With a crush washer?I bought one of the magnetic plugs from--I believe--Whitehorse Press. My drips about ten drops of oil after being ridden. I assume the difference in cooling rates of the cases and the plug account for this. Not a big deal --especially if you're used to riding an old BMW...
I always find a little of what you describe. Maybe clutch plate material, don't know. I wouldn't be concerned unless you find shavings or chunks.Just changed oil the other day and there was a fair amount of crap adhered to my magnetic plug. It was grey-ish. Hmmmm, should I worry??
Hear, hear. Since I did strip my drain plug. Tapped it out and all is well with a little teflon tape. The teflon tape is dope. I just barely snug it and never a drop.Something that needs to emphasized-
Never over-torque the drain plug. If you're using a crush washer and it leaks, either live with it or refresh the crush washer. Resist the temptation to tweak it a bit more to see if it stops leaking.
The drain plug is easy to strip and, once stripped, is a Very Bad Thing (tm).
