Hello Mel!

You have to pull the engine to replace the main seal.

The main seal gets hard over time and begins to leak.

A hard main seal can damage the flywheel.

A new main seal will not last too long with a damaged flywheel.

This is a good time to replace the tranny input shaft seal. It is not
that hard to do.

Another leaky source might be the oil cooler seals.

You might get by with just tightening it up a little.

You will need a 13 mm 45 degree offset wrench to reach the bottom two
nuts unless you want to go the long route of removing the inlet
manifold, pulley tin, and left upper tinware.


This works for me!
