Pencil whip overhaul on Turbomeca Marbore

I saw with some aircraft owners that some Turbomeca Marbore II and VI had a Major overhaul done on the engine by some unscrupulous person entring in the engine log "inner and outer basket inspected and returned to service IAW maintenance manual limits for serviceable "
Turbomeca never , I said never authorised a Marbore II or VI to have a major overhaul without replacing the combustion chambers ( inner and outer ).
So be careful, instead of having an engine with fake 300hrs TTSMOH total time since major overhaul, you have an engine with real 2100 TTSMOH hours since real major overhaul so 300 hours past the TBO due time.
Be aware of theses pencil whipping overhauls.
