the homie just got an ef and it has a single cam zc in it. it has a metal cover over the mount where a vtec silanoid could go. this cover is not factory and it leaks oil when running. it runs and pulls fine threw the rev all the way to 6500 rpm like normal(aside from leaking oil). could this possibly be the later version zc that came with vtec and the distributer just took off the silianoid, or is there something else these motors came with that should go there?

 

here are some pictures of it. like i said right whare vtec silanoid could go.
