Distributor O-ring
To All:
The neck of the VW distributor is fitted with an O-ring. It fits in a groove about two-tenths of an inch wide located about three-quarters of an inch up from the bottom of the neck. A new O-ring usta be included in every overhaul gasket set but it could also be purchased individually, back in the days when.... whatever. So why mention something that's found on every VW distributor? Based on comments received in response to my post about the distributor's need for lubrication, it appears that some folks are running distributors that are missing their O-ring and they've confused its groove with an oil channel. (One guy swore he'd NEVER seen a distributor fitted with an O-ring... about three breaths after telling me what a great mechanic he was, how many engines he's built, etc. and so forth.) Oiling groove goes up & down. O-ring groove groove goes roundy-round. -Bob Hoover PS -- You can't use just any O-ring. The O-ring for the VW distributor has an oval cross-section. And before you decide you can do without it, since you have been... like that 'unnecessary' thermostat or the air-dams that vanished from the underside of your heads nine overhauls ago, keep in mind that the distributor's O-ring not only serves to keep the oil in, it keeps contaminants out. -- rsh |

Could be he's only ever seen distributors which have been in the engine for so long that the O-ring has been crudded up with sufficient crap that the shaft looks continuous. Or maybe he wouldn't know the difference between an O-ring and a sphincter ring.... As long as we're on the topic of distributor lubrication, this might be a good time to mention the felt plug which hides under the rotor in the distributor shaft. It's supposed to get the occasional drop of oil to keep the centrifugal advance mechanism happy, IIRC. If that many people are running without O-rings, then odds are there are as many running without the felt plug. |
