Pipe caps??

[Bobbit]

I\'ve been looking at Rob Robinette\'s website (quality info there) and i\'m think of removing the PCV valve as the 95 rex dont have this compared to the 92-94 models. Has anyone done this and is it worth while doing? Also i will need some rubber caps/bungs/plugs to block off the ends of the manifold and oil filler neck, does anyone know what there cap thingies are called and where to get them?
Thanks for any help:Thumbs-up
