Ok since I had to get the answer from the Triumph people I'll give yous guys another shot.
On a "B" under the exhaust manifold is a cover or 2 on the block. What is this to and is there something behind it that would leak oil, I mean a lot of oil??
Is this a common leak spot?

The two plates cover the lifters, so yes it is a potential leak if not installed correctly. The oil behind the cover is not pressurized so it won't spray out in great volumes, but it will be an obvious leak. It may seem contrary to logic, but you do NOT want to tighten them very much, maybe 7 or 8 lbs/ft at most. Reason being that you may bend the cover which will guarantee that it will never sit flat again, and you may squash the seal too much and create leaks there as well.
Also note that the front cover has a vent tube which is connected to the PCV valve (if your car is so fitted). The rear cover has no vent.

My brother has that tube running straight to his Down draft Weber.
Does that pipe suck or blow?
There's so much oil that it is hard to tell where it is coming from. At least on that side the ex. manifold is somewhat clean and real greasy oily below it.
How often do the crush washer on the oil cooler line to the block leak?

I don't know anything about downdraft Webers, so I'm not sure what that's all about. It will also depend on what year his car is and what emissions gear it originally had.
The early cars had a hose running to a PCV valve which was connected to the intake manifold. Later ones connected the PCV valve directly to the carbs. I'd recommend putting the valve back in if it's missing. Alternatively, some people put a small air filter on top of the side cover vent tube. The tube's purpose is to vent crankcase gasses. The PCV valve sends the gasses to the intake where they are recycled, when appropriate.
