Ok so i went to go pick up my civic from the tuners today and was told that my rings need replacing before taking it anywhere close to 20psi

Only rebuilt my motor roughly 20 thou ago. The previous tune must have chewed them up over a year. So i mean i've stopped mechanics working on my car for over 3 years now. I've done everything myself, building turbo kits, removing the motor, changing clutches, suspension work, wiring. Pretty much everything bar from Tuning a car (which should always be left to someone who has had experience) and cracking apart the motor.

Do you guys think its a possibility to replace the rings myself. My unk has an engine rebuilding shop so i will take it to him if i get stuck. But i would like to do it myself. I have the tools and the shed space and i will get some advice off him but i just wanted to know cos a few people on here would have done it.

Also what would be rough time it would take to complete by myself? I know theres ways of getting around it by not taking out the whole motor and just removing the bottom end and doing it that way. What would be the easiest way?
