Drain Plug New Oil Seal

[flynrider]

I have reused the washer many, many times on my bikes before replacing it - probably at least six reuses, and the engine has never leaked a drop.

My CB750 still has its original washer at 43K miles. I inspect it at every oil change and it always looks good. If it ever looks deformed or leaks, I'll replace it. Until then, why bother?

Note : One thing I'm very cautious about is not over torquing the drain plug, which likely keeps the washer from deforming. I helped a friend replace his pan once after he got a little carried away while tightening the plug. Not fun.
