I would sure like to know if anyone has fixed these cracks. Mine has a slow drip, its a nuisance, and it cools just fine. Anyone know of an inexpensive fix? Six months or so ago, I saw a product advertised that had an insert to support the neck and I believe it was epoxied into place after draining the radiator but I have not been able to find the product or the link again. Can anyone help? Thanks, Steve
