you did-it-Yourself

Parts, tools and materials needed:

  1. 10 Quarts of your selected oil (Porsche recommends Mobil 1 - viscosities vary according to climate)


• Oil Filter Element - OEM comes with O-ring (996.107.225.53)

• New Aluminum Crush Ring (900.123.106.30)

• Spent oil collection container (make sure it has enough capacity to contain at least 10 quarts)

• 8 mm hex wrench with ratchet or 8 mm Allen Wrench

• Filter Element Wrench (74/76 mm)

• It is good to keep a new oil pan plug as a spare (900.219.009.30)

The above parts and part numbers are good for all Boxster/Cayman models and model years.

Because I do so many oil changes I decided to hack a special and easy collection unit.

I used a 5 gallon bucket (with blue lid),

a large Funnel, a piece of chicken-wire

mesh and a piece (12”) of 1/2” diameter

clear tubing.

You can purchase a 5 gallon pail with a

snap-on lid at Home Depot or similar for

under $5.00.

The funnel fits in the lid’s opening.  If there

is no opening, then make one large enough

for the funnel.

Thread the clear tubing through the funnel

secure the top with a zip-tie.  You’ll need to

make two small holes for the zip-tie.

This is needed so that the funnel can

“breathe” while the oil is being drained which

allows for a free flow into the bucket with

no overflow.

Cut a piece of chicken-wire mesh so that

it fits snugly on the upper part of the funnel

about 2” from the top.  This will save the oil

pan plug from clogging the funnel or falling

into the bucket.

Remove the oil cap and set it aside.

This will speed up the draining oil.

Raise the car on a lift, on ramps or on sturdy stands.

You will need access to the area under the car between the rear wheels.

Find the aluminum oil drain plug in the center of the oil pan and place your collection container underneath.

Oil flows best when thoroughly warm (hot), so make provisions to protect your arms and hands by wearing gloves and having towels handy to quickly pick up any spills.

Using the 8mm wrench, loosen the aluminum

drain plug.

It is easier to “crack” loose the plug with the

ratchet and then removing the 8mm wrench

from the ratchet, and finishing by hand.

Once the oil has finished draining, replace the aluminum plug.  Don’t forget to use a new crush ring.

This will ensure a tight seal without any oil leaks.

Now you can focus your attention on the Oil Filter.

Using the 74/76 mm wrench

loosen the oil filter cartridge.

Once it’s loose, place the oil

collecting container under it.

You can now probably finish

removing by hand.

You can now tug down on the used filter element to remove from the engine.

Inspect the element and the canister to make sure that there are no metal flakes or particles.

Remove the O-ring on the oil canister.  Pry it off using a flat screwdriver and pull off.

Clean the canister using a paper towel.

Clean the groove that holds the O-ring

Install the new (supplied) O-ring in place

Drop the new oil filter element in the canister.

Dip the tip of your finger in the collected oil and

lubricate the new O-ring.

Screw in the canister with filter element by hand.  Make sure you don’t cross-thread.

Tighten as much as you can by hand then ...

... tighten 1/4 turn with

the wrench. 

That’ll get you very close to the recommended torque values.

Below are recommended tightening torque values.

                                 Oil drain plug to oil pan... 37 ft-lb (50 Nm)

                                 Oil filter housing to crankcase ... 19 ft-lb (25 Nm)

By the way, if you ever noticed the black plastic grommet on the trunk lid and wondered what it was for...

Now carefully pour in 9 qts.

of your selected oil.

Turn on the engine and wait for the oil lamp to go off. 

This fills the filter canister with oil. 

Turn off the engine.

Wait a minute or so and check the level.

Note older Boxsters have digital gauge as well as a dip stick, but newer ones and Caymans only have the digital gauge.

Add more oil if necessary, but

don’t overfill, so add just a bit

at a time and measure again.

When you’ve reached the full level, replace the oil cap, and you’re done.

Happy Boxstering,
