I think passages are the same. I also think many people who experience lubrication problems simply failed to change their oil regularly. I believe this is part right and part wrong. After my first change of the camshafts the Volvo dealer service manager (a real pro, honest, but subsequently fired) told me that I HAD to change the oil every 3,000 miles -- in spite of the fact that the owners manual called for 5,000 mile oil changes. I am sure it was coincidental, but the new camshafts lasted exactly 2984 miles before the cam lobes went out again. I still have the receipts to prove it! Both the dealer, the Volvo District Rep and their US HQ in Englewood, NJ refused to pay for the second replacement. I refused to drive the car out of the dealership lot and as a result it sat there for 5 months. In the meantime, while I was on a trip to Sweden I called an old college buddy who had been the service manager at Volvo North America for 3-4 years. He gave me another name to call and after I had told that guy the story he told me n ot to worry and gave me another name to call in NJ after I got back home. I did after I returned home and a few days later my PRV engine had new camshafts -- at no cost to me. During the discussions in Gothenburg I was told that there had been three changes since the introduction of the PRV engine: The heat treatment of the original camshafts had been too soft, the oil pump had been changed to one with a higher flow rate and some of the oil gelleys had been changed to better lubricate the cam lobes. This is all history and should be of no concern to a Delorean owner. Imagine my chagrin when I was negotiating the purchase of my Delorean about 3 years ago and saw a Volvo PRV engine under the hood! I was "stuck" on the car but sure as heck not on the engine, so I posted a message here about my concerns. I don't recall exactly how many responses I had, but everyone essentially said the same; that although they had heard about the early Volvo/PRV problems, they had been fixed before the first engines were delivered to DMC. I bought it and have been happy with it ever since -- except for the damned water pump/distribution design, but that is another story!
