Review on 🔧 Chevy O-Ring Style Water Neck by Mr. Gasket - Model 2661 by Cory Mosley

UPDATED. Perfect fit for my '78 Corvette. It can be difficult to install the o-ring correctly as it gets folded during shipping. Bought this for a new Edelbrock header. UPDATE: After two years, coolant started leaking. I noticed that the o-ring is a bit flattened. dry and seal with HT RTV. is still leaking. Dried and cleaned parts, paste the gasket with sealing adhesive, still seeping through. I take everything apart and check the surfaces with a ruler. That's ridiculous.
