to make Piets post a little clearer by "bores" he means the stud holes, on the non coler types the oil is fed from the oil pump direct to the cylinder base gallerry, which is flooded, oil rises up the six outer stud holes and into the cam bearings where it literally sprays eveywhere draining by gravity through various routes includeing a drilling in every tappets bore, oil is also fed direct from the cyinder base gallerry into two seperate drilling which directly feed the centre mains, those two drilling are also staright and need a clean with cotton buds from time to time.the outer main bearings and the pistons are splash fed, nice and reliable and plenty of it sloshing around everywhere. Just grind off the addedd crap and all will be revealed, I dont think this will be hard to bring back to as was, the holes that you will need to fill will be quite small. The two extra holes in the primary case are no bad thing and to get the same effect was stock on later models, although not looking the same as yours, BUT>>>>>>>is that a crack I see leading to the gearbox mainshaft bearing????? and I seriously dont like the look of the red Hermetite, oozing out, on rebuilding use Loctite flange sealant (cant remember the number) piss thin, works very well, only hardens when air removed, so any excess does not set and is washed away, there shouldnt be any to start with though. Chassis number and rear shock mounts make me think it just might be a very, very, late drum braker??????? special order??? 304, surely not, cant be arsed to look in records.
