If I am putting an ax15 from a 94 in my 89 MJ would I use the clutch components from 89 spec or 94? I imagine 94...but I just really want to know make sure!

Did the 89 have the AX-15 too or BA10/5?
There's something funny to do with the pilot bushing going between the Peugot and Aisin-Warner boxes. As far as I'm aware there's nothing to be concerned about between different year AX-15s unless you have the obvious internal/external slave difference (which I thought was 1995, but could be wrong)

The ax15 going on has the external slave so obviously that part coming from then newr ax15. Just wasn't sure if everything else remained the same! I currently have an ax15 in the 89...2wd...you can see where I am going with this.

I had the issue with the deteriorated line inside the tank, could hear the tank all day when cranking but had no pressure. Replaced the rubber hose and it worked fine.

Try taking the fuel line coming from the tank to the filter and put it into a cup or water bottle. Have someone prime and crank the engine while you watch the bottle. If it build pressure and you dont have a blockage in the tank the bottle will have fuel in it. If you know for a fact there is fuel and that you are not getting any fuel the rubber hose inside the tank that goes from the pump to the "fuel out" line may be deteriorated and need to be replaced.

Also check the CCV system for cleanliness. Crankcase vapors are stinky when directly vented.

Lol, set myself up for that. Could it possibly be the converter though? Someone told me it could but I didn't see how.
Hello all,
Long time lurker, first time poster. Well I bought a '97 XJ not to long ago and decided change the oil in it as I have no idea how long it had been since last changed.
Before I changed the oil, I had ZERO oil leaks, not the case since I have changed the oil.
Just so you all know I put Valvoline MaxLife 10W-40 since the engine has about 155K miles on it.
So I have chased the leak down and researched it, and I unplugged the oil pressure sender before getting the filter out, and I might have caused this leak. I know this is a common problem with the cheap plastic senders. BUT, looking at it closer, it appears to be coming from the bottom of the adapter that the sender screws into. (See pic with item circled in red. That is what I am calling the "adapter") This is NOT my vehicle, just a picture I found for a cleared view.
So, my question, is part replaceable? If so, what the heck is it called? Please look at the picture with the plastic sender, this is my vehicle, and you can see the sender isn't wet, but the block under the adapter is. I am wanting to replace it because looking at the sender unit, it appears to only be screwed in a few threads, and I am assuming that a prior owner has cross threaded it, and last thing I want is to be headed down the road and have those threads fail at 65 MPH!
Sorry for being long winded, just trying to give as much info up front. Thank you in advance for your help all.

Remove the sender. Remove the fitting. Both have tapered pipe threads. Seal the fitting threads with #2 Permatex and reinstall. Unless of course the fitting is damaged somehow.
