Ive never had a 5.7 diesel but Ive read about them. I guess there was a problem with the head gasket needing to be replaced every few years. Anotehr reason for the bad reputation was it was a smaller engine made for economy not power. Retards would buy it because its a diesel thinking diesel means lots of power like a semi truck and over work the little monster. Im not saying was a great engine but Ive talked to guys who did like them but they said you had to take it easy.Fuller Johnson;1569611; said:Oh Really.... How Come it didn't hold up then.... ????
