Repairing expansion tanks?
I found a pin hole in my expansion tank today. Anyone know of a sealer which will work on the inside? Possibly some kind of coating I can pour in and move around with the tank removed. Thanks, Carl

Do you mean the plastic recovery tank or do you have the pressure cap on the metal expansion tank tank like some of our cars?

If you clean it really good you can fix it with a high strength industrial epoxy like scotch weld. It may be a temporary fix however so you may consider getting a new tank from one of the corvette supply houses. They will even date code them for you car if that's a concern.

You can scuff sand the area on the outside of the tank and apply a smooth patch of JB Weld around the hole. When this dries, scuff sand and smooth taper the edges of the JB weld and then apply a one to two inch dia. patch using one or two layers of fine weave fiberglass cloth wetted with structural epoxy. I repaired a hot water tank for a camper this way, still holding :D
