Some background.
2.6 V6, 106K
When I bought the car, the areas in the photos where there is now oil, just had black grease which had collected over time.
The car was owned by a mechanic who worked at a garage that specialise cam belt changes. Apparently the cam belt and tensioner was changed along with the rocker gaskets withing the last 10k.
When I tried to remove the old oil filter without success, oil appeared from around the filter housing, which I expected because I had interfered with it. Also under the filter, dripping from the crossmember and also at the front area under the pulleys, gathering on the shelf area above the sump.
I have converted the filter to a spin on and there is no oil from there now. At the same time I cleaned off all the oily areas.....front, crossmember, engine side etc.
Now the front area and crossmember drip with oil, it's clean oil and I am filling with a litre after 3 or 4, 15 miles trips to town and home. The area in front of the engine had been completely cleaned as well and looks like the oil is spraying onto it.
I had filled the engine with 5W 30 for a short period before changing the filter, then I have used 10w 40 from Vauxhall.
Pictures follow to help you see what I see.
