Help identifying mystery engine part
Discussion
I am half way through fixing my brother's Peugeot 306 (1.8 16v) engine. One of the core plugs in the cylinder head opened up a big hole and started leaking a lot of water. I have taken the head off to access the plug and am waiting for parts.
When I was looking into the engine bay after the head was removed I noticed this little green plastic part lying in there. It looks like a one way valve - there is a ball bearing at one end held in place with a weak spring. There is a rubber seal at the other end. The part was oily.
I've got no idea where it goes and, despite looking at all the bits I took off, cannot find a suitable looking home for it. Can anyone point me in the right direction please?
Cheers....

It's a valid question. Firstly, I didn't know the state of the head after it dropped the coolant out on the motorway. Thankfully it is straight and doesn't need to be skimmed.
Also, the car was towed to my parents who are 250 miles away from me. I popped up last weekend to take a look and made the diagnosis. There isn't the space at their house to store an engine out of the car and I didn't have the time/parts to finish the job over the weekend so decided to whip the head off. The head is currently in the loft with the other bits and pieces. The car is parked on the drive to minimise disruption to my parents (I put some oil into the cylinders to stop the pistons seizing/rusting). It's going to be some weeks before I get the time to go back up there to finish the job off.

Yes - the offending core plug was in the head, between the exhaust ports of cylinders #2 & 3. Helpfully, Peugeot installed this engine sloping back towards the car so I couldn't access it from above. Although I could see the plug from underneath (with the exhaust downpipe and manifold removed) I couldn't get any meaningful access as the subframe and steering rack were in the way.
Taking the head off wasn't too bad - the only issue I have is that I can't get the crank pulley off to renew the timing belt. I applied a load of heat to the bolt and my impact wrench (rated at 450Nm) just split the impact socket!
