Need help with an oil leak

Just put a new rear main and valve cover gasket in. Was good for a week or so, then went for a long drive through the mountain passes. Got home and there is a tiny bit of oil on the bottom of the bell housing. Put a better valve cover gasket on and new PCV valves in. Still having the small leak. It drips maybe a drop or two after I drive it, but after all the work I did its driving me nuts not knowing where its coming from. It isn't wet enough anywhere to follow the oil to a source. Any tips or tricks to help locate the small leak? Thanks

Try an oil leak detection dye. You'll also need the light. Cost you about $23.00 on Amazon.

What motor do you have? If it's the 4.2, you'll never get it to quit leaking. A lot of older Jeep guys I've talked to said if you can get one to quit leaking you need to tell them because they've never figured it out.

I'll try the dye. Its much cheaper than I thought it would be. I have the 4.0 in it. It had no leaks until just over 110,000 miles. i had it dry for a week or so but now it just leaks a tiny bit. Thanks for the dye tip, I'll try to get some this weekend.
