Major oil leak from the rear passenger side

I guess I'll get it and find out!  I'll post back what I actually get and if it all fits.  It does say it is guaranteed to fit so if it doesn't, pretty sure I can return it, I am on first name basis with the local NAPA crew!

No problem, 3 is far superior to 0!

I am a little confused, the Napa online catalog show this as being 5 gaskets?  Sounds like you believe this items is only 1 gasket not 5?  Am I missing something?

Yeah that's the fel pro kit that people often say is missing a gasket of a particular size, so I'm playing it super safe by just buying the exact gaskets I need by the SAE size. Some people say it works OK but FWIW I only see 91+ people saying it works on the reviews. Every Renix person that left a review said that it was missing something.

 

Edit (again): When I clicked on the link ,I was on my phone and thought that the kit you linked was the singular large gasket ES70301 and not the full 5 piece kit, so that's my mistake

Sorry didn't see this, it was on the second page of the thread. Good luck to you! I would've taken the chance but with this being my daily I couldn't risk leaving my truck out of commission for more than a day.

Has anyone had experience with doing away with the oil filter adapter housing in its entirety? This would allow you to eliminate the issues with the adapter gaskets leaking. I've read a few things about just putting that nipple that the oil filter mounts onto directly onto the block and the oil filter fits perfectly on the machined surface. Does this reliably work? any downsides? Why would AMC put an adapter housing if it could very easily run without one?

 

Here is one of the threads I found:

Depending on what's in the way and the size of the filter, you may not have room for it on the side of the block.  It may hit what is in the engine bay.  The filters aren't exactly short.

 

And, with it on the side of the block, you get oil dripping down the side that you have to clean up.  Of course, you have to deal with whatever is under the filter getting dripped on anyway (usually the axle).

The thread I linked mentions a specific non-stock Bosch filter that is supposedly the correct size to screw on and not have clearance issues.

 

How come oil would drip down the side of the block? Because the mating surface isn't meant for the filter?

I should have said that applies when doing a filter change.  Being up on the block, oil will run down the side as soon as you start to pull the filter.

Ah ok, I thought you meant it would just leak in general lol. That is true but it would be nice not to have to worry about the adapter seals going out. Although at almost 190,000 miles, I would probably never need to put in a new set of O-rings again lol

Yeah, given a once in 200K maintenance on the adapter O-rings, I'll keep the adapter.  I'd throw that in with a rear main seal, oil pan gasket, and valve cover gasket on a Saturday.

Thanks for the help
