Replacing Aftermarket Oil Filter Adapter with OEM
On my 1998 Cherokee (6 cyl), I noticed an oil leak originating from the filter adapter, but it appears that the adapter on my Jeep is an aftermarket part. I just bought my Jeep a couple of months ago, and it is time for the first oil change. I noticed that the currently installed filter is a long, skinny guy. The replacement filter I bought is shorter and has a larger diameter.
I would like to replace the aftermarket filter adapter with a Mopar one. My motive for doing this is so I can use the OEM size oil filter. I believe that I need the following parts, but would anyone mind chiming in if I am forgetting something? Oil Filter Adapter - Mopar No. 53020080 Adapter Bolt - Mopar No. 53020237 O-ring Kit - Crown No. 4720363 For a cheaper option, I suppose it would do me well to pull one off an old Cherokee at a junk yard and just get the o-ring kit. Thanks in advance for the thoughts. |
Yessir, you've got it right. That's all you'll need.

What makes you think the oil filter adaptor is aftermarket?
The long skinny filter? The short, fatter oil filter has a much smaller gasket diameter than the diameter of the filter case itself. A skinny filter will fit on the OEM adaptor. You might just need an o-ring kit, and the correct filter. |

You might just need an o-ring kit, and the correct filter. Are the gasket diameters of these two filters "close enough" to use them interchangeably on an OEM filter adapter? I would love it if I could just buy an o-ring kit. I should really get in there, clean the gunk off the current adapter, and see if I can tell whether it is an OEM adapter or not. |
I'd go with a 3/4-16 adapter for your filter. Alot more options for filters, plus you can use an oversize filter such as the Motorcraft FL1A.

He should already have a 3/4-16 thread adapter. He's got a '98 XJ. jchens, More than likely, you have the factory adapter and someone put a skinny filter on it at some point. If it is leaking from the O-rings, just get an o-ring kit and re-seal it. Get yourself the proper filter, or an even larger one. (like a 51515) A bunch of people use them. |

I'll probably do that the next time around since I've already got the stock filter on hand. |
Wix 51085 is the standard filter and the Wix 51515 is the oversize. It is possible that someone thought they had the correct oversize with the 51516?
