Next on the list was I after a under bonnet inspection I spotted the all the back of the valve cover was pissing oil out. Turned out all the valve cover fasteners were all nealy fully unwound of the studs, so after cleaning up the mess there isn't and more leaks. Touch wood. Also been busy I've had the exhaust manifold off and I give it a light port, I got most of the restriction out the carbide bits all lost there bite and I was fed up with the air tools give me shite so I called it a day and chucked it back on. With that all said and done I think now I can feel the fuel pump suffering with these cold mornings and less resistive manifold
