its only a matter of time before that head gasket starts to leak! Reusing those torque to yields!!!!!!! what an idiot! they are going to back themselves out lil by lil! what did that save him 15-20 bucks? if even that much! If you are ever forced to reuse torque to yields I learned you should put a little bitty dab of locktite at the top of the threads as close to the bolt head as possible. In fact if you do ever do that, put your drop of locktite on the bolt, lay it on your work bench and let it sit for a few minutes that way the locktite dries a bit and doesnt want to run down the threads. It will help stop them from backing their way out. Either way, it's a frickin daewoo!!!!!!!
