So I bought my first car the other day 1.2 clio, and I did so many checks but looks like I missed one out, and yes a very basic one! I'm angry at myself for not checking it properly so please no negativity, help is all I'm asking for. 
I took my oil cap off and there is white gunk on the underside of it? Is my head gasket going? What else can I look for? And how much to fix it if it is gone?
Thanks in advance.
