"NOT INSTALLED ANY OIL ON THIS ONE!" Like someone bought a valve cover from the local Nissan dealer 35 years ago with the intent of making it a show piece or collectors item? I think.. someone bought a new engine (with the message: no oil in this one) and installed the cover of the replaced engine and now the new engine's cover was obsolete.. and has that sticker still on. Aitoku is a firm that deals in engines probably? btw. my 1979 280zx has also a yellow flaky valvecover, it's still original.. nothing done to it yet.. (if you ask me these were coated with some blank paint) Edited October 22, 2020 by dutchzcarguy 1 Link to comment Share on other sites More sharing options...
CanTechZ Posted October 22, 2020 Share #50 Posted October 22, 2020 I wonder if from factory they used a clear chromate conversion coating like clear alodine to give a small level of protection. Link to comment Share on other sites More sharing options...
Mark Maras Posted October 22, 2020 Share #51 Posted October 22, 2020 The early 240s valve covers I've cleaned (usually with lacquer thinner) had no coating. I believe that's true of the later ones too. Link to comment Share on other sites More sharing options...
