I'm a noob on nitro engines. I know that a nitro engine's life is very short. Dependent how you abuse it. Lets say, after 8gal. If your engine has no compression anymore and fails many times. Can you then just replace these =>



After you have installed these, is your engine then as good as new and have to be breaked in again? Or do you have to replace the whole (expensive)engine? I can't also find these parts for the .28engine!
