I got my Snap-On compression tester finally so I decided to give the 213k 4.0L a little check up! I'm very pleased with the results.
Cylinder 1: 177
Cylinder 2: 168
Cylinder 3: 165
Cylinder 4: 174
Cylinder 5: 183
Cylinder 6: 181
Spec in my Haynes manual is 120-150 PSI with a 30 PSI variance. I cranked the engine 8 times per cylinder, given the throttle wasn't wide open so specs are a little high, but they're all fairly close and looking in good shape.

Last time I looked the intake was very clean as well as the tops of the Pistons when I used my bore scope, but I may have some carbon build up now. I'll give it a can of seafoam tomorrow just because. Overall, I'm happy with the test outcome for 213k miles!

Finished my coolant flush today. Gave it another chemical clean, flushed everything out clean and put in a new stant 195* t stat. The overflow bottle had a little dirt in the bottom.. However it runs a bit cooler now at idle!

I got a package from Dirtbound yesterday but I open it to find they sent me the wrong bumper. They sent me the stubby winch bumper. They're sending me the correct bumper and I'll return the winch bumper. Sucks I'll have to wait a few more days.

Front bumper came off tonight, I'm painting the dirtbound stubby bumper as we speak! No pictures of that til it's done! But here's a pic of the jeep without a bumper and a fresh bath.

Oh how I love broken bolts. Guess I'll have to finish the bumper install tomorrow evening... The stock steering spacer had seen better days. Lol

Went to town and picked up a new bottle of propane being mine was out.. Also grabbed some 12" cobra pliers and they worked like a charm getting that bolt out! Everything's back together and the dirtbound bumper will be going on tomorrow after I get off work.
