Place some cardboard and an appropriate sized oil catch under the engine oil sump drain. I use a antifreeze jug with the front cut out.

Loosen/remove the oil dip stick...

Use a 19 mm wrench to loosen the engine oil sump drain plug. I prefer to use a 6 pt. 19 mm socket for all the drain plugs.

Remove the engine sump drain plug and allow the oil to drain fully into the catch.

Note the engine oil color, black.

This is normal metallic swarf on the drain plug magnet.

Heavier or larger particles favor impending timing gear tower failure and needs further investigation.

Clean the magnet off with a clean rag and once the oil is finished draining, re-install the engine sump drain plug.

Slide the oil catch up under the front of the engine. Use a 22 mm wrench to loosen the oil filter base plate. Again, I prefer to use a 22 mm socket and ratchet.

Unscrew the oil filter base plate...

...and remove the plate and oil filter.

Careful as the filter and base plate will hold residual oil.

Remove the old oil filter.

Use caution as the rubber seal (seen on the base plate boss for the filter) may remain with the oil filter. Do not throw this seal out with the old filter!

A side view of the rubber seal on the base plate boss.

Never mess with the by-pass valve located on the side of the base plate. It looks like a screw. It is pre-set at the factory to 10-13 p.s.i./0.07-0.09 MPa.  If you play with it, you'll have to figure out how to re-set it.

Remove the seal and insert it into the bottom of the new oil filter.

The base plate acts as a catch for metal debris that comes off the timing gear tower and internals of the engine. Flush this area clean with solvent before installing the new oil filter.

Use caution when using EMGO brand filters. The EMGO hole for the rubber seal is smaller. DO NOT FORCE THE EMGO OIL FILTER ON the base plate or you will split the rubber seal. I do not like the EMGO filter in its present form.

Use a 19 mm wrench to loosen the oil filler plug of the gear box...

...remove it...

...put it somewhere where it will not get lost...like on top of the foot shifter.

Use a 19 mm wrench to loosen the gear box oil sump drain plug.

It is located aft and above the engine oil sump.

Remove the gear box oil sump drain plug and clean it off.

Note the color of the gear box oil, honey colored.
