After lettin my 7 sit for a bit over a week under a tarp and car cover in my driveway, i popped my hood to show it off to my friend and i found this gross white stuff formed in little clumbs on my alternator. It looks liek some sort of calcium deposit or something like that....It had been raining liek a ***** all that week so the moistuer i assume caused it...it had no oder, so whats that sound like? anythign worth worrying about? it wasnt on anythign else but the alternator
