Coolant leak -hydro locked engine

I'd say it depends on your budget and your comfort zone.

But it seems fairly simple really. "You" have to decide on your type. If your the nervous or rich type - throw money at it now (daily driver/wife's grocery getter). Never leave the wife on the side of the road if she's any good. If your the good olde boy type (budget race, great depression era/early boomer/like to marvel at your own genius). Repair and worry about it if it fails next time.

Me, I'm a mid boomer and watched granddad/father pull some great repairs. Think hay season and the bailer's cast iron needle breaks. Brazed back together years ago and still going strong. But I also watched them have to dig out broken wooden fence posts and replace (it sucks). They didn't have the budget then. I have the budget for metal now, and that's what I use.
