The Restore didn't seem to do much to quiet it, so my uncle kept driving it despite the noise. Today, the engine blew. I don't know what happened exactly; I'll find out soon though. The 4.0 only had about 170k miles on it.
My engine has ticked for a little over 2 years now. Since changing from M1 TDT/ M1 filter to PYB/ Mopar filter it has been much quieter.. A slight tick on start up and within the first few minutes of use. It always goes away once to temperature.
