good luck man! its not to hard just make sure everything is torqued down right! its like 11 or 20 INCH pounds i believe and then retorque it at 50 and 200 mile marker
You can pull the first breather and put a filter on it, I WOULD NOT pull the second one.
The first one is for air to come in, the one in the back pulls the air out, along with all the nasty hydrocarbon vapors to be burned.
If the back one is pulling oil into the intake, take the hose off and clean it out real good, use a screwdriver in the grommet hole to get the carbon out.

goldenlandscaping,
I changed the valve cover on my 94 XJ 4.0L this past weekend. Took about 2 hours start to finish - taking my time. I pulled off the hose from the thermo housing (as Tural mentioned), but I also removed the accelerator cable bracket (just to the right of the breather as seen in your picture) to give myself plenty of room. The bracket has 3 bolts and the 3 cables just unclip from the bracket mechanism.
The old gasket was leaking pretty badly, some of the valve cover bolts were removable by hand.
The old gasket looked like shrivelled paper. I replaced it with a FEL-PRO rubber gasket (much much better quality). Get yourself an inch-lb torque wrench and only tighten the valve cover bolts to 55 inch-lbs, starting from the center and working your way out.
It's not that difficult, you can do it.

If the PCV or CCV valve (which ever one you have) is working it should not affect vacuum. However do not plug the hose it has to allow air to circulate in the engine or you will build up too much pressure and cause all kinds of oil leaks!

Order a new front vacuum assembly from rockauto. Its only $15 and it replaces other vacuum lines as well. If something is leaking oil its time to replace. Love your baby and waste all your money on her.
