Neil,
First, the rear seal can be changed without pullingthe engine. However,
the transmission and assorted goodies have to be removed first.
The front seal can also be changed without pulling the engine but talk
about a lot of work. May as well pull it and do both, but I don't think
that's where your problem lies.
If it's the original front seal in the timing chain cover, it used
leather as a sealing medium and odds are that it dried out while sitting
so long.
You really have to be tender with the oil pan gasket. Overtightening
can crush the gasket and produce more leaks than it stops.
Changing oil viscosity is a good idea in Summer, but, with the thicker
oil, comes slightly higher oil pressure, which pushes oil through all the
passages as well as any source of leaks.
Probably a good idea to wash down the engine real well and then search
for the leak.
My first guess is going to be timing chain seal.
Sorry, no real words ir encouragement.
Best Regards,
Tony
