Re: 3.8 liter Ford V6 Engine
About 20 years ago, I was in a position where I had to drive a good distance to work, and so I purchased a little imported ford, that got terrific milage with it's front wheel drive little four. But it burned a little oil, so I decided to put a set of rings in it, and do a valve job. I had the official ford service manual, and having pulled the engine, when finished and reinstalling the engine, the manual stated in no event ever reuse the bolts (I do not recall, but I think there were four of them), that bolt the engine to the transaxle. So I went to my friendly ford dealer (small town, I knew everyone there), where I had purchased the vehicle, to get the new bolts. Parts manager said they did not have them, I asked if they could order them, he said yes but I would have to get a dozen of them, because that was the minimum he could order, and they were priced out of sight.

I asked what they did when they serviced this engine, and he said he did not know, so I went to the service manager whom I knew well, reached up on the top of his desk, got his copy of the service manual, and turned to the correct page, showed him where it states, never, ever, reuse these bolts replace with new, and asked him what they did when they worked on this engine, (it was very easy to remove, and no room to work on it without removal). "Oh golly, I don't know" he said "I guess we use the old ones, and put locktight on them". Oh well, it figures, like they say take it to the dealer, they know their product.
