Thread sealant
When setscrews or studs are fitted into holes which
are tapped through the cylinder block, a suitable
sealant must be used to prevent leakage.
Micro encapsulated anaerobic sealant (M.E.A.S)
fasteners have been introduced instead of jointing
compounds or other sealants when the fasteners are
fitted in through holes into oil or coolant passages.
The identification of these fasteners, as supplied, is
by a red, blue, or other colour sealant around the
fastener threads.
With M.E.A.S. sealed studs, the sealed end must be
fitted into the cylinder head / cylinder block etc.
Ensure that the threaded holes have a 1,59 mm
(0.0625 in) 45° chamfer, to ensure that when the new
fasteners are fitted the M.E.A.S. sealant is not
removed. If the fasteners have to be removed and
fitted again, the threads must be cleaned and a
suitable sealant used.
