Can some please tell me what the actual size in mm for Oil tank drain plug seal washer is. I think I may have over tightened the plug and split the washer on my last oil change about 3000 km ago, it is now leaking.

I need to get one in a hurry as I'm going on a drive day.

TIA
Jim

 

It seems l jumped the gun and panicked but l might have under tightened it as is was quite easy to tighten a bit more with ease. I'll know in the morning.

 

For reference just in case

Oil Drain Plug (22 X 27 X 1.5 mm) washer = 900-123-118-30-M131

Oil Reservoir Drain Plug (20 X 24 X 1.5 mm) washer = 900-123-010-20-M131

Turbo Oil Reservoir (18 X 22 mm)= 900-123-140-30-M17

 

reference those part # on koperformance.com you can buy all the seals for pennies vs the dealer cost

 

Thanks
So the opening is 18mm, is that correct?

Thank you guys

After tightening the plug with same washer it seems to have stopped leaking.
The local hardware store has them for next to nothing but have to go by sizing and not part numbers.

 

The case drain plug is 22mm, the tank drain plug is 20mm and the turbo drain plugs are 18mm on the ID.

Those numbers above are I.D. x O.D. x Thickness

And I'm with you on sourcing them locally, I just saved the part numbers with the dimensions when I researched them.

 

Use torque wrench.. Always!
