Brake cleaner can probably clean it up nicely. Check your PCV valve, that is the crankcase vent hose. The hose may also be a little old and hardened too, may have to replace it.

N.E.O.

Kool where exactly is the PVC valve on the Gen3 V6 engine ???

on the rear valve cover under the intake plenum

it's always a good idea to check and replace your pcv since it releases pressure as needed...often you can get more blow-by from the crankcase vent or leak from your rear main seal, etc because your pcv isn't working properly

At the front corner of the rear valve cover, I believe. Can't be 100% for sure, since I haven't seen one of them for a while. Anyway, it is somewhere on the back valve cover.

N.E.O.

Any pic guys ???
How much does it cost???

Derrick

Sorry no pict! It is probably around $20 including the grommet, which usually falls apart on an older engine. Don't know about down under though.

This link is for a later model 3.0, but should be fairly similar to yours: new PCV valve (PICS)

N.E.O.

What is the main reason to replace the part?? bad idle ???
Does it improve mileage (spelling) ???

Derrick

No so much to do with improve mileage, well, maybe just a little. When the PCV system is operating, it lower the crankcase pressure, so oil won't get push out through the seals and gaskets when the engine is turning high rpm. A stuck or plugged PCV valve could cause excess oil consumption, oil leaks, etc

Most of the time it is replaced for maintenance purposes.
