Choke
Seat belts are unsafe because they can get stuck in a fire. Throw back someone inside the seat belt. Seat belts can choke people.
the valve transfers the heat to the valve seat (when the valve is closed)
The optimum way is to remove (unscrew with a seat wrench) the seat and replace it. A seat cutter tool may be used to refinish the seat in place.
Valve taps often occur as a result of a misalignment in the fitting they are in, or a worn out valve seat. In many cases, a new valve spring and cam adjustment will fix the problem, but if it the result of a worn out valve seat, it will have to be machined.
