I did not measure the clearance between belt guide and belt. All the pulleys and tensioner were replaced by the dealership.
And I did call the dealership. Their run around is this. the work was done prior to me buying the car as part of the pre-sale repairs; and since They have been bought out by a new company they will not warrantee the work. They tell me there is nothing they can do since they are not waranteeing the old business' clientele.
yes a rod bearing did fail, lost oil pressure and developed a knock.
