Spark plug knock or something worse?

From what I've heard speaking with 3 different jeep guys. One of them being from 505 performance. The 3.8 is horrible with heat. It's like it was designed to manage heat in the worst way possible. Everything just over heats and wears out. It doesn't move enough air for what it's worth. There's a HO 3.8 from 505 and 4.1l conversion that solve most if not all issues the stock 3.8 has in the jeep.

Thanks Saharacon! I'm interested to research what 505 did to address the issues with their HO & 4.1L builds...
 
Welp looks like a new Engine. Had a good feeling this would be the case. But wow. What carnage....

Thinking i might install the new 3.8 ho myself if this engine warranty through mopar isn't voided for garage installation. Guess 505 can hook me up with mopar warranty thatll cover all future failures so long as I prove service records. Sounds like a good option. I want to drop an extra 8k on this and just LT swap it.... but that'll be the next jeep I guess hahaha

I washed what I took out anything in there I didn't want to touch due to the lifters being exposed. But yeah I plan on degreasing and washing the entire engine bay. Thinking I'll Monstaliner the jeep soon. I live in Michigan rust is my biggest enemy
