Why We Use Glyptal Coating Inside Engine Blocks (It’s Not Just Paint)

Glyptal isn’t just a paint — it’s a high-temp sealant that protects critical surfaces inside your engine block.
In this video, we show how and where we apply it, and why it matters for performance and longevity.

If you’ve ever seen a red coating inside an engine block and wondered what it is — chances are, it’s Glyptal.

This high-temperature, specialty enamel isn’t just for looks. It’s a proven solution used in performance and racing engines to:
✔️ Seal microscopic casting pores
✔️ Improve oil return by smoothing interior surfaces
✔️ Prevent contamination from casting sand and debris
✔️ Protect internal surfaces from corrosion

In this video, we walk through where and why we apply Glyptal inside the engine block — typically in areas like the lifter valley and inside oil return passages.

Whether you’re building a street beast or a high-rpm track car, this kind of detail work can make all the difference over time.
