Possible rust on valve spring
Hi,
I hope I'm in the good section.
I recently openned my gasket cover because it was leaky and had to change it. In the process I discovered a rather clean part and most of it didn't worry me, until I took a closer look at the valve springs.
It appears at least some of them have what looks like rust spots I did not confirm the nature of those as I didn't dare touch them.
I'd like to have your opinion on these, is it a common occurence? Should I monitor the progress of those spots?
And as a picture speaks a thousand words, here's one of the concerned valve spring:
