Okay I finally did it!!! after 12 years my PRV finally saw the roar of life again. We were able to get this beast running on the bench for several minutes!! Okay so there were a few vacume leaks. None the less a 12 year old engine with umm... all kinds of "stuff" inside the motor. Did turn over on my test bench roar to life and run for several minutes. we also smoked up the shop pretty good, lol. The PRV is in amazing shape for 12 years of neglect. Once I tear the motor all the way down and replace like everything lol. I'm not sure what I'll do with it at that point. But now we know it worth tearing down. Todd Vin5386
