need help oil leak and noise in rear cam area
 

2005 A8L 4.2 i have an oil leak does anyone know the best way to find it, and im also hearing a loud kinda chain rubbing coming from rear cam compartment

If it's petrol as I don't know much about diesels, then the rear cam noise will be a chain tensioner which was relatively easy to change on my previous V8.

Re oil leak you will have to be more specific.

Can you specify in your signature if it's TDi or petrol.

i bought the car from an auction it had front end damage i put in a radiator,fan,condenserand hood. its petrol. bc the tensioner is bad will that make it stutter upon accelerating.. when i accelerate its stutters at first but once im moving its good until i slow down. now with the oil leak i see a lot of oil down by the serpentine belt.
