    New member need advice.Took 2008 Limited 4.7 110k to Toyota dealer for P1442 code, they replaced both switching valves, car seemed fine, after I stopped for gas and started engine, a terrible knocking,rattling sound came from engine, like marbles in a bucket. Shut down , towed to dealer, they claimed carbon debris in #8 cylinder, they removed. Picked up car, now have a knocking sound in engine, on that side. Engine was pefect before this, synthetic since new, change every 5k. Dealer acknowledges knock, claims not their fault, want big bucks for tear down. Anyone ever encounter this. Frustrated in Ohio
