically, he said it needs a new engine. My girlfriend's father who is a mechanic is looking at it next week and says it could be a rod, but it doesn't sound consistent with a rod knock and it has him somewhat stumped. Keeping my fingers crossed it's not the engine. Read a couple of things that said it could be something in the transmission. Just trying to research what it could possibly be for when we get in there. There's a video below of what it sounds like. Thanks for any help.
