Found this while changing my oil pan gasket

seestheday
It was time to change my oil so I put in 5 oz's of seaform and took the bike around the block (neighbours would not like it running in my driveway for 5 min after 10pm).

After I drained the oil and removed the filter I decided to also change the oil pan gasket as I suspected that it was leaking and that now was as good a time as any to do it.  Getting all of the old gasket off took a lot longer than I thought it would.  I used a gasket scraper, and next time I think I'll find some chemicals to make the job a lot easier.

Anyways, here are some pics of what I found in the oil pan.

Bits of gasket material and aluminium:


What might be what's left of an o-ring?  Hopefully just some gasket sealer that peeled off.


A pic of just the aluminium.


I'm guessing that the aluminium that I found is the remnants of the mess I described on this thread: http://honda-cb750-s.456789.n3.nabble.com/Heli-coil-Timesert-question-td3931333.html#a3936251

I'm hoping that it's not something more serious, but I guess there is no way to know until I pull the engine apart.

Re: Found this while changing my oil pan gasket

I'm assuming I'm going to need to pull the oil pan again.  Now that I've done it, I will have an easier time with it.  Based on how much I ride it I won't need an oil change until I put it in storage for the winter.

Can I re-use the gasket or do those need to be replaced each time?

Are you sure it's aluminum?

I thought the internals were ferrous hence why we install magnetic drainplugs?

I often reuse a gasket, if it is still in good shape. Sometimes I will smear a very thin layer of Black silicone on the gasket side that goes towards the engine,

Pretty sure it was aluminum. I think it is the part of my engine head that broke off when the valve cover threads broke (see link in original post).
