Thanks Benzmac. The sprocket, cam, chain, chain rail, tensioner, cylinder head etc. were all replaced 2 years ago.... Turbo has never needed repair so with 320k miles, the wastegate might just be the problem.

You could have one or more problems. You could have a fault with the waste gate, Or you might just need some adjustment or a timing chain and sprocket. Have it checked by a knowledgeable tech.
