NOTE: Make sure engine is assembled using all
specified torque values, tightening sequences,
and clearances. Failure to observe specifications
could cause severe engine wear or damage.
Always use new gaskets. Apply a small amount
of oil to threads of critical fasteners before
assembly, unless a Sealant or Loctite
specified or preapplied.
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 oil pan, crankcase, and cylinder heads 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.
