NOTE: Make sure engine is assembled using all specifi ed torque values, tightening sequences and clearances.
Failure to observe specifi cations 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
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 closure plate, crankcase, cylinder heads, to be certain 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.
