Compatible Models
We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.
Compatible equipment / model
- Small-block Chevrolet V8 cylinder-head applications with matching valve-stem and guide measurements
- Aftermarket SBC heads using the same positive-seal dimensions
Product Overview
Blue smoke after startup, oil-fouled plugs, or oil use during deceleration can point to valve-seal leakage after ring condition, guides, PCV operation, and oil drainback are checked. A complete set services all 16 valves on a typical V8 head pair.
Small-block Chevy heads have been rebuilt and modified for decades. Engine name alone is not enough. Measure valve-stem diameter, machined guide diameter, installed guide height, spring retainer clearance, and seal outside diameter before ordering. Positive seals may require machined guides.
Key Features & Performance
- Complete 16-seal set for one V8 engine
- Viton sealing material for compatible high-temperature service
- Positive-style oil control where guide dimensions match
- Useful during head rebuilding or on-engine seal service
Common Uses
- Correcting startup smoke from hardened seals
- Installing fresh seals during cylinder-head rebuilding
- Replacing damaged seals after spring or camshaft work

- Product Type: Valve stem oil seal set

Frequently Asked Questions
Q: Will new seals fix all blue smoke? A: No. Worn guides, piston rings, PCV problems, or oil drainback issues can also burn oil.
Q: Do all small-block Chevy heads use the same seal? A: No. Stem and guide diameters vary, especially on rebuilt and aftermarket heads.
Q: Why check retainer clearance? A: A retainer that hits the seal at full lift can destroy it immediately.
Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
