Well this got interesting. Pulled the valve cover this morning and found this special treat... Put it back in place, put everything back together and it runs like it used to but is still ticking.

Some updates since I had some time to work with it today. Put new plugs in just on a whim. No difference. Disconnected exhaust to check for clogged cat. Much louder, no better. Did a compression test. All came back around 120 per cylinder. Battery had gone flat and it was just coming back...

Thanks Cruiser! I'll look those over and make sure all is good with those. Your site was a massive help when I originally got this Jeep back on the road last year!

Flexplate bolts are all good. Just confirmed.

Ok - got it started and the alternator looks good. Battery was up over 12v when I started it and read over 14 when running. I was able to drive it briefly and it drives ok (not great) other than the noise. I did notice it gets worse as RPMs rise, but dies off above 4k. Links below include a...

Thanks everyone! The battery is charging now, so I'll report back after it's charged up and add a video of how it's running then if it isn't resolved. I checked the vacuum to the MAP and it looks like it's good. Will investigate further once it can be started. I think the fuel pump is fine...

Ran into some trouble with my 89 XJ and hoping to get some tips to diagnose it. Finally had the car on the road and now its back in the driveway. Everything was running ok (didn't seem perfect) and I took it on the freeway to run an errand. On the way (downhill) I started noticing hesitation...

Thanks everyone. The leak is definitely in this area. Valve cover was leaking pretty bad , but gasket has been replaced and is verified not leaking anymore. This resolved most of it actually. Have also confirmed no leaks from the oil filter adapter. It's hard to see in the picture, but...

Will give that a shot. What would oil on the flex plate indicate?

Working on curing all our XJ's oil leaks and getting ready to replace the rear main seal. When I got under the car today to double check the seal was actually leaking before jumping in, I realized there seems to be a gap between the back of the oil pan and the transmission? Trying to figure...
