My father and uncle owned a repair shop in NC in the late 40s to mid 50s. He taught me well. He lost money and eventually his shop because he was a Tucker automobile investor in that post war period. He taught me to work with my hands and my mind. I’ve worked in the car industry for two periods. During my early college years 1972-75 then after my oil career from the late 80s until now. I’ve learned a few things over the years. There are people who take your advice when they ask you for an opinion and then some don’t want to believe you because they are just stubborn. I lately dealt with both.
This weekend I had a mechanic for Ohio Edison ask me about the check engine light on his daughter’s car a turbo 1.4L Chevy Cruze. He had 4 OBD-II codes. They all pointed towards electrical issues. I told him a few tips to diagnose the car and that it was probably a bad valve cover throwing codes because of either an air leak or bad PCV passage.
There is another customer with the same model car and issues who first took his car to a local national parts store . The counter guy who isn’t around that model car every day told this other guy that his 11 codes were a bad computer. The mechanic took my advice the other guy took the parts stores diagnosis. They both come to me frequently and the one guy spent way too much money because in this one case he refused to listen to me. He didn’t bring the car to our shop for the computer replacement, was very pissed at the other shop, the car and somewhat at me for some unknown reason. It was his choice to not listen to what I said. I sell 4-5 valve covers for turbo 1.4L engines a week. Its so common there are Youtubes and forum stories about this problem.
Don’t ask me for a cure if you are already set in your mind as to what you think will fix the car. Don’t ask me for my knowledge if you are going to get mad at me when you don’t use it. I’ve known both guys for 15-25 yrs and have never misdirected either. Now I’m directing the one to talk directly to the service department.
