My PCV is screwed into a fitting on the intake manifold. A 3/4 inch wrench should work. Saw one on ebay,maybe take yours off and clean it but, I read somewhere that there may be an oil baffle on the block by the pcv hole ,could he have broken it off?Good luck, Try the overheadcam forum to they might help you over there.
