Renault twingo head gasket

[Rstringer91]

Hi guys my twingo gt has a orange look to the oil cap? I heard this could mean head gas.
but I also know could just be a tiny water leak or because it does short Jeormeys a lot so doesn't heat up a lot? I don't k ow a lot about cars so please help should I just get if looked at properly? Does feel a little not as responsive too
Thanks guys

Clean the cap, take it for a good hour or so blast up the motorway. See if its returned.
