I had a fun experience this week trying to find an oil pressure sender replacement locally. On the cross-parts reference, a Volvo part is listed. So I called a Volvo dealership and asked them to send me the part, well, they said it was replaced with a newer part and could overnight it to me for free, so I purchased it for about $30. It wasn't even close. Wrong size threads, and had a spring loaded piston on it. So, I would like to warn everyone else that the part number in the cross reference list is wrong and won't thread into your block. I called up about 4 Volvo dealerships here in Central PA asking for help, and when I mentioned it was for a PRV-6, the answer was either "that engine was used in boats," or "i have no idea." I would have thought Volvo dealership mechanics would have known a thing or two about the engine??? This was kind of scary, considering I may need to call one of these places in the future, should my D ever need some serious engine work. I'll deal with that when it comes I guess. Anyway, I looked back in the backissues and found where Marty Maier specified the Autozone part, Wells PS-136. I was able to cross reference this part at NAPA and the price was around $27 with tax. It looks almost exactly like the original, with the exception that there is a spade connector at the top instead of a bolt and nut. Matt #1604 P.S. Does anyone have any good tips for restoring the black plastic valences? Mine are a little scratched up.
