I have an oil leak! There seems to be a crack just forward of the bell housing in the centre of the Vee.
When i throttle it oozes out. Only a small drop at a time and not at any great pressure. I,m assuming that the crack is in the cover plate and the actual leak is elsewhere but i cant be sure of this without a decent drawing of the engine.
Does anyone know of any good drawings or photos on the net?

Okay just removed breather filter and hose to plenum (by torchlite!!) filter was minging and the hose also full of congealed crud and lots of horrible fluids!
Not totally blocked as i could blow through them. After cleaning it was far easier to blow through.
Questions are:-
1. What does this system actually do?
2. How come considering, the fluids in the hose, its
not all ended up in the firing chambers via the
the plenum?
3. If this is the cause of my oil leak am i being to
optimistic in thinking that it will stop?
4. Is there an air void under the "valley cover" or
is there oil. If oil then can i just repair what
appears to be a crack?
Im asking these questions cause i still cant find a good drawing to see whats what.

Hope you can help cause the batterys gone in me torch
and im loosing sleep over it

Ps. Almost forgot to say, my tickover was at 1000rpm (high because when my cooling fans cut in there is a drop to about 800) tickover after cleaning filter etc. has dropped to 700rpm! is this indicative of blocked breather system?

Had nightmares about that photo on RPI site
paranoid about it as i know how many times ive overheated over the years.
Still not sure if oil is supposed to be there or is that cooked oil from a leak?
After last nights impromptu party ive thrown a sicky today. Pity its raining though, really must get a garage.
Any more answers or piccys out there guys?

Well ive finally figured out what this "valley gasket" is all about! i didnt realise that the whole tinny thing was the gasket! So the answer is yes there should be oil under it, i guess to lube the valve rod thingies!

So ive sealed the crack with araldite (theme tune from the good the bad and the ugly springs to mind but then ive seen worse cowboy jobs than this)
hopefully no more leaks anywhere else untill i can fit new one.

Cheers all.
