Yep had mine bout that long too-NO its not for sale---one more thing remember to RESET TO ZERO the % gauge before you go do the next cylinder( part of the attach/ unattach/attach tap the lense LIGHTLY routine---REPEATABILITY is what counts here---this is not rocket science merely comparing one cylinder to another looking/hearing for wear or malfunctions/damage---we always leak a new engine before start up/after initial start up to get a baseline for the future to see how much wear we really are getting as we put runs on the car--but we do leak it at the end of EVERY day racing just to see whats going on-FED387

It's also good to check for leaks with the piston all the way down (with rockers backed off). Just a little more information.

Good day, can a leak down test be done on a cold engine?
