Drain Plug New Oil Seal

[Firstfour_imp]

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.

Because it is a 50 cent piece. Negligible in relation to the entirety. Why not just replace the darn thing, rather than hope for no trouble? Seems penny wise... I'll cough it up.

And to each their own, of course.
