I have to admit the thought of performing a compression test was akin to thinking about writing code or rebuilding a laboratory instrument. Neither of which is something taken lightly; however, thanks to the wonderful people on YouTube I was able to purchase a kit for under $50 and get this task accomplished. My son and I worked through checking each of the four cylinders in no time and he even mentioned being able to assist his friends in the near future as they are all at that age where their driving permits are burning a hole in their wallets.
I will add some videos on how to check the compression in general and one of us checking the 1995 Nissan Hardbody ourselves.
