Hootbro, thank you for the schematic I used it to identify the relay for the key on circuit for the 12v cigar lighter. Pulled the relay opened the case and adapted the relay to constant on, this was so I can use a solar battery tender and never open the hood. Took all of 30 seconds to modify.
Techron Plus with PEA or BG 44K with PEA once every other month on a port injected engine is more than ample can be done less based on your driving. That is all I do and if it sits for a bit I add Startron, actually I do this every fill up as it encapsulates the ethanol which cause the most damage.
Check that the upper track bar bolt isn’t loose, most wobbles I have seen is because of this and it elongates the hole. If gone unchecked it will be the end of you and the jeep.
After the engine sits for an extended period, oil drains back from the filter and oil galleries to the pan. The ticking is the lifters until the oil pressure builds back up. Look up Baxter and drain back filter adapter for the jeep around $320. Or you can put your foot on the accelerator pedal...
