5 Series E34 518i (M40) SAL
Slight material loss on the insulator due
to spark erosion during operation. This
loss is not in the form of cracks or
fractures, but rather an intended
"channeling" in the tip of the insulator,
which does not affect operation.
Soot fouling
Caused by faults in the area of the
ignition system. Causes
by-passes with subsequent misfiring. It
is advisable to change the spark plugs.
Oil fouling
Caused by excessively high oil level or
by wear in the piston rings and/or in the
valve guides. A change of spark plugs
is necessary as misfiring will occur.
This is not a defect in the spark plug
which qualifies for reclamation.
