Rear Main Leak?

[Tncdrew]

The aftermarket aluminum oil filter housings are terrible.

Do they end up leaking like the OEM?

I need the experience and help of the jeep community to tell me if what I’m seeing is a rear main seal leak or not. At the same time I did notice that it appears that my oil filter housing may be leaking as well. Not sure if it related. Anyone seen anything similar to this?

Just found this when I changed the oil on mine yesterday. After paying 3k redoing the right cams and lifters, I’m hoping it’s not the RMS.

*Sigh* There has to be a lot of people of there who have no clue their RMS is starting to fail. If I know Jeep, and if there will ever be a recall, they will just say it's covered with vehicles under 30k miles.

The thing is, there is no oil staining on my driveway to indicate a leak. I guess it is time to look up what I have to do to replace the seal.

Some times it only leaks under pressure or while moving so you will see oil but no drops on the driveway.

I didn’t have any problems with the Dorman housing. I bought my own felpro gaskets and did not use the supplied ones. Also the dorman housing doesn’t come with the sensors. They will not come out of the stock one, so buy that as well.

Pull out those plugs on the bottom of the bell housing and if you are good look up into there to see if you can find the leak. Best is to use a cheap borescope. Then you can see on the back of the flywheel/flexplate if it's from there.

If it's the oil filter housing, a flashlight and a gander down in the V of the engine will determine if that's what the problem is. It's not a 5 second analyses but take your time and you'll see. I will tell you this, looking at it from the bottom like this is a guessing game (as you can see by the responses).

Plus, that is nothing of a leak. I bet it would take a few years for it do become actually wet.

pull the two rubber inspection plugs and look up and see if you can see the oil line from the RMS this def looks like the rear main. I had mine replaced at like 1500 miles

Yes, and rather quickly.
