You're right about the tensioners being mechanically preloaded. Good point as well, regarding the timing chain tensioner as a preventive maintenance item.
However, the oil pump chain doesn't appear to have a separate tensioner part, and if it did it would be pretty invasive work. Is it integral to part number 6 in this drawing? Maybe...
