Just found this?!? What is it from?!?
 

Just found this on my magnetic drain plug. What's snapped inside my engine then.

Valve collet.

You been over reving her m8

Unless dropped during service?

There's £1.86 saved if its a new one. :D

Never seen a collet like that before, been working on landrover and tanks for past 12 years tho. Best check they are all in before next meeting then. But would have thought if 1 had popped the other side would have gone too and dropped a valve. And senna! Com on me over rev, if she has dropped a collet it was probably due to that race, the old girl have you a run for ya money lol.

As soon as you said it was a collet I did exactly this lol

Can't imagine how that got there! Its a half ring that holds a valve in, I would check all your valves, can't see that it got there through an oil way though?

Well it was running fine so can't have been material ;)
