Automotive help please?

I have 2 Questions- Number one is what would be a likely cause of a slow oil leak? about once every week and a half or 2 weeks i have to put a quart in, or the engine starts knocking. I was thinking it could be the valve cover gasket, but i just wanted a second opinion





Number two- How difficult is it to replace a power steering pump and reservoir? The car is an 89 Grand prix. I have a fair amount of automotive ability, but i don't claim to be an expert by any means. I feel like i should be capable of changing the power steering pump, because i can't imagine that there's a whole lot too it, But i just want to make sure of what im getting into before i start ripping parts off of my car haha. So if someone can please tell me what all is involved in power steering pump replacement, i would greatly appreciate it. Thanks!Automotive help please?oil leak some are visible you just have to look around or maby your burning it a slight ring problem changing your plugs will show in burning
