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 wouldn’t even be thinking about this.
just that pinch of yuck making me sweat a bit.

don’t know if crank has shifted. No new vibrations and pressure is right where its been for life of the bike.
One way to tell if cranks is out of whack is the oil pump loosening up. See how long it takes for oil pressure to come up on a mechanical gauge. If it starts taking longer, the pump has started to loosen up.

Excellent advise. I’ll watch that closely. Ihave a mechanical guage mounted on my rocker box.
Needle is up almost instantly on start up. I’ll keep watching that.

Not a bad idea Kirby.
i’ll drain the sump this weekend and see whats doing but salt is on the roads now so I’ll likely pull at least the cam chest down.
maybe I’ve just got a lifter flaking or cam loosing finish.
won’t be able to sleep at night if I don’t know…

i will never use one that is for sure.
how do reusable oil filters accelerate wear?

Well. Got some time to tear things down.
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 I’m looking very very closely.
I’ve 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. Don’t know how the hell that happened. Don’t 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 I’m 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?

Sounds like a good approach to make a conclusion. Is there anywhere you can attach a magnet to have those magnetic particles glom to and stay in place ? I run with one on the underside of my oil tank (softail) just at the feed side low point. For just in case. I also run the cleanable mesh filter. But not seeing particles in either place.

Filter has a magnet as well as drain plug so I think I’m covered there.

you may want to flush your oil cooler as well. Some say its better to replace but the jury is out. Lifters seem to hold crap in them too.

A magnet on the outside of the oil tank?

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.
