I had to laugh! 45 years ago the first time I crawled under my scout to change the oil, there were two plugs. I was in a quandary, but finally said screw it and undid the one I thought was the engine. I assumed I'd be able to get the plug back before the whole thing drained if I made the wrong guess. Everything turned out fine (once I washed my hair with Dawn that afternoon). It was a learning experience. I told my husband he could have that job next time. FYI my son's 2007 Wrangler with a 3.8L engine is at 290,000 miles.
from what ive heard from other guys ive talked to they start seeing problems around 175k-200k mark mine is now at 194k and so far nothing major nock on wood mine is a 2011 which is the last year so im not sure if there was some updates between the 2007 and 2011
Most of them don't make it to 100k before spinning a rod bearing. The problem is the 5w20 oil. These jeeps are horrifically underpowered (mine is a 2 door manual and it's an absolute dog I can't imagine how bad a 4 door automatic must be) and spend most of their lives running around 4-5000 rpm. That oil is just too thin and it gets hot as hell, thins out and then a rod bearing grabs the crank and its game over. My advice is run at least a 10w-30 oil and install an oil cooler. Mopar called for 5w20 only in the US market do to CAFE standards. When these were sold overseas they called for 10w30 oil. To top it off the oil pumps are very small and can't supply enough oil to keep the bearings alive when the oil thins out. There isn't any high volume pumps available for these engines. Of course some of these engines last a long time but those ones are driven very lightly. Run it hard with the thin oil and it's not going to last 100k.
Nice to see you use mopar coolant.
Great video!

Mine is 140k, i use 5-30 to get the tick quiet, and i live in the cold climates and also helps with the tick.
How high in mileage you think these 3.8’s can go

My 2009 jku just rolled 200k. I have that lifter tick on startup. I live in Arizona, so no rust.
