Hi, I did an oil change over the weekend, but prior to commencing, I noticed a possible oil leak on the side of the Engine. Doing a search on here led me to this : Engine & Gearbox - 2.2 i-CTDi Oil at Side of Engine A bit more investigation reveals possible another leak further on towards the front near the pulley. I have attached pictures below and circled areas of interest in red. Car has done 79k at present. Couple of questions : 1) Do I need to drain the oil before I redo the gasket on the inspection cover in Pic3 below 2) I am assuming the leak from the pulley is from the crankshaft seal - is this a garage only job - as I don't have access to any ramps? If so what sort of approx of cost would I be looking at? 3) Is it worth changing the serpentine belt (I think thats the correct name?) - it look ok, but I guess if pully is coming off it would make sense? Thanks in advance.
