I am about to put a vortech on my 96 w/ 86k miles. I wanted to make sure my rings and valves etc. are good so I did a dry compression test. They ranged from 175-180 w/ the exception of one cylinder ( second cylinder from the firewall on the drivers side) that I tested twice and it only made 165 PSI. What does this mean? Should I be worried? Should I still put the vortech on or is there some other tests?
Thanks
