If it goes up noticeably, the rings are worn, if it doesn't, it's valves that aren't sealing perfectly.

Also, make sure you're doing the test with all 8 spark plugs out, hold the throttle wide open while cranking, and make sure you hear it spin at least 4 times for each cylinder.

Factory specs is 180psi for these, and somehow, mine still tests 170 - 175 on all 8 cylinders, so I'd be a little surprised if yours is actually that worn after 205k (mine has 143k, last test was done at 136k).
Thanks for the info!

The test was done warm, but I don't know any other specifics. I'll have to do the test myself some time to see, I'm just going by what the previous owner said.

He has a K&N intake on it, if that would help to differentiate between worn rings or valves. My thinking is that maybe slight debris has found its way in over time and worn down the rings. Would that make sense?

Either way, I bought it and drove her home today

The intake shouldn't make a big difference, but your thinking is sound (if the filter on it was crappy or poorly maintained).

As far as my ZJ, I washed it, polished it, waxed it and (yesterday) installed a front lip to hopefully help highway gas mileage and cooling slightly (can be removed in 30 seconds when the extra 2" of ground clearance is needed, just have to reach behind it, unscrew a couple wingnuts and pull it off).

Frustrating

Took my lifted (3.5" RE) to get my 265/75's mounted and guess what? They don't fit. lol Makes me start to wonder if many of the people who post on here really know what they are talking about. The fronts fit great but the rears.....not so much. When the jeep was on the hoist( suspension at full flex) the tires couldn't even be put on the rotors/hub as they bumped the front of the wheel well. The garage didn't know what to do so I told them to lower the jeep and jack it up by the pumpkin so the suspension flexed back into the wheel well. Voila...they were able to mount the tires so that I could at least drive it home. Will be ordering new control arms to rectify this problem. So FYI....you can not put that size tire on a 3.5" lift without control arm changes. Sounds like maybe the fronts rub a little bit somewhere but until I can get the rear adjusted properly I wont be driving it.

I'm pretty sure that even 31's would not have fit that lift. OH well. Live and learn.

Now...I won't be lifting this jeep any higher so should i get adjustable control arms or just the longer ones?

Installed a pair of 1" spacers in the rear



I think it looks better. Needs bigger tires though...

I'm sitting at ~4.25" of lift in the front and ~4.75 in the rear
Still running the stock t bars
I have both adjustable bars in the garage, i'll get to it soon.

Hmm, i wonder if your tires are like, big for 265s? Because i'm on 2 inches with 31's. Maybe its the bad angle of the old arms and on 3.5?

I'd suggest gettinf adjustable, just in case you ever change your mind.

* Upgraded the radiator to a three core.
* Changed the condenser coil, water pump, harmonic balancer & seal.
* Added new 1.75" rear isoators to the rear springs. ( ps: swapping the front springs to the rear does not raise the back enough to match the front with a RRO 4.5" lift. This includes changing them with new ones )
* Removed the roof rack and rubber strips.
* Removed all the decals.
* Treated the rust holes the rack strips created.
* Changed the front headlight header panel.

It's usually my luck that this sh*t doesn't work. I'm sure control arms will fix the problem but it's still a PITA.

This "simple" lift has turned into an ordeal. But if it had been simple then my fun would have been over in one weekend. Now it keeps dragging on and on and on.

Still can't get the steering dampener out. Have pounded on the damper, on the flange and PB blastered it with an entire can of PB.

So at least I get to keep enjoying working on my Jeep far into the winter sans a garage or all my tools. Although I may make a special trip 6 hours away to get the rest of my tools.

Perhaps then my "fun" will come to an end and I can start enjoying my new jeep. lol
