I honestly don’t like doing any job in which theowner or customer has done damage to the engine due to street racing or doing things they shouldnt be doing to an engine. I dixed one guys 1998 Trans AM LS1. He busted a push rod and I replaced it at well below what iw oul charge other people due to him being a good friend. 2 weeks later,he brought it to me again. He told me he was again racing. I opened up the valve covers and found not only was another rod broken, but the 2 rocker arms had broken as well. Idk if Im willing to fix it a third time if it happens again. 😛
