I'm assuming that these areas circled in red is where the plastic melts or warps causing an oil leak into the plugs?
I wonder if we can simply reposition the seal or O-rings....maybe apply some gasket sealant in these areas?
IMO, buying a new one will eventually melt and leak after being exposed to the heat. It's about $200 a cover for each side. If your out of warranty, that's $400 if your unfortunate to have leaks on both sides. That doesn't even include the gaskets.
Man!... what a stupid design by nissan
