What does this mean and what would it look like?oil pan seal rolled over
I've always thought this myself, which is why I've used Fel Pro on more than a dozen at this point. I'm willing to give the Mopar one a try though.What does this mean and what would it look like?
Almost every other place I’ve read about the RMS has recommended fel pro as a seemingly gold standard.
I've wondered if they are the OEM supplier for Jeep, since they're part of the Dana Corporation. When you read the description, and see the website, it kind of looks that way:With very little testing, I had no leaks on a victor reinz (Dana Spicer branch) OPG, then I had a leak with the Fel Pro, and then no leaks with another Victor Reinz. Not sure if I effed up the Fel Pro but I can’t help but wonder if Victor reinz is maybe the better option. Or maybe Mopar. I do like the lineup studs Fel pro gives you so I kept those from the FP kit and used them on the second reinz gasket.
Yeah not sure either, I wondered the same thing. I do recall that both RMS and OPG had “improved design” in their description. Not sure if that’s boilerplate or true. My previous RMS and OPG for 6 years was Fel Pro and I don’t know what came out when the FP went in (2014), so not much to compare to.I've wondered if they are the OEM supplier for Jeep, since they're part of the Dana Corporation.

"With Victor Reinz gaskets, you can be sure you are getting sealing solutions that deliver OE quality gasket technology and engineering. That is because Victor Reinz is an original equipment supplier and the trusted choice of manufacturers the world over, offering broad coverage for foreign and domestic cars and trucks. In Victor Reinz gasket sets, you get the right combination of components needed for fast, long-lasting repairs."
This is interesting. He does have over 200K on the engine. Now I'm wondering if it might be a good idea to install a new set of standard main bearings? They looked fine when I pulled them, but I didn't verify clearances.My engine machinist told me once that the reason some engines have more problems with rear mains is due to the main bearing clearance. From what I understand if the rear main bearing has more clearance it will "flood" the seal with more oil than normal causing it to leak. He said the fix was to install a lower clearance bearing on the main to slow that flow down.
If it still leaks, check your thrust bearings for play on the crank. If there's a groove worn in the crank it will leak intermittently when the crank shifts enough to let the oil through that groove.I've done many rear main seals, without issues. However, I now have one on a friends vehicle that is being obstinate. I've helped him replace it twice and it still leaks ever so slightly. I know it was installed correctly and I didn't feel any groove worn in the crank. Any suggestions on what to do next? I really wish there was some sort of option that had two sealing lips and not one!
I should've taken a picture of it, but basically what happens is right along the back side of the oil pan where it curves around the crank there isn't much supporting the pan gasket, it can shift and fold over a little bit towards the inside of the pan which makes it not sit flush against the sealing area like it is supposed to. Mine actually didn't leak initially, but started to about a day or so later.What does this mean and what would it look like?
Interesting discussion… I replaced mine using all fel pro stuff and immediately had a worse leak than before. I still think it’s because of installation error, but I may try the mopar RMS this time. Almost every other place I’ve read about the RMS has recommended fel pro as a seemingly gold standard.
I had my buddy buy a Mopar RMS. If that doesn't work, I'm tapping out!Not an answer, but if it makes you feel any better the previous owner had the rms replaced just before I bought it from him. It still leaked. Being the expert mechanic I think I am I replaced it again. It still leaks. There’s no wear ring on the crank, so like you I’m stumped how to stop the leak. Being anal about leaks, I’ll probably be back in there this winter to try again. It’s just a drip and maybe a quart low at the 5000 mile oil change so no big deal, just my head trip.
I hate to break it to you, but the Mopar RMS is notorious for leaking
The joke being that the original seal that came in the vehicle is notorious for leaking? Or do you mean that people have problems after replacing the seal with a Mopar?
