[V8] Speed Sensor Solved problem

[dsaad at icehouse.net]

Look around here to see all the parts involved:

Your leak can be any/all of:
- the distributor shaft - which would put oil inside the cap
- the distributor base o-ring
- the distributor base flange to head o-ring
- the rear cam bearing cap (has sealant under it)
- the valve cover gasket
- spilled oil from an oil change (drips down in this area)
- oil blowing out the oil fill hole and leaking down under the spark plug cover
- same leak as spilled oil above

and there may be other ways I missed. Fortunately all of these are pretty easy
to fix. I would probably start by first doing a good engine cleanup so you can
see exactly where the leak is. Then remove the valve cover and inspect the
gasket. It is probably hardened so just replace it. Remove distributor and
inspect. Oil in the cap means the distributor is toast. Replace the o-ring, and
make sure the base flange is properly torqued. It would be very easy at this
point to simply replace the o-ring behind the flange if you wanted to.
On one side the flange has two o-rings, and the other has one. If I remember,
the right rear has only one and the cam bearing cap is fully inside the valve
cover so that may not be a possible leak source.
All of the nuts and bolts involved here are small. I always use a torque wrench
set to I think 7 pounds so I know they are tight enough but not over torqued -
which can cause gasket failure or worse strip expensive parts.
All the torques are in the manual.
