V12 Piston/Liner Replacements
MODEL XJ-S
DATE 5/91
ISSUE:
Correct installation of replacement pistons and liners on V12 engines.
ACTION:
Individual pistons and liners are sold as a matched pair. Pistons must ONLY be replaced with the matched liner.
A mix of "A" and "B" grade piston/liner sets is allowable in the same engine.
NOTE:
The XJ-S Repair Manual Section 12.25.26 incorrectly states that replacement cylinder liners must be of the same grade as the original liner.
