GFB Respons TMS Valve (part T9001) - Manual (Page 4)

Maintenance
GFB blow-off valves are designed to be as maintenance-free as possible. In most cars the small
amount of crankcase and rocker-cover oil vapor that is directed into the intake system is enough to
keep the piston well lubricated. However, if you notice the sound of the valve changing over time
(e.g. slow response time, intermittent operation), or if you can see that the piston is not moving
smoothly, it may require a clean and re-lube.
Put a rag under the valve to catch any parts that may drop. Remove the four screws holding on the
cap, taking care as the spring will try to push the cap off as the last screw is removed. Remove the
spring and the brass piston, and wipe any grime from the inside of the valve and the piston with a
rag. Apply normal engine oil to the piston and the inside of the bore, and re-assemble.
