Can anyone tell me the actual name of these two parts on the top of the valve cover?

[QUOTE="Gilaguy23, post: 436608, member: 19498"] The front one is a PCV valve or "Positive crankcase ventilation" valve. They are typically $5 or so at any auto parts store. You should be able to hear the check ball rattle freely if you shake it a bit. Although my 91/4 cyl is different a bit there is also a rear line like yours. On mine it goes to the air box so it can suck in filtered air into the engine. To prevent a oily mass inside the valve cover there are baffle plates at either hose location. Im guess in on yours it may be a empty can or sorts or what is called a "catch can" the oily mist can accumulate and drain back into the engine. Could be wrong on this one but its my guess. At any rate DO not destroy any parts that you might think are worn out and easily replaced as some are not by a long shot, like that "catch can" as I call it. Your TBI injection was only used a few years and may prove to be a bit difficult for replacement parts when needed. [/QUOTE]
