On the early -800 series Billancourt engines like mine (prior to about 1969/70 or thereabouts) there was no oil filter or provision for one. The equivalent Billancourt -670 engines for Dauphines apparantly had a couple of tapped holes capped off with setscrews that could be removed and an aftermarket oil filter mount added, this came in around 1960 and those kits are still available. From what I can see on my engine the lug positions are there but the oil pressure tapping is used for one and I can't really see if the other has been drilled, tapped and filled. There is another setscrew around there below the fuel pump not in the same place, but I'm not sure of it's purpose.
Does anyone know if there was a similar available set-up for the R4? I'm keen on fitting something next time I pull the engine out. Or does anyone have good pictures of the LHS of an early engine? If there are existing tappings I can use that would be ideal (fat chance I know).
Cheers
