If you have only used your fingers and haven't tried a wrench on it, I wouldn't think it unreasonable to try to tighten it with a wrench using sensible torque (below bolt spec.). Get a new drain plug, also; it's great for peace of mind to have a spare in the trunk.(and cheap).

If you try to tighten it, you could easily destroy both parts. A tap is the proper tool, if you are convinced the threads are the same. the tap should turn very easily to clean the threads. Significant resistance and you should investigate further before continuing. Above all, do not try to tap incorrect thread pitch to match your plug.

I should add a good tool shop should have thread pitch gauges - can be a very handy item.

Clean the threads with a correct size tap, and put that NEW plug in. You only need to buy the correct size tap, without buying the whole kit.

Thanks for the input guys. I was down by our other MB dealer for lunch (where I bought the pan) and picked up a new pan, gasket and plug. I will try the new plug and if it doesn't work then I will put the new pan in and they will take back the old pan and gasket and credit me. Good thing is I can go home tonight and no matter what get it finished.
Thanks for the input. Randy '94 E500 |
