3.6 Pentastar purge valve/misfire issues

There's two different possibilities from what I gather watching YouTube. Either the camshaft lobes wear out by themselves, or the needle bearings fall out of the cam followers consequently wiping out the cam lobes. This has been going on for years and years.
In either case, oil probably isn't a fix.
 
That's typical for a Chrysler Pentastar V6. Their camshafts are always wearing out and the needle bearings in the cam followers fall out.

The engine has four camshafts that are about $300 a piece just for the cost of each camshaft themselves.
Not sure where you're getting that price? My cost as a shop is $390 - customer cost will generally be a fair bit higher.
 
Are you having them replace all the followers or just the ones for 1,3,5?
Doing just the bank 1 intake cam and lifters/followers. The original pentastar seemed to have more randomized issues but the PUG version like this wears out the bank 1 intake cam a lot harder than the others.
 
I think @wwillson did all of his when he had a rocker fail. I'd advise the OP do the same. What's impressive is that this failure generally doesn't damage the engine, making it an annoying, but relatively low cost fix.

Yes, I replaced all of the followers. One was clearly bad and another had hints of being slightly loose. I didn't want to tear into the engine twice for the same issue. I did all the work and didn't have to replace any cams. I believe my total cost for parts, which included followers, lifters, and gaskets was around $400. Don't bother replacing the lifters (slack adjusters) unless you visually see something wrong with them. There is nothing to them, just a solid piston with a leak.

I know it's not an apples to apples comparison, but I found this on a 2015 Wrangler. Btw this was taken in August last year but he kept driving it - I'm just now getting to put an engine in it. The thing that stopped him was timing chain death noises and low oil pressure 🤣

Think that's well past the "generally doesn't damage the engine" threshold :ROFLMAO:
Yeah, that goes into the "driver needs hearing aids" or "driver has no concept that a banging sound from the engine compartment needs to be addressed" bucket. Simple rule, the more it bangs, the more it costs to fix.
 
Woah! Did you replace that camshaft? Or did he just let that one rip?
The back story is that he is rural postal driver and he bought this Jeep for his route. It was already well used and had just had some work done to it but as soon as he picked it up, he got an engine light (I don't remember the code anymore). When he brought it to me it was already a bit talkative and I warned him that it probably had valvetrain issues. Well he didn't have the time or the money for me to look at it. Finally after some months, he brought it in and I tore into it and found the carnage that you see in the pics. Well now with the high cost of repair (chains/guides/cams and so on) and the fact that it already had a pile of miles (220k) it was decided that an engine was the best course of repair. Since he didn't have the pile of money for the engine, let alone the repair, he said put er back together and I'll keep driving it until I've got the money to get this done. And drive he did. For several months, almost every day on his mail routes (he's a sub) until the oil light came on. A change of oil and filter temporarily remedied that. Along the way he lost cyl 5 to a bad injector (which I replaced) and then 5 again, this time because the cam or follower finally gave up the ghost. I unplugged the injector and sent him back out on his way 😂, but a couple months later the oil light came back on and the timing chains started banging around in there like they were tired of being inside the engine finally ending this poor little motor's time on the road.
 
I look forward to tearing into my early 2012 when it finally comes time. 178k and other than the 62te which is a different story, seemingly no issues with the 3.6

Rain, snow, sleet, hail, or the Pentastar tick won't stop the US Mail. LOL
