Checking Valve Tightness
- Clean the combustion chamber and valve seats. Use a rotating wire brush for example. Wash the cylinder head.
- Refit the intake valves and fit new exhaust valves. Fill the intake and exhaust chambers with methanol. Do not spill.
- Check all valves for leaks. The fluid may dampen but not run out. If the valves are tight, fit the cylinder head, see FITTING OF CYLINDER HEAD (IN CAR)
- If the valves leak, clean and recut the valve seats and grind with paste. Check the valve clearances, see CHECKING VALVE CLEARANCES .
