We recently had to do a head job on a 2009 Chevy Aveo. The guy never changed his timing belt and ended up bending ALL of the valves when the belt stripped out. We got it all done and back together and now we keep getting a engine code saying theres a correlation problem between the crankshaft and camshafts. I have taken it all back apart 3 additional times after the head was fixed trying to get this straightened out and I am stuck here. Are there any relearn procedures for the Variable Cams? It seems that the phasers/solenoids might keep throwing the exhaust cam out of time? Any help would be greatly appreciated! If you would like to call me my phone number is (517) 442-2054.
