Make sure all traces of any cleaner are removed before
engine is assembled and placed into operation. Even
small amounts of these cleaners can quickly break down
lubricating properties of engine oil.
Check closure plate, crankcase, cylinder heads, and
valve covers to be certain that all old sealing material
has been removed. Use gasket remover, lacquer thinner,
or paint remover to remove any remaining traces. Clean
surfaces with isopropyl alcohol, acetone, lacquer thinner,
or electrical contact cleaner.
