I'm going to to show you a simple way to help increase your engine and manual transmission life by magnetizing the drainbolt.
Step 1: Gather your materials.
Drain bolt from your oil pan
Super glue - Make sure you get a super glue rated for metal and magnets. Krazy glue does have a product that will bond metal extremely well.
small neodymium magnet (I used 8mm x 3mm magnets)
Sand paper or steel wool
Degreaser (You can use dish soap in a pinch)
Step 2: DISCLAIMER
Try this on a lawnmower or small engine first. Make sure you have this working well before you do this on your several thousand dollar car.
I take no responsibility if your bolt comes apart.
Step 3: Clean the Drain bolt.
Dry the drain bolt so that there is no solvent or moisture on the drainbolt.
Step 4: Add some glue to the drainbolt
Step 5: Position the magnet
Let the glue dry and cure for a few hours. then attempt to move the bolt with a screwdriver using light to moderate force. If this holds, then your okay.
