[urq] Leaky oil cap

[Andrew B]

Update:

The lines on the top of the valve cover are clear.  The one-way valve
appeared to be not working, so I replaced it with one from my
replacement engine.  It now smokes when I hit full boost.

There is a small red cap in the junction for the manifold vent.  There
is no cap in the old manifold.  There is no cap on intake vent line.

I discovered yesterday that my oil pressure sender wire was loose.  I
pushed it on further, but no help.  Could it be toast?  I have a
replacement one, but am having a hard time replacing it.  I'll look
into getting the proper tools if it might help.

Any other suggestions?  I fitted a second seal on the filler cap and
it's no longer leaking, but there's still oil collecting from
somewhere on top of the intake manifold.  I can't figure this out. 
Now I'm smoking in addition to leaking, but the leak seems to be at a
slightly reduced rate.

going nuts,
