Yeah, same reason I'm doing this one. I have the heads at the machine shop right now, so once they get back I'll be doing the reinstall video. Decided to stick with the motor, the cylinder wall grooves were easily polished out with 2500 grit sandpaper so it should be fine

That's the plan, also some good practice if all goes well to hopefully get to dive into the GT500 motor down the road.

Hi, I’m a qualified automotive Mopar technician with factory/dealer training.. You say you have a misfire on CYL 2. You think the coil, HT lead, S/plug, injector & wiring are all good.. Have you done a compression test (just testing one bank - 3 cylinders, would be adequate) or a leak down test.? If you believe the IGN & IJN (Ignition & Injection) systems are good. I would highly recommend performing at least a compression test on the R/H bank, before proceeding further. Kind regards, Your friendly Mopar tech

The carbon on a valve seat and stem, a loosening exhaust valve seat, a collapsing lifter (you would hear the individual ticking of the rocker), or a leak into the cylinder from the gasket (slow coolant loss) could be the issue. On mine, carbon built up on the intake valve stem, the valve was stuck open on a random cold start up, the rocker fell and rolled sideways, then smashed into the lifter seat/galley area and broke the aluminum head. NO it is definitely not a direct injected engine (haha), but age will have massive carbon build up on the valve stems. OF COURSE the stem seals are SHOT at this point and more of the culprit. I change the stem seals of my older 90's Hondas at 100,000 miles, but a 4cyl old Honda is a simple car to work on, way more than even a Toyota. Liberty death all leads to the valve stems, seals, and lifters. People blame the lifters too much - it is carbon likely 50% of the time. The owners who have a 3.7 Liberty and pop off their valve covers more than one time to re-position a rocker are playing Russian roulette. The valves are sticking. Definitely check the compression, but this could be a valve no longer sealing or a carbon loaded compression ring or scored cylinder walls. It will be an issue with the head no matter what. If you Ohmed out your coils and have clean injectors it is valve and head related.

I didn't replace any of the tensioners, if you go this deep I'd say go ahead and get a new timing set and replace everything, however I was on a tight budget, so I only replaced the timing chain guides. The valve train looked good, so I only had the valve seals replaced when the heads were decked. I an NOT a professional by any means, so I honestly don't know what a failing lifter looks like, but no taps or knocks when the engine was running prior to disassembly made me things everything was fine for reuse there.

Google coolant headgasket test kit, follow the directions and the results will let you know

No. Mainly because if it was warped it wasn't going to come out anyway. So no point. Usually the heads warp being aluminum, it's pretty rare for the cast iron to warp enough to cause an issue from my understanding. Been running fine since the repair.

Likely you'll need a new sprocket, I'd do a whole new timing kit. As for getting it off, there is a tool clamp the camshaft and keep it from spinning. The other thing you can try is several locking plyers. Use a cloth to keep them from marring up the cam, and an impact gun will also do wonders to remove it.

I've had good luck with rockauto, just need to pay attention to quantity and what's included.

@@AllThingsBoost Thanks so much!

I stuck a pry bar through the balancer to wedge it against the frame so it wouldnt turn when I was turning the bolt out. The other thing I've used (but not on this vehicle) was a ratchet strap wrapped around the balancer and that also held it in place to get the bolt out.

Where did you get the tool to take off the harmonic balancer off

It did turn on, however it ran poorly, over heated and when the spark plugs were pulled there was coolant on the front 2 passengers plugs. Definitely a blown headgasket.

Install video has been up for a while, check out the 2010 jeep playlist. So far the headgasket job has been holding up well

@@AllThingsBoost How long did it take you to do the whole job (tear down and reinstall)? 40hrs?

@@Humorem15 probably about that. The over all job took about 2 weeks waiting on the machine shop and parts to arrive as I found things I didnt initially realize I needed to buy.

Watch part 2, new bolts and tq sequence

Okay thanks

Danger? No, but it'll take you longer than a weekend if you are getting your heads resurfaced. Total time I had into this job was probably about 3 or 4 days, but it took me about 3 weeks start to finish waiting on parts and machine shop times while working on it in my free time.

I dont know.

I used 2000 grit sandpaper to smooth over the bigger ones, seems to have worked fine. 2k hardly takes off any material, just enough to make sure it wouldnt further chew anything up. If it was vertical scoring it would probably need a rebuild, because that would mean the rings are probably damaged. But mine was from an over head and swelling the aluminum pistons, thankfully they shrunk back down and didnt hurt anything

For removal? Sure, shouldn't hurt anything

Yeah, not much I can do now, but I'll mess with sound balance next time

@@AllThingsBoost all good man, very useful information and great video it helped me out personally. Liked and subbed.

I'm not sure. This is the only one I've worked on, it isn't a vehicle I'm very spun up on in terms of common issues

You'll be fine. Just pay attention to retimimg it and all will be fine.

Trackin, hard to get music balance right because everyone has a different sound system, I'll mess with some stuff next time around. Thanks

@@AllThingsBoost i think its fine man

@@AllThingsBoost Don’t need the music at all. Tell us what you are pulling off! Retired mechanic of 50 years.

Obviously it was not intentional, it's hard to tell in editing, even now on my speakers it sounds fine. In future videos I have fixed it.

Sorry bud, not going to pull the video down, figure out how to edit it, and reupload. It's been addressed in newer videos
