True, I'm a big stickler for following the factory manual and procedures. But often with older cars sometimes the collective wisdom of long term owners develops a slightly different procedure for doing things that may save a lot of money or time, or just make better sense.
For example, the LR manuals don't mention upgrading the oil cooler lines on the NAS V8's , but everyone does it.
Or, the early 2000s Porsches had a notoriously weak IMS bearing, which led to aftermarket fixes not officially endorsed by Porsche. (Google "Porsche IMS bearing failure")
Me personally I try to follow factory specs and procedures but just presenting the other side of the coin.
