Hey guys, a friend of mine has a 2006 Honda CR-V and the oil control valve on the side of the engine was leaking. He replaced the o-ring but then snapped the bolt off flush with the block/head. That's the only bolt that holds that thing on. Any ideas on how we could repair it? It's in a pretty tight spot, but the only thing I can think of is to find a drill small enough and drill/extract the old bolt
