i just change my pcv valve and when i pull out the old one it has oil on the tip side that goes in the engine its that normal or should worrie?

also i put the new one in and it seems not to go all the way in but i pull it and its snug should it be all the way in?

 

Wiggle it in. That rubber moulding has been warmed up and cooled down a gazillion times it ought to be a bit britlle and hard.

 

what about the oil on the old one tip

 

Umm not to sure about that, lets let the other guys handle that one.

 

yes. oil is fine. and no you dont need a catch can.
