Oil was oil when i drained it and changed the crank seal and the orange o-ring was there.
could be that rtv stuff. Probably just freaked when i saw the orange bits and had the orange o-ring in a box next to me.
So, i changed the oil pan gasket on my brat and noticed a orange o-ring in pieces there. I assume it's the same as in this pic.
Now the question, where's it from and how hard is it to put a new one?
I tried looking from exploded view thingys but couldn't find it.
