Hi y'all, this year I got myself a 1.6 Jetta in rough shape. It starts up every time now, but after sitting idling for about 30 minutes it blew a bunch of coolant out of the overflow reservoir.
I started it the next day bone cold, with the overflow cap off, to look for bubbles from a blown head gasket, I see no bubbles but coolant is flowing into it from the small pin hole near the bottom. Pretty certain that's wrong. Do you guys have any advice on where to look first?
