I have an 86 golf diesel with a replaced boneyard pump in it. Can the year of the pump be determined by the part number, or any other means. I mean between 85 to 92. Its one of those years, but its not an Ecodiesel, turbo, or pre 85 pump. Its got the idle speed boost setup on it too. But no detents you can feel when you pull out the timing lever. I don't think 85 had detents ,because the Bentley manual has no idle settings for detents in 85 , but in 86 it does. This would Id the pumpas an 85. But if the detents are wore out, it doesn't. I think they are wore out. The reason I ask is the
85s and 86 have different timing limits. The 85 is 0.90-1.05mm. The 86 is 0.83-0.97mm .I'm at 0.97, which is good for both. The engines are the same except hydraulic/solid lifters, and the extra oil drain passage. But I,m at the upper limit for the 86 , but not the 85. I'm not going to bump the timing back and forth between winter and summer , to boost the power and mileage. So I,m stuck with the factory limits. But I,d like to see if I can cut down the black smoke some. I figure if its got an 85 pump I can bump it up some more without affecting my winter starting. Thanks. Oh yea, I went and drove a new Rabbit today, It was Dark Green with no trim. stickshift, Its pretty sweet. It is pretty much how I like VWs, but I wouldn't want the 2.5L. I may get one when they are 7-10 years old, and use it as a pickup truck. Then again I may wait and get a TDI and use it the same way. I have a lota hope for the new VWs, I hope VW has learned their lessons from their mistakes. Most of you know I rag VW a lot, about their stupid s_ _ _ . But I haven't ragged the new ones yet. Just VWs current business strategies. Thanks Verndiesel- posted
