Cool PCV

to you technicians out there, how in the world to replace the PCV valve on a 93 Lightning? I know it is behind the plenum...so how do you remove the plenum? I looks easy for the most part, except, how do you remve the plenum where it meets up the the throttle body spacer? It has 150,000 miles on it, do you recommend that I replace the PCV? There is nothing wrong with the way it is currently running, I am just performing preventative maintence. Also, were is the PCV Screen? Should I replace that ???

The upper plenum should just unbolt and come off. The screen itself should be underneath the valve. Pull it and just spray the crap out of it with brake cleaner or throttle body cleaner. If it comes clean, just reuse it.

It can be replaced without removal of the upper, but its not easy. You'll need a mirror to see just what your doing and be careful not to break any hoses or such. If it's got more than 30,000 mls on it, it should be replaced.
