Artie:
Ade, dont forget this is the scavenge side of the pump, oil cannot leak unless the engine is turned off. dont fret too much about oil tightness, it isnt an issue as what oil there will be, when shut down, will only be 'pooled' and will only seep, and only then if you have a major issue. Leak gone as soon as you start the engine. Also

With the intererence fit and suitable loctite this will never move (not even when you want to!) chech out www.loctite.com. The temps you mention are not extreme for the average loctite product, dont forget they are designed to work in an engine environment, particularly the racing environment.

Personally I would go with the flat plate bolted on the end because after an engine blow (it happens) you are going to have to be able to clean out the galleries, plugged as you describe would make this a difficult job.

Refer to the comments above, this is not a high load hydraulic joint, it is a slight vacuum joint. A plate with 3 o rings would be much much more than is needed. # staggered height Earls 90 degree fittings would give you the clearance you need.

Cheers Artie

Darren:
You can still separate the plugs for more room, a plate wouldn't affect that.

I just feel a plate clamped down by say four bolts with a ptfe or other gasket would be the safest and easiest all round. Just a rectangular plate and gasket. As Artie says, you can then pop the plate off to clean it all out at a later date.

yes, to look it another way - its just an extension of the sump. Engines often make do with one of pressed tin with just a cork or card gasket ....

andyf:
Just a thought - if using plugs, might it be a good idea to drill and tap blind holes in them at this stage, to make extraction easier if/when you ever need to get them out?

AdeV:
Interesting thoughts chaps.... can someone do a C-o-C of this plate idea? I'm assuming that it works as per the below (please excuse the ASCII-CAD):

]-T-------
]-+-T-----
]-+-+-T---
| | |
| | |
| | |

Key:
| = cross-drilled pipe
T = cross-drilled pipe meets end-drilled pipe
- = end-drilled pipe
+ = cross-drilled pipe crosses end-drilled pipe
] = plate bolted on end of sump

i.e. at the point of intersection, all three pipes are inter-connected?
