I tried to remove the oil cap today on my XJ 4.0L, and the cap wouldn't unscrew - it felt really tight, like the last time I had an oil change that really cranked it down.
I tried to exert slow pressure, hoping it wouldn't break - but it did. And the part left in the valve cover appears not to have anything sticking above the valve cover, so there's nothing to grab on to.
1) Am I right that the ring / lip that is sticking up, is a part of the valve cover, not a part of the cap? Any suggestions?
2) What is the best deal on a non-ratcheting replacement cap?

Is there a good non-ratcheting replacement cap anywhere?

Mine broke the same way. Like CCKen said I also used channel locks to take it off. I still haven't changed it out. I have a flat piece of metal that fits in the grove and I use it like a key to take it off when needed. I'm just t cheep to buy a new cap.

remove the spring. But some devcon 5 minute plastic welder. Mix some up and put it in the hole then put the cap on and wait 10 minutes. When the plastic welder starts to cure it will get hot. then remove the cap. Check with your local NAPA for Stant 10111 or Balkamp 703-1713 oil filler cap. About $8.50 w/tax

Go to O'Reilly's and get a Murray cap. They don't ratchet and are similar to the earlier OEM cap.
Get the remnants off with Channel Lock pliers.
Next time you're in Walmart, get some 2.5-3.0X readers for your failing eyesight.
