I have been reading the posts about vacuum pump failure and the related bad things that can happen. It seems that there are early and late style pumps with the later ones having the caged bearings{good}.
My 85 300TDT has 312K miles on it and I bought it from the original owner, so I have every maintenace record since the first oil change. I went through the 2" stack of receipts and found nothing on the vacuum pump ever being replaced. How do I tell if I have the ticking time bomb pump or a good one. Dont want any catastrophic engine failures as this car is in really nice shape.
Thanks
