Review on 🔧 Enhance Engine Cooling with Mr. Gasket 2557 O-Ring Style Water Neck for Chevy Engines by Mark Powell

Leaks due to incorrect NPT connection. It got less leaking because it was actually leaning against it with the crowbar 1/2. I was frustrated because it was leaking and really went for it, the case cracked. Contacted Mr. Gasket/Holly for advice. CS at Holley stated that this part sold by Amazon is fake! Now, without seeing that detail, I'm not sure how Mr. Gasket/Holly can make that claim, but they didn't seem willing to work with me. So remember, you will not get any support from Holly/Mister. seal when you purchase this item.
