DC-8s, not Lancairs.
ENGINE
Clean the engine with a neutral solvent. While
the engine is warm but not hot, spray with solvent and
allow to set a few minutes. Follow with a spray wash
and allow to dry. Avoid excessively high pressures
which can force entry of water and/or solvents under
seals resulting in contamination of the sealed system or
entry through the firewall into the cabin. Use caution
and protect any electrical relays or switches you may
have installed in the engine compartment as well. Use
only solvents which do not attack rubber or plastics.
