i have a 91 accord lx with 240K miles on it. it still runs good and quiet but i go through oil too fast and i was told that it was the piston rings which is a costly and big job. i was told it is better off just getting a used engine with like 140K on it and have it replaced and replace other parts. i wanted to know if there is a manual that shows the step by step instructions on removing the old engine and installing the other one. my cousin and a friend of his, both well experienced with over 10 years experience non certified mechanics, will do it because honda charges 1200 compared to their 0 because he is my cousin. so i wanted to make sure they were doing it right and that is why i need the maual. any help will ne great. thnx.
