[Healeys] no oil pressure

The pump does work.  I typically fill the oil filter before installing 
it.  I took the filter off and install a new one dry.  Spun the engine 
on the starter for 20 seconds or so and removed the filter.  It had oil 
in it.  There was still pressure in the system and it "popped" as I 
loosened the filter.

Still no oil pressure at the gauge or oil at the rocker arms.

With the filter removed, I can stick a depth gauge about an inch into 
the engine block (both inlet and outlet).  As installed, the filter 
inlet hole is at about 10 o'clock right now.  I don't think that the 
adapter can be installed so just one hole blocked, but I'll remove it to 
confirm it's on correctly.  It's easy enough to do.

The oil path divides after leaving the filter, one to the rocker shaft 
and one to the main bearings.  The gauge is on the latter.  Not seeing 
oil on either path seems to point to the filter/adapter.

Back to the garage.
