Jeep Wrangler JK Owners READ This

What caused the mechanism to spring mechanism to fail? Can the dealer tell you why?

I went back and re-read and he's claiming this is on a 2015??? It sounds like a 2011-2013 since the 2015 no longer has the spring under the cap, unless I'm missing something entirely. Still smells fishy....


I call foul- that dealer's trying to get away with something.

FWIW, its the bypass valve that they're talking about, and is apparently the reason that they changed the Pentastar cartridge oil filter for the 2014 model year. It doesn't block anything, it just lets oil bypass so it should NOT have been responsible for an engine failure. Short life, maybe, but outright failure?

About four months ago my sisters 2013 Jeep Liberty's transmission decided to take a dump at 56,000 miles. Jeep refused to cover it claiming she never brought her jeep in for vehicle inspection! I told her to get a lawyer but she decided to trade the truck in. Since then I have talked to several people who had the same thing happen one owner only had 46,000 miles at failure and Jeep said no way no coverage! Total [censored]!

Hmmm...

Lotta fanboys on that thread.

Also there are pictures posted here and on that thread, by posters whose stated locations are different so someone is a picture thief too.

Best advice on that thread is to demand the decision in writing.

Not true they can't force you to buy only their filter... Is this in P.A. ??

Call a Lemon Law Attorney try Kimmel and silverman and make sure you have all the documentation they are free to the consumer and 100% amazing.
No more talks with the stealer or the manufacturer.. K+S makes it easy look at their website they are the best.

I watched the video. This assembly is a joke. It's designed to fail and on top of that, if the bypass valve fails you have to replace the whole oil filter/cooler assembly. This kind of design work would scare me off from ever owning a Jeep or Chrysler vehicle.

^^^ I was also thinking the same thing about how bad the bypass valve design was when watching that video. It sounds like a pretty common failure.

Its obviously the reason they changed filter housing designs after 3 years(actually I think they changed vendors for the filter/cooler housing). But the "failure" isn't a failure unless you lose the valve or the spring. Just pop it back in place and re-assemble. The filter cartridge retains the whole assembly once the cap is screwed on. Its become a standard part of my routine when changing the filter on my wife's Pentastar to verify that the bypass is in place and sealed against the filter cartridge with spring pressure before screwing the cap on. Takes 10 extra seconds, and mine hasn't ever actually popped out (yet).

That old Jeep designed I6 in the TJ Wrangler looks awfully good compared to this.

Those engines run forever.

Funny, you get just as many people saying "4.0's break piston skirts and crack cylinder heads."

I own both, They're both good. The old 4.0 would have a very hard time keeping up with traffic in a modern JK since its quite a bit heavier than the old TJ, YJ, and especially XJ, though it would do offroad crawling just fine.

The current long wheelbase Jeeps should be using the Dodge EcoDiesel as a powerplant.

But Jeeps have needed diesel power for a long time.

Imagine the old TJ with a nice 2.0L 4 cyl. diesel similar to the one in the Chevy Cruze.

A whole lot of Jeep guys were into Cummins 4BT swaps back when I hung out on the Jeep forums- and that was into XJs, YJs and TJs, not even considering the JKs. The Pentastar is flexible enough to do the job well, but I agree that something like the Ecodiesel would make a nice option- especially since its already available in the WKII. Gonna be a good bit heavier (total installation, including intercoolers, plumbing, aftertreatment, etc.) than the Pentastar. Maybe its simply a size constraint under the hood of the JKs.
