Oil leak near filter
I had to replace the radiator on my 1995 Cherokee Sport 4.0L today.
That went fine but while I was test running it I saw that I have a
pretty good oil leaking coming from near the oil filter. The oil filter
screws onto a 'thing' that in turn bolts to the engine somehow. The
leak is coming from where this oil filter thing attaches to the engine
block.
What is the name of this filter thing? Is this the 'oil filter stand'?
If so, where can I get the proper gasket for it?
I also ordered a replacement oil pressure sending unit a while back.
What arrived however was a sending unit for an idiot light. I am trying
to find the sending unit that runs the analog pressure guage.

Oil filter adapter. It uses a set of o rings and the best location
to get them is the dealer. Getting it off the block requires a
torx bit and wrench. You can see the bolt if you look into the
cavity left by removing the oil filter.

Should be NAPA MPE OP6695SB or ECH OP6695
Although it is called an oil pressure gauge switch.
If you have an auto tranny and cooler lines in the radiator, make
sure you keep an eye on the lower connection. It tends to leak
if you don't tighten it down enough. (nearly pumped all my tranny
fluid out one day before I found out)

This is called a filter boss. (Some also term it the adapter.) It is
O-ringed to the block and held together with torx bolts. Over time, OEM
seals harden and leak. This is a well known problem. Newer blocks
incorporate the boss casting which eliminates the need for O-rings
altogether.
If you source a new O-ring from the dealer, you'll get the same nitrile
rubber part, which will buy you another year or two before it hardens
and leaks again. Nitrile rubber takes a set too easily and doesn't do
well with temps above 200 degrees for long.
If you want to replace this part only once, go with a very high-temp
(>400 deg.) mil-spec ring. I suggest 70 Durometer Viton rubber. Stay
far away from neoprene and urethane O-rings - they can't take the heat.
There are a few good online sources;
I like http://www.marcorubber.com - they have just about anything you
could ever want in O-ring selection.
While you're there, check out their material chart:

You might check around town to see if someone local can order Viton
O-rings for you instead.
