Forrest 35 Report post Posted December 15, 2009 Its probably the protective wax it came with from the factory maybe. Try brake cleaner. Quote Share this post Link to post Share on other sites

antil33t 90 Report post Posted December 15, 2009 ahh well, if it's to protect the metal I better leave it then eh? I'll just have to paint the intake manifold and cam cover eventually Quote Share this post Link to post Share on other sites

I'll just have to paint the intake manifold and cam cover eventually If you take it off it will be fine. Im not 100% sure but I thought it was for imported vehicles that came over on ships and was to prevent corrosion from the salt air / water. If you take it off, your valve cover / manifold isnt going to corrode. Quote Share this post Link to post Share on other sites

hotwire 352 Report post Posted December 15, 2009 This can also be clear laquer that car dealers have sprayed on to give "the look". A look that certainly doesn't "look" later on Quote Share this post Link to post Share on other sites
