68661147AA - Right Side Intake Camshaft

[yoda13]

These things on back order still? I’m wondering what I’m looking at when mine goes into the shop.

I had my right side intake camshaft (and rockers) replaced under warranty by the dealer in July. The jeep was in the shop for a week. I guess I got lucky.

They have been on and off, We currently have stock with their being almost 2k backorders on Mopar's side. If you're interested let me know as we have codes.

This says there are 6 in stock.

I'm able to tear into mine also. 94k mi, misfire on 5 under hard acceleration, and it sounds like a playing card in a bike spoke on the pass side.

Thank you… Now I know how to properly explain what my engine sounds like with only 35k miles…

I am trying to order part # 68661147aa but the dealer is saying it is not a match for my VIN.

I think its because the parts database maybe isn't quite correct and it wants to suggest the cam by itself as the correct part as opposed to the cam kit.

Any thoughts on if this part # (cam kit) is the correct one for a 2021 Sport S?

Thanks!

It was the right one for my 2020 Rubi. I'd have a hard time believing there was a difference between the two.

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 am not in anyway diminishing your treatment and the lack of availability of parts. This is just an idle question that likely is cheaper than a $35K engine swap. Are there not any makers of aftermarket camshafts?

No there are no aftermarket makers of Camshafts thats been asked 1000 times.

Check with Benny here. Allmoparparts dot com. He's a sponsor and a great guy, too

I wonder how many know that MOPAR stands for MOtorPARts

Well I sent an RFQ through the website you linked me too. Not looking good though for people needing intake camshafts. I just talked to my dealership parts guy (we used to work together a few years ago and he wouldn't bullshit me), 1,200 intake-driver camshafts on backorder and 12,000 intake-passenger camshafts on backorder! Apparently the running theory is that the oil lift tubes that carry oil to the cams were designed too small and when your oil gets further in it's life it is harder (more viscous) for it to travel up there.

Maybe more frequent oil changes are the solution? Maybe higher pressure pump? Seems impossible to "modify" the size of the passage for the oil.

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.

Biggest challenge for sure will be to source the parts in a reasonable amount of time...

Making those passages larger isn't out of the realm of possibilities but it would require a complete tear down of the motor . It would be a monumental job for a DIY . But I have seen videos of this very thing being done on an older V8 block on YT.

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.

There will be a flurry of chatter here now because a popular Jeep youtuber has posted his challenges about acquiring intake cams on a short schedule, which i am sure will rile the masses. By his account there are 12,000 backorders for them.

This was a interesting thread.

Do you mind sharing a link to that YouTuber's page or video?

EDIT: I see it's the #1 trending post right now

1,200 intake-passenger camshafts on backorder and 12,000 intake-driver camshafts on backorder!

LOL - nothing to do with failure rate. Look around - do you see forums flooded with bank 2 cam failures? No.
But people will read into things whatever they want to support their ideas, a confirmation they were right all along, no matter how wrong.

Maybe more frequent oil changes are the solution? Maybe higher pressure pump? Seems impossible to "modify" the size of the passage for the oil.

More LOL - pressure has NOTHING AT ALL to do with anything and anyone who has worked on hundreds of engines over many years would laugh at the idea. An idling SBC - IDLE, mind you - with a pump half the size and capability of these can supply 8 cylinders and shoot oil clear over the fenders at idle, at about 20 psi and we run 30 psi until 3,000 RPM then shoot up over 70 psi.
The typical rule over the years has been 10 psi for every 1,000 RPM. Yes, that's correct, even for 8 cylinders. So for 2,000 that's 20 psi, 3,000 it's 30, and we run 30 at IDLE up to 3,000 where it kicks up to high volume mode and kicks the pressure up over 70.

Apparently the running theory is that the oil lift tubes that carry oil to the cams were designed too small and when your oil gets further in it's life it is harder (more viscous) for it to travel up there.

WTH? Right, running theory - there's the internet and guessers for you.
The exhaust side LASH ADJUSTERS oil the cam lobes. There's no "oil lift tubes".

Worse about that BS is that oil THINS as it ages, not thickens. It loses viscosity. Go check with the oil lab tests posted around these forums.

Sorry, you are listening to crap - maybe he wouldn't bullshit you, but if he doesn't know he's talking bullshit.................

There's just so very much wrong with the hole post, every single bit, theories and all.

This is why people get so confused, it's all speculation from people looking for simple answers or to VALIDATE their own thinking.
