Valve cover paint coming off.

Hi Saul

Generally none of the operational fluids will be an issue.  The only fluid I am aware of that attacks paint is brake fluid, it will do exactly what you say is happening.  Check for leaks in a fitting or line if you have any brake fluid leaks. Consider that the plastic covers for the injector (it dresses up the stainless fire protector under it) is also green.  I have not seen these flake any paint as yet but it may be possible. 

Cheers

Thank you for your response.  I actually figured it out.  I found a fuel leak dripping on the one valve cover. The fuel was blowing around and evaporated leaving the dye behind.  The valve cover has some streaking on it and I am not sure I can clean it up.  I feel like an idiot not suspecting a fuel leak.  Now to redo the fitting.

Thanks for responding.

Best regards.
