Well, my mom's bf hyrdolocked my engine. We did a compression test and it failed miserably on a dry test. On a wet test however, it had perfect compression numbers. So I know I need new piston rings. Does anyone know how much it'll cost to have new rings put in? Also, who here besides me thinks that more stuff is hurting besides the piston rings? He said that he was going really slowly when he hydrolocked it, but still... dumbass was trying to compress water with a mechanical device... This is after I told him not to drive it in the rain. Would you guys say that the labor for the piston rings would be over a 1000? Over 2000? What else might be broken?
