I found that orange stuff along a seam and some sheetmetal on my engine
today. No question but what it is comeing frm a head. It's aint much,
but it's there.

What's the success rate with plugging this kind of  leak with some kind
of stop-leak additive to the coolant

What would the list suggest as a good head-leak-stopper-upper?
