Firstly, thank you to all that suggested and helped in my previous post. I have now in fact established that the system is electronic not hydraulic as first thought. I have now concluded that I have an engine oil leak but once again I am unable to establish exactly where the leak is. I have enclosed some pics. which I am hoping, may be enough to get some guidance where to start. l advice and suggestions gratefully received. Model : 2014 Rapid 1.2 Eng.No. CBZAF48167 (NH model)

Finding the source can be tricky as you have found out. Oil has a habit of defying the laws of gravity etc. Best option is to clean it up and see if you can trace where its coming from. If its a small area then a can of brake cleaner will do. If its over a bigger area I use Gunk and then power wash. Is it definitly oil and not brake/clutch fluid?

Have a look in the neighbourhood of the throttle body, it may be dripping down the back of the engine from there.

The breather system on the CBZ engines is rather complex and involves several components including a little rubber diaphragm valve in the intake manifold which seems to me to be very likely to clog and stop working as designed. This then means the engine breathing won't work well at idle, causing oil to get where it shouldn't. See my Rescue Roomster thread, page 2.

A simple test of this is with a fully warmed up engine, loosen the oil filler cap to the point it can be lifted away, but don't lift it. See if it tends to be pushed upward, pulled downward or just vibrated a bit in place. It shouldn't be the first of these if the engine breathing is working well.
