there are two expensive services on those engines.
the first (ouch but not WOW) service is at 10 years cambelt change, sorry dont know when it required on newer engines but there will be an hours run equilavent
the 2nd (WOW-WE) is a full head off and piston ring replacment. I'm thinking thats @ 1200hrs.
must be an old wives tale then. despite being 10 years old now, were still under 1000 hrs, but unfortunatly like a lot of 6LP owners, not on the same bravo drive
Ive always wanted to ask an expert about the whole "wash the turbocharger" thing. the manual gives specific instructions to put a measured qty of water through it doesn;t it, it is as simple as that?
