Very dear, the picture suggests that Your balls are yet to drop, so take a grown up with You.

l could not see ur photos immediately, it took me a while to discover HOW to open them.

l am looking at them now.. it does not look good, wait..
photo 1.. leak around the head of the engine, UK driver is side.
Photo 2. black valve cover can be clearly seen, it is not a leak around the valve cover! (too bad, that is easy to fix)
Photo 3.. again, oil from under the HEAD. And now l see some yellowish, mayonnaise-ish stuff with the black oil. YES?
This indicates ur oil is also mixing with a little water, under the head of the engine.

Sorry, my friend, but this shows me u need a new HEAD GASKET. The gasket is not expensive.40 euro = 25 pounds?? But the labour to put it on is a few hours. You must remove the head. but that requires:
1. drain oil & water. Disconnect battery!
2. remove air cleaner, valve cover, timing belt cover, timing belt, several other little things.
3. LOCK flywheel in place, lock timing gear in place with pins in special holes designed for this.
4. Remove 10 bolts to the head. Rock head gently to break free from gasket. Never pull straight UP.
5. blah blah blah.get a book on the 106.
6. Thoroughly clean the aluminum block surface of old gasket material.
7. Have ur head ''planed'' to perfect flatness by a machine shop.
8. You will need a TORQUE WRENCH (moment spanner? what is that called in the UK?) to tighten all bolts to a maximum tightness all 10 equally.

Are u ready to do the work yourself? IT CAN be done by the average guy in a warm garage in winter. (except for head 'planing'.)
