Huh??? AFAIK, the only way oil can get into the intake runners is if there's a blown intake gasket or a cracked intake manifold. That could also cause a lack of vacuum and engine dying. I think I'd be seeking another opinion from a different mechanic.....don't give up on the old Z just yet. Beautiful car!
