[DML] Re: Fuel distributor o-rings

["Delorean3760" <Delorean3760@xxxxxxx>]

David- I could not agree more, I thought the same exact thing when I was having all problems (It has to be installation damage) I recall trying several O-ring lubricants, short of KY jelly, and I would still after a week or so have a rest pressure issue.  I wondered if there was a metal burr or something causing the damage.  Never found out what it was, I was using Special T O-rings and they seemed to be fine out of the package.  They were even fine when I removed them, less the chunk missing.  Baffled me, still baffles me.  Seems like if they are the correct size, once installed on the PPR, it should just thread in.

> My guess about chunks missing from "O" rings would be most damage to "O" rings, besides age, is directly caused by installation. A tougher materiel would be more resistant to installation damage but still not impervious. You must lubricate the "O" ring and the bore before installation and if it does not assemble smoothly the "O" ring should be removed and inspected for damage. If the "O" ring is not exactly the correct size then that can also contribute to installation damage. Obviously "O" ring damage is not a common problem unless the PPR has been disassembled or we would be seeing a lot more cars with pressure problems. There are a lot of Deloreans out there with original units that have never had their PPR's touched and are working just fine. For further information there is a lot of stuff available about this subject all over the Internet. Start with "O" ring manufacturers and their advice on installation procedures and fitting of the correct size "O" rings and how to handle them. NASA learned how critical handling "O" rings can be!!!!
