I had an almost bad experience today with my 1987  Vanagon's oil plug.

I had taken it to where I usually take my van for repairs and oil changes. In a short while they came and told me that when they went to replace the oil plug, the plug stripped out in the bottom of the engine. I really do not understand this as I have never had any problems with the plug. they said that since that plug has been taken out so many times, that because it is aluminum, and the plug is steel that some times they will strip out the threads. 

To fix it, they were able to put in an over sized "Piggy back" oil  plug. It seems to be ding fine but, am just wondering if any one else has ever had this type of problem as I have been on this list several years but, have never heard it mentioned here before.

Thanks for any ones opinion on this.
