68661147AA - Right Side Intake Camshaft

[ShadowsPapa]

On the old DOHC Honda motorcycles with cam oil issues, they would just modify it to run external oil lines from the bottom end directly to the head instead of messing with the stock passages.

Yeah, and AMC people used to drill and tap the oil gallery by the lifters and run a tube to the rear oil gallery believing it would prevent rear main failure - what a joke.
The problem was lack of oil RETURN to the pan. All they did was nothing because a hydraulic system like that runs equal pressure through the whole system. An engineer friend proved it by building a high performance engine, putting it on the dyno and tapped into the oil galleries in several places, including to the rear main. Pressure was equal through the whole engine.
The solution - baffle the pan, or add a 6th quart of oil. (or clean, polish and open up the oil RETURN passages from the heads to the sump)
The added line did nothing but make the owner feel really good.

For anyone interested in doing this repair themselves, I had ChatGPT do some research for me and it spit out this post on the Wrangler forum and gave me this video of a 2015 3.6L going through the repair.

Wrong engine. We have the PUG. Wrangler didn't get this engine until JL in 2018.
Anything prior to JL, or the 2016 model year for the WK2, will be wrong parts and some different parts.

That's the problem with those ai things - they just grab stuff from forums even if wrong because hey, it's a 3.6 Pentastar, right?

Backorders don't necessarily mean there's that many failures - regional depots and even dealerships may stock those parts, so it could be more than half of those are just for dealership stock.
It's hard to say that xx backorders means xx failures. It doesn't necessarily connect in these days of supply issues and so on.

You have quite the opinion here on a lot of topics but opinions don't solve problems. I'm solely here to find my parts that I need, not all your 2 cents.

Cool. Completely different situation.

Yes, from Honda, but it is just like the stuff going around on the 3.6 - people don't understand oil, oiling, pumps, pressures, or hydraulics at all...........

LOL - but my "opinion" isn't based on internet crap and people tossing mud at the wall to see what sticks (so far nothing) - it's based on experience and training and knowledge of oil and systems.

What I stated are facts, not opinions.
FACT - the intake lobes and followers are lubricated by spray from the exhaust lash adjusters.
FACT - oil loses viscosity as it ages - go check out some analysis reports, and the oil geek's comments - it doesn't gain viscosity.
FACT - pressure doesn't lubricate - it's a result of volume being forced against a resistance. Pumps are volume devices. Our pumps are multiple-volume pumps, not single volume. The volume is adjusted by the PCM for various circumstances.
Most what I posted was fact, not opinion.
There's a difference between those who know, and those who guess

What gets posted is the sort of stuff that gets copied "I saw someone on the Gladiator forum say it was this causing it" over to the Wrangler forums, then to all of the other numerous Jeep forums and fakebook groups.
The speculation is not helping at all. Spreading bad information is making it worse - like oil viscosity increasing.
People need to know how these are oiled and lubricated it will HELP THEM in these, and later repairs as they try to figure things out if they know exactly what oils what, and how our oil pumps work.

There's not a thing in the world that can help you get parts - deep backorders like that take a lot of time.
Best bet - "dealer shop".
There will be a dealer somewhere that has one on the shelf, or, knows where to get them. It's hard to imagine that every single dealership in the whole country has used up their own entire stock and all depots have empty shelves. Depots serve dozens if not hundreds of dealerships.
Find a parts person willing to dig. Slip them a C-note.
I've seen it work where a guy in a small dealership actually "calls around" - they did it for me when there was a shortage of the parts for the steering gear swap in 2020 - they found the parts and got them sent through the regional depot over to the dealership where my truck was.

Look ShadowDaddy, I don't doubt your knowledge in the industry so just cool it on the info policing for a moment.

You literally live in the middle of US car manufacturing and it seems you have a leg up knowing how the parts industry works on the back end. I do not have this luxury in knowing EXACTLY who to call and find the parts I need in a multi-thousand backorder situation. So far everyone I call tells me they don't have the parts and they don't know how to get them or when they will receive them. So unless you have a phone number of the person who just has these parts or knows where to get them, all your other comments are just polluting this thread.

I know a couple of guys......... I'll send one of them a text right now.
To confirm - you have a 2020............
(this is the sort of guy who either knows, or will ask to find information - if he comes up with nothing, then there's nothing in our area at least.)

IF you don't care about the warranty aspect and plan to do the work yourself or by independent shop you can take a chance with these:
https://www.melling.com/4-4-25-new-camshaft-for-chrysler-3-6l-dohc-left-intake-mc1442/

Jegs has then in stock it appears.
https://www.jegs.com/i/Melling/689/...pcK6UjKqAObi78lVmH5GsqxUbgmXv3DiuedZy3ytJKxKZ

Please triple check everything before you order to cover your own ass.

As far as I know, no one has ordered them so the quality and accuracy to OEM is unknown, only thing to go off of is their name for what that is worth.

also do some measuring and comparisons to your OEM to make sure they are the same.

Text just sent. He didn't respond to my one from earlier but he may be off or something today....... but I'll be SEEING him the first of next week if I don't hear from him later.
If they have one, or he can find one, I'll grab it. (not for me, I don't need it! (he says as he knocks on wood......))

EDIT - no wonder he didn't respond to my question about accessories for mine - he's out until tomorrow but just responded that he'll check for me.
(Frankly, if he can find any - I might just buy them and pass them at my cost to those here seeking them. This is silly and painful and frustrating as hell for a lot of people)

Thank you you for checking. I even just got off the phone with Scott Story, the Mopar guy in the backorder message on the Mopar website, they're waiting on a bunch still too for months.

At this point I realize I'm just getting in line with a bunch of other 3.6L owners. All I can hope is that Jeep will focus on at least solving the supply chain issues, if not make it right to us as well.

 

[Glad Newbie]

The back and forth pissing match aside, Shadowspapa's suggestion about dealer shopping is spot on. I had the same issue last summer. I was able to find a couple dealers with the parts. They wouldn't sell to me, but enough bitching to my dealer and Jeep Cares got me my parts. Good Luck.

There is also another place to checkbI am told has them in stock quite often.
Frasier's . I know a fuy that just bought one about a month ago.

I am now in need of another camshaft. Just had an intake cam replaced April 2024 and now I think its the same one... Can't find any on Mopar other than the "kits" which are double the price and don't clarify what is included.

I can check pricing and availability of the solely the Cam but I need to know which one you are in need of.

Thanks,
- Benny

 

[ShadowsPapa]

Well, crap............ struck out. They don't ever stock that part because they haven't seen a need for it, but they also can't find any.


Got a text this AM - I can get my accessories from them for decent enough price, but the cam is something they don't see fail so don't have any or a handle on getting any.

 

[Skullivan]

Well I found out which one it was late last night... Drivers side intake cam. Do you call this one the Left Intake Camshaft? (Drivers perspective).
