 If that's a static leak, a pressure test would likely confirm your suspici=
ons.I checked a cut-up head that I have, there's a good bit of meat around =
the plug hole but if there's heavy corrosion in the water jacket, that coul=
d be the culprit.Glen

I=E2=80=99m wondering if anyone has seen anything like this in the attached=
 photo. I found some coolant pooled around the number 4 spark plug on my TR=
4 head. I took this photo about 10 minutes after cleaning it up. Stone cold=
 engine. It appears I=E2=80=99ve got coolant seeping through the head at th=
at point. The crack is not in the threads as I had feared. Logic tells me t=
his may not become a critical crack, but I don=E2=80=99t know the topology =
of those passages well enough to be certain. Might I soon be in search of a=
 new head, or is this repairable? Could it be a crack or is it corrosion? T=
he head part number is 511695. Would love to know what you all think.
