Well, sorta… early JK 3.6 cylinder 2 issues are from a bad cylinder head molding process, and there was a recall/maintenance service bulletin. I had that done myself. It was covered by the recall. If the head gasket can’t seal right it will cause issues down channel issues such as cooling.

as someone who is looking for a wrangler as a toy pretty soon, this is good info to know. thanks for sharing

Exactly!

You can even replace the rocker arm closest to the can gear doing it this way? I assume you replace them one by one, as you rotate the crank and get the lobes to point up? Also, where do you mark on the cam and chain?

I’ve seen this hack, and I believe that removing the cam shafts as done in this video isn’t THAT much more work IMO. Also the cam shafts are relatively cheap and worth replacing too. Especially if the cam damage from the bad rocker is significant, which it can be, and will cause issues. They also likely have 100-150k miles on them. Also delicately removing the rockers with the cam pushed over takes patience and time. Especially the ones close to the timing chain. Anyways, it’s one way to do it, just not one I’d do myself. I’d also say going all out and removing the timing chain cover (technically the proper way) is a bit absurd, so this video is a good compromise.

Wanna make that 17?

@@harrycallahan686Haha! Made me laugh.

Thanks I'm going to look into this!

Do you have a link for it?

@cody morris just Google search Baxter performance and it will bring a link to their website. They're the only one making them as of my knowledge. You'll enter in the year, make and model on their site.

I modified mine - Baxter Performance - no more dry starts

Food for thought. All this full synthetic 5/20 0/20 oil.... I always go with a synthetic blend and something thicker...just sayn

I appreciate you. Hopefully I’ll get there with the likes! Time is valuable, so I try to get straight to the point.

@@jackhfletcherhow much is that fix for the jeep wrangler I have the Same problem

$2500

Not if the Dealership is making $2,500.00 to fix them Too bad Chrysler, Dodge, Heep, & RAM can't build quality Valve Trains that last 250,000 miles like Toyota.

If you need more help, I recently posted another video doing this repair step-by-step on a Jeep Wrangler.

This is the question I’ve been asking.

@@jackhfletcher Thank you!!

@@jackhfletcher any view on Melling rocker arms ? (MR-1332). Any upgrade compared with oem ? (they're 40% cheaper than oem)

Let me know if you find a place, I'm also in SoFlo too. I'm actually headed up to SouthEast Jeeps in Stuart for some mods but I'll see what they quote me

No, because as long as the marks on the chain align with the marks on the sprockets, then the timing is good. On the front of the camshaft there is a little dowel pin, so the sprocket can only go on one way. By turning the camshaft, I was actually lining everything up properly. I’m not sure if I answered your question.

Transmission

Common problem from 2011 till 2016

Did you find how much cost this

A lot of different vehicles tend to do that after sitting. I wouldn’t worry too much about it.

Was it expensive to have it done?

About $3500@ the jeep dealer

Have you done any work to it recently? If so, what all has been done?

@@jackhfletcher while i did the rocker arms i lifters i also replaced the pcv valve and oil cooler housing

If the overheating didn’t start until you replaced the oil cooler, then you probably got air in the system. Take a flat head screwdriver and open the bleeder valve on top of the thermostat housing until you get coolant running out. I recommend using a spill free funnel and putting it on top of the radiator and filling it with coolant. Start it and let it run and warm up and then shut it off and let it cool down. You may have to do this a few times. Then remove the funnel, reinstall the radiator cap and go for a drive. It should be OK after that. As for the misfire, if you still had a cylinder two misfire before doing the lifters and rocker arms, then the problem probably lies elsewhere. But if the cylinder two misfire did not start until you replaced the rocker arms and lifters, then I would go back and double check all your work. Make sure your coils and injectors are plugged in properly, etc.

@@jackhfletcher i just bles the system but still no heat and it starts overheating. Once the fan kicks in it starts to overflow on the funnel

It shouldn’t do that. Something probably wasn’t put back properly or something got damaged. Bank 2 sensor B is the driver’s side exhaust cam. Check the cam sensor. Make sure it’s installed properly and make sure the wiring is good. You may have to pull the valve cover and see if the sensor or the target wheel on the exhaust cam is damaged. Actually, I just realized as I’m typing this that more than likely the timing is off if you removed the timing chain. Double check the timing.

@@jackhfletcher no actually a friend (mechanic) did it for me and didn’t remove the chain

@rbjackpotslots4842 Check the other stuff then. I’ve done a bunch of these and I’ve never had to do any type of re-learn.

@@jackhfletcher ok thanks for the quick reply I screen shot this I will show him thanks again

@L0C00L I just got quoted between $2K and $4K

You’ll always have a little bit of valvetrain noise so since you replaced all the rocker arms I wouldn’t worry too much about it.

It’s good enough. Every mainstream oil on the market nowadays is good.

Yes.

I have never experienced that. I have replaced my jeeps rockers numerous times.

this problem is notorious in the 3.6 or even 5.7 pentastar engines

The rocker arms are cheaply made and the roller bearings fail. I guess you could say the cause is poor manufacturing quality.

Too bad Chrysler, Dodge, Heep, & RAM can't build quality Valve Trains that last 250,000 miles like Toyota.@@jackhfletcher

⁠@@rc846ford and GM have the same problems with the rocker arms due to them outsourcing parts. Just stfu already and go watch Toyota videos. This is like you’re 6th comment saying the same shit 😂

Couple thousand, $2,500 seems like an average price for some shops with parts and labor

Get your hands dirty I know it seems like a big job and scary but it’s not too bad and you can save a few bucks the parts are pretty cheap and you don’t need super expensive tools

How much did that cost, if you don't mind me asking?

@@user-yy7id3oy1y Too much. lol. It was about $3,100. I took mine to a private mechanic too, not a dealership. At a dealership, it probably would have been $5k+. But again I had all camshafts, lifters, and rocker arms replaced. One camshaft alone for the 3.6L is like $450 right now just for the part. Multiply that by 4 and you’re already at $1,800.

@@gabewl29 that's not as bad as I had thought it would be lol. When I had the lifters replaced in my 14 Wrangler, it was almost 3k a couple years ago. But that was at a dealership.

I’d stay away from any Chrysler product.

Agree with the other comment. Stay away from Dodge Jeep Chrysler... I've had all 3, last being a jeep my wife got and dealing with this headache now. $2500 under warranty.

Oem? The oil filters pathetic design was always the issue.

👍 THX@@LJC370

No. I’ve never seen a 2.4 with this problem.

@@jackhfletcher can i send you a video

can i send you a video@@jackhfletcher

The book time is around 6 hours I believe. That’s pretty close to how long it took me the first time, but I can do it quicker now.

@@jackhfletcher thanks. I've got the exact same issue developing on my 2015 Wrangler at about 74k miles.

@@jackhfletcher What does this cost to repair, typically?

Those camshafts are about $500 each. The rocker arms are about $12 each. Plus gaskets, etc. So it depends on how many camshafts are damaged, if any. If only one is damaged, you’ll probably spend around $1500 or so.

Do you know if the extended warranty covers it?

No, they’re supposed to be relatively quiet. If you hear a lot of tapping noises then there’s definitely an issue. Sometimes it will progress to the point where you’ll get a check engine light and the vehicle will start misfiring and running rough. On the Jeep in this video, it actually hadn’t progressed to that point yet but it was just loud.

It depends. Just for one side of the engine, the lifters and rocker arms are about $260 in parts, and the camshafts are $500 each. Then expect to pay about 5 or 6 hours of labor.

2 shops told me to replaced engine around 8k to 10 k I opened the top and found the same rocker arm is bad

@@armingelloagan5216 this gives me hope because I just got told the same thing

It won’t once you get 70-85k it comes I changed my oil every 5k and did nothing. My friends have the same problem

I've heard that the problem lies with the cartridge type filter, that it drains oil out of the top of the motor too quickly once the engine is shut off. There's supposed to be an adapter to where you can use a canister type oil filter, that have an anti-drain valve in them to keep oil in the top of the engine once shut off.
