Folks,


Just about to do a gearbox oil change on my 07 STi. Understand it has two drain plugs. Do either or both have crush washers to be replaced? If so, anyone know what size?


Thanks.

I've never replaced the ones on mine , would say it be better too though but I've never had a leak from either of the plugs done this with all my previous subarus.

 

You just re-used the existing ones?

 

Yeh i have always just re used them never leaked i would have replaced them though if i could have got new ones but they are copper so I'm sure they can be re used unlike the crush ones in the engine sump that has to be replaced every time .

 

Okay, will do the same.

 

I have always replaced mine.
