Additions:
1992 Mercury Cougar PCV valve screen. (Rock Auto part #6P1257) Many people (including parts counter men) don't know about this screen. It serves as an oil seperator between the engine and the PCV valve. With time they fill with crud and do not work. The resulting pressure in the crankcase can build up and cause leaks. Your PCV valve will eventually become blocked.

Part Comments
What came in the box? Were additional nuts, bolts, sealant, etc. needed for the repair?
Good part. Nothing else needed.
Repair / Installation tips:
Special tools needed? Have to remove other parts to reach this one? Any left-hand threads, sharp edges, messy fluids or other pitfalls to avoid?
This screen is hard to see. It is located under the grommet, which is under the PCV valve at the back of the HO 5.0 engine. You can see it with a mirror and a flashlight. I drove a 3 inch deck screw into the old screen and pulled it out with pliers. The new part just falls in. Install the new grommet and PCV valve, and you are done!
