On August 1st 2015 I was fortunate enough to add a second WJ to the Jeep family. A 2004 Jeep Grand Cherokee Overland in excellent shape from the previous owner 04Overland47. The Overland will serve as my primary daily driver while my original Blue WJ will stay as well. Maybe I can finally go crazy with the blue WJ one day. Anyways, I have some small things planned for the Overland and as time goes by I am sure that list will likely grow. :cool: Going to keep this Jeep, as I do with most everything I own, at top notch. This will be another fun journey!

Just a quick update, this is the smoothest Jeep I have had the pleasure to ride in going down the road. I was cruising along and didn't even realize I was doing over 80, effortlessly. The torque is ridiculous.

I have already added a USA-SPEC iPod adapter to the RB1 radio and it interfaced through the CD changer cable. Works pretty well and I am so far very pleased. The Infinity System is really nice compared to the base model system. I have some more audio upgrades coming, although will be keeping the RB1 and Infinity amp as it works just fine and the RB1 looks really clean.

This weekend I plan on getting some things done:
- Oil Change with Mobil 1 High Mileage Full Synthetic 5w-30
- Transmission fluid change with Castrol ATF+4 and Wix 4WD filters
- New Transmission pan with a drain plug for easy service next go around :cool:
- Valvoline Power Steering fluid that meets the Chrysler MS-5931 (turkey baster method, and I have a gallon of the fluid I am going to cycle through)

Why do you get all of the Jeep luck? Where was this when I was looking for a replacement a few years back? I ended up with a Toyota. Yes, so you should feel guilty. :p

Great looking Dub, snowboy. Now, it's time to get to work. Btw, I've been running same Mobil 1 in the 4Runner. It's great stuff. I know Amsoil is supposed to be better, but you can get Mobil 1 for around half the price. Amsoil has priced themselves out of my budget. Enjoy the WJ!

For the trans pan are you just thinking the Dorman one from Rockauto? I know PML makes a trans pan but it's realllll expensive. Just curious, as I've been thinking about doing this too.

I have been running Mobil 1 for years now in most all of our cars. Oil analysis to boot as well, always came back good. I do not know about guilty, but I feel pretty lucky! :cool:

Hey man, I went with the Dorman pan of off Amazon for about $22 shipped. Can't beat the price and it has the drain plug as I said previously. Going to be worth every penny the next time I do the trans fluid. PML was just way out of the budget, unfortunately.

So you're gonna put 35's on it, right? :cool:
HAH! Don't think I will be doing that for a long, long time. The Blue WJ may get 35's down the road! :laugh:

First Oil Change, Check. Mobil 1 5w-30 High Mileage Advanced Fully Synthetic with a Mopar Filter.

Transmission fluid change, filter change, and new pan, Check. Dropped the pan, spun off the old filter, pulled the old pan filter. Spun on the new one hand tight, gave the new pan filter a good whack to seat it. (The o-ring thing was seated on the valve body before putting on the filter.) New pan installed with drain plug! Added about 7.75 quarts back to the trans to get it to the appropriate hot level.

Ran about a gallon and a half of the Valvoline power steering fluid though, going from pretty brown to light brown. Have more to go there. Doing the turkey baster method. Didn't and don't really want to pull the lines.

Swapped out some brake fluid, basted the reservoir and filled with fresh fluid x3. In preparation for bleeding out the system. I believe sending fresh fluid through the lines is better than sending the old fluid through and then clean fluid.

Road tripped today from Williamsburg to Pittsburgh and the V8 took the highways and hills without skipping a beat or evening sweating. Cruised between 70 and 80 mph with the trunk pretty loaded and managed 19.6 mpg "by-hand" calculated. I would say that is pretty darn good and the motor is running strong and well. I know my 4.0 WJ didn't hit those MPG numbers because it had to work so hard at those speeds and downshift more frequently. So the V8 will definitely do better on fuel!

At 75 on the highway, my 4.7L downshifts if it even smells a hill coming. Using the cruise control is an exercise in frustration as it doesn't downshift until it's bled off 6-7mph, then it takes it's sweet time holding the gear before it upshifts. Not sure why this is the case when I'm only on 32s - I didn't think re-gearing would be an issue until I was on 35s.

I think my 190K 4.7L is pretty tired and down on power.

Wow that's a difference for sure. Even on extended grades it maintained speed without even the idea of coming out of 5th. I heard the cruise apply more throttle of course but it wasn't enough where it needed to downshift. (The exhaust has a noticeable tone change while under load.) Only thing I noticed was the engine temperature went from about 198 to 205 on the grades. Never touched 210 though which is good. Maybe the difference lies with the regular and HO 4.7.

There are 245/65/17's on it, which I think are about ~30". The grades were not anything crazy, I do not recall there even being signs warning for steep grades.

That's quite a difference from 32's, and again, you have the HO verses the regular 4.7. You'd be surprised how quickly bigger tires will bog down an engine. I forget the formula, but you lose a percentage of torque with increase in circumference. Depending on what you use your Jeep for, it's always best to weigh the size advantage of your tires with your daily needs and the negative impact they'll have on your power to the ground. I had 3.73's in my ZJ, and just going up to 30's made it a dog. I imagine the HO you have can handle a lot more, especially as close to sea level as you live. What do you plan on doing down the line as far as tire size goes?

No lift or increased tire size planned for this Jeep. Being at sea level or close to it, helps!
4.7 235HP / 295TQ
4.7 HO 270HP / 330TQ
Tuned 4.7 HO 295HP / 355TQ (estimated as of now, have friends with a dyno that is currently being built/installed)
All of the above at the crank under the ideal conditions. But looking at numbers, there is an advantage.

I've pretty much resigned myself to the fact that I'll probably have to do an engine swap at some point in the next year or two. When I first bought it, it burned oil pretty bad but an oil change to high-mileage synthetic seemed to fix it - until I got on the trails and went into 4-low, then the blue smoke reappeared. And that's pretty much the way it works now - no smoke on the roads, bad smoke on the trails. Such is life.

I read up a little on maybe doing a 5.7 Hemi swap, but apparently that's a nightmare conversion. I also thought about an LS swap but that feels a little traitorous. I've thought about going with a HO when the time comes, but they're significantly more $$ than the standard 4.7, which I don't think is really worth just a 35HP/TQ gain. It surprises me that there's not more aftermarket performance options for the 4.7l, given how prolific they are. I'll probably just swap in a remfd standard 4.7 - keep it simple. You don't really need that power on the trails anyway, and if I want power on the street, I'll take my Caddy (STS-V :2thumbsup:)

Do you think it is your valve seals or piston rings? Wonder where the oil was getting into the combustion chamber from. A new/reman motor swap in would be a pretty penny but I'll be the performance would jump.

The Hemi swap has been done but like you said, it is a nightmare.

My bet is rings since it happens while the engine is under load and not just at start up.
