Making your own gasket was a common practice back in the day, but it’s a DIY skill that is slowly dying off. With that said, this is still a trick that you should know because as a car builder, eventually you will run into a situation where this option could really save your butt. In the case of our K-swapped Integra, we had fabbed-up a block-off plate for some extra ports on the throttle body and needed a gasket to create an air-tight seal. Knowing that nobody makes such an animal, we headed to our local parts store to get a roll of gasket material. On the way back, we also stopped off at Michael’s, to pick up a special tool. The skill we are about to show you is pretty much a no-brainer. Any idiot with a pair of scissors can pull it off (no offense Yamz) but choosing the right tools for the job can make the difference between a good result and a poor one. The other part that takes a brain is knowing when to apply this practice. For instance, building your own head gasket is probably not a good idea. Don’t forget to use a little common sense.
