My '99 Burb, with the 5.7 liter V8 and 52k miles, has developed an oil leak from the rear of the engine, on the passenger side. The dealer replaced the valve cover gaskets on both sides (it was under warranty) in an attempt to fix it, but it looks like it's still there.
I can't see anything from the topside, but from underneath I can see a thin oil track running down the seam where the tranny meets the engine block. It definitely starts above the crank centerline, but its origin is lost in the darkness above.
The truck is going back to the dealer next week, but I thought maybe the Group might have an answer or suggestion.
Thanks and Happy New Year!
