Repair kit thread oil drain plug


Oil pans in modern engines are almost always made of aluminum alloys - they are light, corrosion-resistant and a good heat conductor. However, oil change intervals have become longer and longer in recent decades and the oil drain plug is made of steel. A not too uncommon consequence is that the contact corrosion between the light metal and the screw can progress between intervals to such an extent that parts of the internal thread of the oil pan corrode onto the screw and tear out. As long as it is only one or two threads, it is not a problem.

At some point, only a small amount of thread is left and it cracks long before the prescribed torque of the drain plug is reached. Then good advice is expensive, there is no thread left in the oil pan.

Replacing the oil pan is time-consuming and the new oil pan is quite expensive.

We have a solution that is as inexpensive as it is sustainable:

A drain plug that is one millimeter larger and the corresponding tap with the same pitch. This allows the oil pan to stay in place and enables a quick repair. Due to the small difference in diameter, no additional pre-drilling is required.

A tip from us: Grease the tap well and cut in stages, then most of the chips will stick to the tap and you can always wipe them off in between. Any residue remaining in the tray can simply be rinsed out with a little fresh engine oil.

The drain plug is supplied with two sealing rings:

  • an aluminum ring for aluminum oil pans
  • a copper ring for steel oil pans

Never use the copper ring on aluminum oil pans, as it accelerates corrosion due to the material contact.

The repair kit is now available in our store under the number 1091197.
