New Mojave - Multiple leaks

[bleda2002]

Doesn't look like multiple leaks looks like a rear main that's just blowing everywhere while you drive. I've had 3 of them, dealer usually fixes it in 2 days.

As for coolant every single new jeep jl or jt I've worked on (5 total) has the coolant low after a few miles from burling bubbles, quick top off has sent them all on their trouble free way.

My 2019 JL 3.6 with 65K, 2023 JT Diesel with 27K. Not a single leak from either. Hell, the only thing leaking from my 2000 TJ is the rear main, which those 4.0 are notorious for.
With only 2K, I would absolutely be taking it to the dealer.

I've had 7 vehicles with 4.0. Still have one in my car.
Never a rear main.
They did have pan seal leaks, often mistaken for rear main, but I've never seen one with a rear main leak.

The Jeep I bought from Dad's estate had been worked on for an oil leak - the dealership changed the pan gasket.

So my thinking is, since I've owned over half a dozen, and never seen a real rear main leak, and the only ones I've seen with oil leaks happened to be the pan seal............
(the 4.0 in my SX4 was tough to seal around the front of the pan)

Otherwise, why the 4.0 more than any other engine that uses the same type of seal?

(It's the same seal used in the 258 for many years, and I've had several of those, too - so between the 258 and 4.0, using the same rear main, that's over 10 that I've had)

Brand new Mojave X less than 2K on the clock. Was installing mud flaps yesterday and noticed multiple oil leaks. Rear main seal, trans pan, and other fittings hookup points on parts that I don't know what they are. And the coolant level is low so it's probably leaking coolant as well. Didn't see any leaks at the oil filter housing up top. All below. Made in America. Sheesh

The oil on the side of motor above trans is motor oil. Hurry get it i there before it blows
Just kidding .
Pull those inspection plugs shine a light in there see if oil is in there .

Funny thing is, looking at these pictures and looking at the pictures I have of my wife's JLU transmission leak - this looks a lot like that fluid, except for the bottom picture.

If it isn't leaking you aren't using it! My transfer case always has fluid on it.

No reason for that, or to accept it. They should not leak, especially in the first 60,000 miles.
If it has fluid on it, it's got a leak.
I've had transfer cases with over 100,000 miles on them - NO leaks.

Odd that people accept if or believe it's some right of passage or if it doesn't leak, it's not being used. Doesn't matter - it should not leak.
If I see seepage or a leak, I fix it. It means there's a flaw, or, it's not venting properly or similar reason.

I have a drawer of drain plug seals of various types. I even put new spark plug gaskets on those plugs that required them after pulling, cleaning and re-gapping them.
I keep teflon tape around, use new aluminum, copper or nylon gaskets where or when needed.
Some just don't care - I don't like the mess that can be corrected.
