Pre fill the Filter ??....I am not so sure why given all the potential mess involved......


I have found that Camshaft bearings and rod bearings maintain oil for a very long time with engine not running (like years).
The Lifters also maintain oil on their surfaces for a very long time as do the Cams.

Likewise the Chain Guides maintain oil for a very long time. The Chain tensioners will bleed back oil but it has been said that Start Up Loose Chain guide slap is just a noise and no harm and no foul mechanically. Having said all that......pre-filling the filter definitely does not hurt the engine in any way
