Jaguar vehicles with the V8 engine, can experience partial blockage of the restricter in
the engine part-load breather during normal service. This blockage would restrict the
correct operation of the engine breather system.
Until further notice, Jaguar Cars is introducing a routine cleaning procedure for this
restricter. Initially this procedure should be performed at the first service opportunity on
any XK8 or V8 XJ Series vehicle, that has already covered more than 10,000 miles
(16,000 Km). This cleaning procedure will then be performed at scheduled
maintenance intervals of 10,000 miles (16,000 Km). The frequency of this cleaning
procedure is listed below.

procedure should continue to be included in all scheduled maintenance visits at
multiples of 16,000 Km (10,000 miles).
