A simple and inexpensive part that will help keep your mind at rest with your 86; Mishimoto's magnetic drain plug.
Bearing damage is a concern on any high performance/track car and installing a magnetic drain plug is a cheap way to keep tabs on your engine. For a DIY'er, this will allow him/her to monitor any metallics in the oil pan.
This drain plug is a direct replacement of the factory unit (24mm hex head - M16x1.5) and is constructed of billet 6061 aluminum. The magnet provides enough strength to collect bearing material or other harmful metallic fragments in your engine oil completely removing them from circulation. Again, another inexpensive way to make your 86 more reliable.
