thank you. for anyone else wondering, the maximum allowed warpage is 0.1mm (0.004 in.)

does anyone know what the tolerance specs are for the block? I may have overdone it with the green roloc disc and want to check with a feeler gauge and straight edge? I've searched everywhere but but can't get a solid answer. also.. yeah my hand kept slipping and there may be a scuff or two on...

I've asked a few mechanics and they all said if they were doing the repair, they'd just do the top of the engine and not worry about the bottom half. I'll be replacing the oil pump, chains, guides, tensioners, pickup tube, pan gasket, timing sprockets, water pump, radiator, exhaust and heat...

UPDATE: i have taken the heads to the machine shop (he's been in business 40+ years), he will do a valve job and resurface/ pressure test the heads. he says that parabola shape is not unusual and its where the water had been sitting due to the head leak. he seemed more concerned about my rod...

I had actually taken it to two mechanics for the misfiring issue 2k miles before the head blew. the first mechanic said my engine was very healthy and suspected carbon buildup as the issue, he performed a compression test and said they were fine. he did a leak down test and said there is a...

thanks for the brutal honesty lol I had just hit 120K miles before the head gasket failed. im gonna take the heads into a machine shop to have them worked on, but sorta paused everything when I saw the cylinder wall and ridges at the top of the wall. I can feel the ridges where the rings do not...

hey, did you figure out if your misfire issue was due to the rings on #2 cyl? i have the same issue with 2,4,6 but dont see how bad rings on cyl 2 would impact misfires on 4 and 6 as well.

my vehicle had similar issues. after shutting off the jeep, i used my nose and placed it very close to the fuel rail and fuel lines. the smell was noticeably stronger on the fuel line hose with two connectors on both ends (52100320AG). apparently the o-ring inside the quick disconnect portion...

can I get away with using a wool pad to hone it out or do I need to pull the piston out and buy those jingle drill honing adapters? I can't feel the impressions on the cylinder walls with my fingers and its relatively smooth. also, what can cause an impression such as the one im showing in the...

my head gasket blew up. cylinder 2 was soaked in water when I removed the heads. I also noticed piston impressions from the vertical movement onto the cylinder wall on #2. the impression is very smooth and I cannot feel the ridge with my fingernails but it still bothers me. there was no oil...

ahh. I couldn't sleep at night knowing that I bypassed an issue rather than finding the culprit. ill spend a few more hours on this heavy paperweight. will probably pick up a used junction block and slap it in there the wiring, other than the ORC module, was fine. I've patched up the ORC chewed...

that's what I thought. but replacing the ignition switch with a new one did not change my predicament. still no power to those fuses. many hours of inspecting the wires in junction with that dead ignition wire lead me to remove the driver side carpet and seat. somehow a rodent made a home...

so I did a resistance test from one end of the wire pin that goes into fuse box and the pin inside the ignition switch wire harness. both wires are good and have solid resistance, meaning they're intact. I noticed the fuses for srs are not sitting snug inside the spades. but that still doesn't...

hmm.. let me see if i can measure resistance on that wire before cutting it out. is it unusual for that wire to be faulty but when i supply it with 12v it powers on all my dead accessories?

bought this jeep for $300 with plethora of electrical issues. it's been sitting for a couple of years. after a year of fiddling with it, I replaced the pcm and it started right up. here's some quick history 2007 jeep liberty 3.7L 2WD limited, 114K, with a fair share of rodent droppings under...
