- Machine work
Why It Matters
Air-cooled VW exhaust valves run very hot, especially in a Beetle with tired cooling tin or a lean carb. Burnt or cracked valves cause low compression, a miss and rough running. A dropped valve head will wreck the piston and cylinder head.
When a head is rebuilt, the valves are replaced along with the guides. Getting the right head diameter and stem size for your head is the key step. These JP Group valves use the stock 3-groove keepers, so stock springs and retainers fit.
Installation Notes
- Valve work needs a machine shop or the right tools to check guides and cut seats.
- Measure your old valve head and stem before you order.
- Lap or cut the seats so the new valve seals fully.
- Use new keepers if the old ones are worn.
- Set valve lash to the factory figure after assembly and recheck after the first run-in.
- We do not publish torque values here; use the factory workshop manual (Bentley) for your vehicle.
