Metal in oil filter
you are right, there is some noise cold until engine warms up.
once warm it sounds good.
i usually change oil between 2500 -3000 miles and the oil is never black. It gets dark but nowhere near car oil after 5000 miles.
Without the cleanable oil filter I wouldnt even be thinking about this.
just that pinch of yuck making me sweat a bit.
dont know if crank has shifted. No new vibrations and pressure is right where its been for life of the bike.
ill drain the sump this weekend and see whats doing but salt is on the roads now so Ill likely pull at least the cam chest down.
maybe Ive just got a lifter flaking or cam loosing finish.
wont be able to sleep at night if I dont know
these screens have been around for eons of time and are heavily used in the industrial world but they have a dark side, they accelerate wear. another feature is that as wear increases so does the need to service more. we had them and with monitoring systems, truth told, the factory filters out performed them but then again 70>90 bucks each and 7 to a pot. pay me now or pay me later. we wound up installing centrifuges if screens were used.
i will never use one that is for sure.
the metal was in fact magnetic.
i found a very small amount in sump, I mean very very small amount. Not enough to even notice unless you have 10x magnifiers on and a really bright light.
I did find more of it in my rocker boxes ( more the front than the back. Again, not much but Im looking very very closely.
Ive pulled the whole camchest (pump, lifters everything).
Absolutely no strange wear on anything except the pump rotors. They are within spec but very obviously had something go through (back rotor has a gouge that you can see and barely catch with fingernail.
strange thing is one of the chain tensioners (outer) is missing its internal spring. Dont know how the hell that happened. Dont see a way for it to escape into oil.
was expecting to see a lot of runout on crank.
well 0.001 in cases. Shocked. Absolutely shocked. I have ridden this thing hard so that makes me happy.
My working theory is this
About 2500 miles ago I installed high ratio rockers (screaming eagle) the rub surfaces are broke in now but not excessive. I suspect the magnetic material I found in filter, rocker boxes and small amount in sump is wear/casting flash off of the new rockers.
shame on me for not cleaning them better before install.
unless I come up with a better theory Im going to replace pump rotors and both tensioners.
clean clean clean and re-assemble and flush with several oil changes in a row ( like back to back to back idling in garage).
any thoughts?

So if the magnet falls off, or some clown pulls it off and sticks it back on, all the crap that was there will be released.
You don`t need a magnet if you have an oil filter.
