The whole top of the engine appears a dull gold, with what appears to be the "finish" worn off to a more shiny silver--when you remove the air intake which partially covers the engine cover, that part is the silvery color--I don't know if the silver is changing to gold due to heat or vice versa. Will check in on the dipstick seal--does it unscrew??

Thanks
