See attached pix. One picture is from below the other is from side. Believe=
 the timing cover seal is leaking. Been 40,000 miles and 10 years since reb=
uild. Head gasket does weep - about a quart per 6,000 miles - copper head g=
asket .093 thick required because of extensive shaving. It has now gone to =
a quart in 1,000 miles which is what it was before rebuilding diagnosed lea=
k as timing Cover seal. Leaves a drip on ground when stopped only about 2-i=
nch in diameter. Seems really small for usage, last time left much bigger d=
rip.
First, does it look like timing cover seal to you?
Second, I have limited tools, no lift and am afraid I cannot get crank bolt=
 loose or pull the crank pulley off. Can probably deal with the rest. Sugge=
stions on nut and pully removal?

Tech session at my house anyone? LOL

Hello Peter,
The first thing to do is perfectly clean the engine, especially around the cover.  The leak will be much easier to pinpoint.  
I have seen a few covers with holes worn into them from the chain tensioner.  Over time, the hole gets bigger and leaks more oil.  
Leaks could be from gasket seal failure, or crank seal to.  If you clean everything first and it's leaking that much, you should see the leak after a short drive.  A dusting of a powder could help.  
Have you checked the tightness of the cover fasteners?   Loose bolts will allow the gasket to fail.  The cover will need to be resealed.  
Check the oil pan bolts to, being careful not to over tighten. 
 
Dave H.
