I had a Volvo with the PRV engine back in the late 70's and if I remember right it had close to 150,000 miles on it (including replacement of the camshafts twice) before I got rid of it. I was stopped once in my -87 Volvo (probaly in 1991or so) by a friendly "Smokie" in Montana who told me had had a Volvo/PRV since new and it had 800,000 miles, including several rebuilds by himself, before he junked it because the body and frame had completely rusted out beyond repair. Must have been a glutton for punishment, or maybe he had been smoking something funny? Does anybody know the design history of the PRV?
