What did you do to your Cherokee today?
instead of what did I do today, it's more like what have I done for the last month. Regeared to 4.56, replaced all ujoints bushings, bearings etc. Installed ballistic fab diff cover for the d30, Installed IRO trackbar, replaced rear main seal, rebuilt front drive shaft, currently working on rear disc brake conversion. Still on the list mount newish cooper discoverer stt pros, shackle relocation bracket and re boomerang shackles, smittybuilt winch, inverter, 4 port injectors, new radiator, timing chain. All these parts are sitting in my garage oh and wire up all the lights and winch. Lol things to order still... 97+ center console with cup holders, cb radio, bored tb, extended brake lines, hood vents. I'm sure there's more just can't think about it right now lol I should start a build on here but I document most of my work on Instagram: arizona_xj. That was a lengthy post lol sorry

I joined the Rotella fanbase! 198k miles on The Beast, last oil was Royal Purple. Don't remember viscosity. Got a Napa Gold 1626 filter to go with it. Next time I do oil I'm gonna drop the pan and check the pickup strainer, and check for debris at bottom of pan. But that wasn't done today. Just figured I'd put that out there.
Had a slight mishap, NAPA gave me the wrong filter, so had to go back. Also, 5 quarts isn't enough for the thirsty beast, gonna add a quart tomorrow

The 4.0, even with the stock filter, takes 6 quarts during an oil/filter change.

They use 4 quart (1 gallon) jugs because in many large truck engines, oil is measured by the gallon and not by the quart. I honestly wish regular car oil jugs came in 4 quart instead of 5, as I've had two small 4 banger motors, and neither one took 5 quarts. My ZX2 took 4 and a half, leaving half a quart in the bottom of the jug. My Cruze takes 4.25 quarts, leaving 3/4 of a quart in the jug. Honestly easier to use quart bottles in those cases.

Well I saw a coolant leak for the first time (only had this ZJ for a week). I was bummed, but after further investigation I may be OK. Today was the first time I used the heater and once I got to work I noticed a few drops of coolant on the ground. Opened the hood and it seemed to come from the water neck, specifically the heater hose connected to the neck. I tightened all the hose clamps on the hoses and drove it home 20 miles and no more leaks. I will do further follow up tomorrow to make sure everything is fine.

I'm praying (and taking many preventative steps) that I don't suffer the same or similar fates. I have been stranded one to many times on the trails due to some fashion of a failure. Always carried a backup driveshaft (front and rear) and two gallons of water to combat the beasts. My current I am changing directions and fixing everything BEFORE it becomes an issue. Next replacement is radiator and hoses
Good news being.... piston and rings still intact?

I don't use the Rotella in my cars anymore (apparently the 40 weight causes problems with variable cam phasers) but have found it to be ideal for ATVs. Of course, I'm still keeping my eye out for the right MJ.

Problem I run into with leftover oil in the 5 quart jugs, aside from a jug sitting around with less than a quart in it (minor I know) is that I use the bottles/jugs to take the waste oil I just drained to the collection area. Was convienient for my XJ, where the engine took the full 5 quarts, and a 4 quart Rotella jug just wasn't quite big enough, but not as convienient for my smaller engines that don't take the full 5 quarts.

I wouldn't mind having a nice MJ to add to the collection either...but that's down the road for me.
And the Rotella, just like other blends...are made for a certain engine type application. I certainly wouldn't run it in a little Japanese 4 banger. lol. But the type of plant the I6 is... does nice things for it.

Good news is I can reuse the pistons but rings, bearing and lifters will be getting replaced. If it wasnt for the stupid cracked head, I would be in the rebuild under $150. And that would be for name brand parts, not cheap china junk. Also helps having leftover spare Jeep parts.
