got some buick aluminum valve covers and drilled out a whole for the breather. put it in, but every time i drive it hard, i get oil seeping out of the breather. any suggestions? pete
Its pretty common, and its hard to get a good seal around the grommet to valve cover. The rocker do sling ALOT of oil under the covers. Plus if you have a bit of blow by past the rings, it exagerates the problem a bit. Mark
