New Motor ?

[Tlake]

Hey ,
I have a 2016 3.6 Pentastar motor with 94000. we had a misfire cylinder 3 and the dreaded tick. My buddy who has done plenty of these at work opened her up replaced one cam and all the rockers n lifters/ fuel injectors/ plugs/PCV Valve. She ran great for about 3 weeks, then a cam position sensor code P0369(replaced) and now another misfire 3. Its now opened again , new rockers look ok. He wants to replace the three coils and plugs on that bank 1,3,5. Should we do a compression test?
Any suggestions? Thanks

This forum is for the new (2018-Present)Jeeps..while they share the same motor, they are different. In saying that, there are a lot of JK guys here that might be able to help.

Also, unless you have a 4XE your Jeep does not have a motor. If you have the 3.6l fron 2016 you have an internal combustion engine. A motor runs off an external power source, say a battery like a 4EX. Your 3.6l generates it's own power. Sorry, that has always been a pet peeve of mine...

Sorry for the lack of an answer to your question. Don't know if the JK folks would have a better answer.

That said: YES do a full compression test.

Then I would want to know why after spending your $ it failed again with how many miles on it???

Don' want to say your Buddy is a bad wrench, but why did it fail and fail in the same place (it appears). I have built a lot of engines, NO, MOTORS, transmissions and axles over my racing and off road days. I had a shop fo r9 years and never had a come back. I gave a warranty for any Jeep mods I make: If it fails due to my mistake, I will come get you off the trail if local, if not local I will pay to have you extracted adn brought back to my shop.

Never in 9 years did any one ever call.

What was done to your jeep falls into either either a bad components was in teh new install or ???

Do the compression test, check the ouput on the coil and replace the cam sensor to confirm good or bad...

Hope it work out for ya!

@Tlake If memory servers me right. FCA had a recall on those 3.6 Pentastar engines with those symptoms. My co-worker had the same issue and was able to have the dealership do an "out of warrantee repair" at almost no cost to him other than sparkplugs, oils and antifreeze. Hope this helps.

Thanks for the help! I see I’m in the wrong place. Sorry for that.
my buddy came right back opened her up a second time (no charge) cams are smooth and new rockers looked good so now a compression test and 3 new ignition coils .

I would not spend money speculating on the coils, swap them from the other side of the engine. If the problem follows to the other side then its a coil problem. If the problem stays on that side then you saved $$ not buying unneeded parts.

I agree

The 4XE has a 2.0T ICE, as well as the electric motors, as it is a HYBRID vehicle, not full electric. The ICE is also a “motor.”

Maybe you should tell that to the engineers and all the other millions of car guys. Most car guys I have heard call electric cars toasters I guess that’s their pet peeve.

That could also apply to some ICE Jeeps with manual transmissions.
