New Jeep 2.0T Hurricane 4 has complex tech [Engineering Explained]

[alphawolff]

I said that the SOCKET wouldn’t fit.
I guess you could screw the small ones into the larger holes but good friggen luck screwing the others in. Maybe You could do it, that is then the reason for the caution.
Do you own any calipers or a micrometer?
Do you have a 16mm and a 14mm deep socket?
If so, measure the diameter of each, chances are the 16 is bigger than the 14.
Do you think that the spark plugs are just sitting on top of the cylinder head?
My money says that they are down inside a bore that is just large enough for the Socket to go in.
Rocket science, not really.

"Weird, the 14mm fits in both holes. I wonder if they just gave me the wrong plugs? Need another 4 to finish this job I guess"

Then why are there 6 “nubs” around the pre-chamber holes? I’m waiting…

If you can’t stay off Tic Tok long enough to tell the difference between a smaller spark plug with a Blue stripe that fits a smaller socket then leave the job to someone else.
If only other repairs on new engines were this simple.

We had about a dozen brand new Ecotech cylinder heads that had been disassembled and machined for cylinder pressure transducers. The tech that disassembled the heads not only threw all the valves in one box he also put all the camshaft retaining caps in a box together. These are line bored after being torqued down on the specific head and have No identification numbers. We ended up with a big pile of useless heads because you would have had to deal with measuring each cap on each saddle, it would have taken forever.
My point is, maybe sometimes it’s better to leave it to a professional that’s trained to handle the job.
People are going to spend $50,000-$70,000 on a new JEEP and half ass a plug change? Do you even know what the interval is for plug replacement on the new EVO?
Good thing we got rid of distributors and all those confusing plug wires. Hell, most all new engines that I know of have wiring harness that could be installed properly with your eyes closed because the connectors only fit specific sensors etc. Shop manuals especially for new stuff are critical for proper repairs and servicing. That and reading them.

How long before this engine is out in large numbers and will be needing plug replacement ? The same geniuses that can’t get an oil change right, and in my case not tighten lug nuts ruining a wheel won’t f’ this up ? Should we start a poll for how long before you can post “I told you so” ?

Critical thinking, are people incapable of this anymore?
Could these same people have even had a chance at rebuilding a carburetor?

Perhaps cynical, but f’ ups happen and the possibility should be reduced AMAP. Perhaps the needed plugs aren’t available as impossible to put in the wrong hole. But should have been used if they are.

If it’s a dealer, there are no excuses even though they can’t master an oil change. For ShadeTree’s, it should be personal responsibility to recognize you are out of your depth. Sink plumbing seems easy, but a DIY’er can make it look like some ornate hamster tube competition.

From the company with such a stellar reliability record and great customer support and service. How can this possibly go wrong?

Aside from my Toyota yaris commuter car, Jeeps have been my most reliable and dependable vehicles. 200k+ miles on a few XJs with the 4.0L, a ZJ with the same, a TJ rubicon with the same, and a WJ with the 4.7L v8. Our JLURs were both trouble free. The 1st stolen at 63k miles and the current at 55k. My JT is at 45k trouble free. Fords have been the last reliable and the only ones with major problems before 100k.

Absolutely right about the dealers and oil changes. Let’s face it, it’s the lowest paid tech in the shop that does them.
I bought my 18 JL with 38,000 on it. Very good documentation of all the maintenance done.
When I did my first oil change on it I had to use a 1/2” breaker bar on the drain plug, you could see the pan flexing before it broke loose. The rubber gasket was almost completely rolled around the flange on the drain plug.
Good help can be hard to find and if you do find good help treat them well.

Am I the only one that thinks that the 6 Nubs on the cam cover gasket were intentionally designed to limit use of the wrong tool?
How do you prevent someone from forcing the larger plug socket past them.
What’s the saying “you can’t fix stupid “

Agree- Dad had a truck service, good employees were hard to find. The stupid ones mistakes cost him time, money and grief. You don’t really know when hiring, the first (and last) thing one genius did was fuel a big rig with a couple hundred gallons of premium. Grief, time, and money. …. Cynical can be learned.

Honestly, I question how many current 2.0T’s have had issues after a botched plug change.
Compared to an Ecotech or Ecoboost it’s a little more involved.
And you’re right, I wouldn’t bet my left gonad that the new engine won’t run into problems.
It’s up to the owner to do their due diligence to try and avoid such problems.
I know this much, I won’t be getting one anytime soon. Not when I can get a turn key 5.7 transplant for somewhere in the 30’s.

The dealer had my GC Friday, fixed, uhh nope, going back Monday to try again.
We put our best men on the job

It seems like all of the electrical connectors are unique so you can’t screw up the electronics when disassembling/reassembling. It makes no sense that they don’t do the same for the mechanicals…

Aww, don’t sweat the 6 nubs, heck, a thin wall deep socket works Just F’ing Dandy. ….
We had to use a hole saw on the fender wells and a conglomeration of socket, swivels, extensions, to change the plugs on a friend’s 68 BB Mustang. ….. the manual, step one
•“Pull Engine”. We had a better idea.
