Don't know about Spain, but in UK there's no point trying to mollycoddle a Vendeneyef to extend its life (other than avoiding all possibilty of hydraulic lock). The engine is subject to a ludicrously short life before it has to be scrapped.
The one we had that was 'out of hours' and therefore scrap we stripped down out of interest. There was NO evidence of ANY wear at all. The machining marks were still pin-sharp on the cylinder bores.
