Hi guys, bought my wagon a couple of months ago, however im just running down my corsa mot before driving it, as its hella fuel efficient and means i can save for undersealing ^^ so the wagon is parked on my drive i get to take it for a spin every two weeks or so round the block to stop the brakes seizing, but ive noticed a near side oil leak, been advised it 'looks' like a rocker and as the engines are flat the oil pools and the seals may have worn or shrivelled, sound about right?
