  1. CEL for Spark Knock AND P0300 fix

    The shade…. But thanks for yet another 5000 word essay. If the caught result remained constant, my can would be catching ~20 ounces every 5000 miles. That’s significant, especially on a new motor.
  2. CEL for Spark Knock AND P0300 fix

    They may work, but not all the time, hence the TSB’s and new part numbers. Rudimentary yes, but more effective than the factory installed parts… also yes. I’m getting about 1.5 ounces of oil per 500 miles in my catch. Dealer just replaced the PCV, so will see if that helps.
  3. CEL for Spark Knock AND P0300 fix

    As to the quality of the information im getting, I hope its been made obvious, that some things are logical and good to go, while others made my neck hair stand up, and I got to dig. When it comes to digging, Its not unilateral question asking. It's concerning that they wont give a copy of the...
  4. CEL for Spark Knock AND P0300 fix

    thats the whole point sir... is that Mopar is directing them to do this... hence why im perfectly fine with my band aid, and a new PCV when the parts arrive. very rarely will you get a better head seal than the factory one, and im not ready to let them do this.
  5. CEL for Spark Knock AND P0300 fix

    Any insight on if there was an engine change made in 2018? Did they redesign stuff in the 3.6? It will be VERY bad for them, if this turns into an EVERYBODY type of situation. Would it make any level of sense to maybe shove a borescope in the spark plug hole and visually inspect the piston...
  6. CEL for Spark Knock AND P0300 fix

    Couldn't agree more! There has to be more to this. Today I spoke with Mopar, Jeep, and the Dealer... Jeep and Mopar both said "the bulletins are sent to dealerships and we dont have anything to do with it." I eventually got frustrated and called the dealer back, and asked for a copy of the TSB...
  7. CEL for Spark Knock AND P0300 fix

    True and correct on all of that. What's wrong with the PCV?? Who knows, it's Jeep... probably something simple and stupidly overlooked during design. According to my local Jeep shop, there is a new part number for the PCV, but theyre already back ordered until like January or something. Im...

  9. CEL for Spark Knock AND P0300 fix

    Correct about the band aid. I have <7000 on my Jeep, and after speaking with the cranky, angry, older guy who has worked on Jeeps for like 40 years... I decided to go the Catch Can route, and a little dose of sea foam. Seems to be doing great. I'll update when I actually have to empty the can.
  10. CEL for Spark Knock AND P0300 fix

    Spending WAAYY more time "talking" with Mopar... Mopar says, contact the dealer, and the Dealer says Contact Mopar for more info. Nobody seems to be willing to release an official copy of the TSB. Im glad I at least got to take a pic of it last time I was in there.
  11. CEL for Spark Knock AND P0300 fix

    I mean, i put the TSB number in the original post. **EDIT** I had to shrink the pic here, it was too large. I got this at my local Jeep store.
  12. CEL for Spark Knock AND P0300 fix

    not sure why in the first place, but it is a thing. They seem to have a LOT of vacuum at idle, and mine threw the codes while navigating a parking lot. Never while under actual driving load. They have revised the PCV itself (new part number), but of course they’re back ordered.
  13. CEL for Spark Knock AND P0300 fix

    Not sure this will work for EVERY Gladiator out there on the road, but I did a thing. Some of you awesome folks made it known about the new TSB-09-012-22 for spark knock/engine symptoms... For any who havent seen it, it involves pulling the heads, cleaning the piston head, and the heads to...
  14. Where is the instant MPG display setting?

    Mine just did this the other day. Probably 6-10 restarts, reset the EVIC stuff to default, and like most, nothing brought the current MPG back. I did have luck after I changed the stuff in the "Favorites" menu for the EVIC. I disabled the fuel economy one, then its just not there at all when...
