DIY oil change Mezger M64 block engine M96/70 M97/70
For Mezger engines M64 blocks...
Total cost at dealerships ~$150-200.
Total cost of DIY ~$70
Total cost if you or an inexperienced dealership screws things up? How much is the oil tank going for these days? $1444.75, replacement crankcase? $5591.75
Parts and numbers needed:
996 107 225 52(53) oil filter (includes large O-ring)
999 707 465 40 separate smaller O-ring
900 123 010 20 copper ring for the oil tank 44 ft-lb torque
900 123 118 30 aluminum ring for the crankcase 52 ft-lb torque
Tools you'll need after putting your car on ramps, lifts, or stands:
15mm ratchet socket for crankcase drain
19mm ratchet socket for oil tank drain
27mm open ended wrench for counter torque
Oil filter wrench 000 721 920 40
Oil should be changed when the engine has reached normal operating temperature. CAUTION - oil will be hot.
Use a ramp or jack up the vehicle at the correct points.Remove the oil drain screw and collect the engine oil in a disposal container (at least 9 quarts).
Identify the oil tank drain bolt and drain the oil over 20 minutes (44 lb-ft torque.)
Make sure you use a 27mm open ended wrench to counter torque the drain bolt.
Remove the oil filter using wrench and socket:
Next, Remove the filter, old O-ring seals, and replace...moisten the rings with a touch of new motor oil. Reassemble the filter, ring seal, and oil cap. Torque for the oil filter casing is 19 ft-lb.
Finally, identify the crankcase drain bolt and drain the oil over 20 minutes (52 lb-ft torque.)
Once both bolts have drained completely reinstall the bolts with new crush rings, 44 lb-ft torque for the oil tank with the copper crush ring, 52 lb-ft for the crankcase bolt and aluminum crush ring.
Note: 997s VTG turbochargers do not have drain bolts. On 996s, I typically don't bother draining the turbos as the volume is typically quite small.
This technique will require replacing approximately 8 quarts of engine oil.
Good luck.

You don't need a lift, but somehow, you need to be able to get under the car. I used ramps, but you could get away with a jack and stand. Once the car is up, on a scale of 1-10 in difficulty, this is about a 3 (only because you can strip the bolt if you over tighten, or damage the oil tank if you don't counter torque.

Just found this older thread and thanks for posting BBYWU, it'll save me at least $200 when tax is included as dealers here in Los Angeles are charging around $250 plus tax for the oil change.
One question on the oil filter wrench... would using a strap type wrench work or would a Porsche one be needed as there aren't enough room to use anything else?

If you can, get the Porsche oil filter wrench. I didn't have one and I tried literally 6 different types of generic wrenches from 2 different auto supply stores and even the one that eventually worked was not ideal. I now have a scratched up oil filter cap due to all the futzing around trying to get that darned thing off.

I just did my oil today as well! I bought the filter which includes all the crush rings from suncoast! I got the oil from napa and it was on sale for $5.70 a quart!
Oh by the way, thank you Bob for all the help!

+1 as always. I can't imagine what some of us would do without you? Big thanks!

Looking at the tank I would guess it keeps you from bending it out of shape or possibly splitting a weld. It looks like aluminum and could be reasonably soft.

Thats correct...That nut has no purpose except for torquing the bolt...If you don't, you will surely snap the bolt off!
