kevin_m 0 Posted January 14, 2009 there is a horrible brown gunk on the under side of my oil filler cap, does this mean that the head gasket is about to go? Quote Share this post Link to post Share on other sites
dinkus 10 Posted January 14, 2009 Does it look suspiciously like oil? :lol: In short - I doubt it, it's probably just congealed oil. If it's white and mayonnaise like, then it's water and cause for concern (but only if it doesn't go after taking the car out for a nice hot run).
