i think my opti is going bad. should i replace it with an vented opti or should i just get a regualr one like i have?, would a vented opi make any diff? and is it more expensive? what all would i have to do? just drill a hold in my intake elblow, for the little hose? help please. plus later down the road i might put a cam in it. do vented optis, run better or last longer or something?

 

A vented Opti actually costs less. Problem is, you can't put a vented Opti on a 93 unless you change a bunch of stuff, like the timing cover, cam sprocket, cam, etc.
