[QUOTE="swshawaii, post: 1031135, member: 67547"] Had the same issue with the driver side valve cover oil leak caused by a loose PCV valve, but didn't have lean codes. I believe my valve cover "'nubs" were broken off from the original owner over tightening. I read the only fix was replacing the valve cover, but instead bypassed the coolant hose using oil resistant RTV to seal the PCV valve. Years later no oil leaks. I'd give it a try, lot's of vacuum going through the PCV valve. Can post working pics if you'd like. [/QUOTE]
