Geek With Attitude
Now I realize I'm only a mechanic, and not an Ivy League scholar, and I may not qualify as the next inductee into MENSA, but I'm still a pretty smart guy. Oh, I may not know all there is to know about every single make and model out there, but I have enough background and technical ability to solve just about anything that goes wrong with the modern car. But, for some people the mere thought that a mechanic might actually have a few brain cells just baffles them to no end.
A few weeks ago I got a call from a guy, who (to the best of my dim witted abilities could tell), was having a problem with his truck. He told me that he pulled all the fuses, and was still having a battery drain issue he couldn't find. He even took it to another shop and wasn't happy with their results, so he was going to give me a chance at it based on a friend's recommendation.
"Bring it in tomorrow, and I'll get it checked out for you," I told him.
The next day a 98 Nissan pickup with 150,000 miles on the odometer was waiting for me. After getting the owner's information, I went over what he wanted me to do. Little did I know this guy had all the answers already. Not only the answers, but several ideas as to what was causing his problem. This particular guy was a full-fledged computer geek with more than a little attitude to go along with it. Not only did he think he was dead right about everything, but that every mechanic out there was nothing more than a knuckle dragging grease monkey with the IQ of a walnut. The more he told me about the problem the more I knew I was in for a long afternoon. Seems everything that was ever wrong with the car from the day he bought it was leading up to the moment the battery went dead. But, of course, it's not dead now... that takes a month before it would happen.
"A month?" I asked.
Oh, he had an answer for that too. It all started with the front crankshaft seal. The seal was leaking, and it leaked all over the alternator, so he had the seal changed along with a new alternator and battery. (Both the alternator and the battery came from one of those cheapo depot places; imagine where the seal came from.) A month went by before the car wouldn't start again. The seal was leaking too, but not nearly as bad.
"Hmm," I said, sitting at the service counter thinking this whole thing through, "You say it takes a month before it won't start? Are you driving it much?"
"Yes," he said, "Every day."
This didn't add up, something else is wrong with the car. As I tried to explain to him that if a car is driven every day, and starts perfectly fine,but then all of a sudden it goes "click-click" it tells me there is something else wrong, and it's probably not a battery drain issue.
"Leave it with me, and I'll check it out," I told him,
Apparently, Mr. Geekdumb doesn't have a clue how a car works, other than where to put the gas and which way the key turns. Not that I'd hold that against him, a lot of people don't know a thing about their transportation. It's just that most people don't try to sound like they do, especially while standing in front of somebody that just might.
Once I had the truck in the shop it turned out to be a classic problem; the battery bolts were tightened down as far as they could go, but I could easily pull the cables off the battery without any effort at all. The charge output and parasitic draw tests showed no signs of any problems. As for the seal leak. Well, if you've been around cars with high miles and poor maintenance you've probably seen this before. The PCV valve was clogged. Without that, no ventilation for the lower end, and of course, a back pressure builds up and that pressure has to go somewhere... usually out a seal, and the front seal is one of the usual places for it to go.
Explaining all this to the computer nerd turned out to be a whole lot tougher than I thought possible. How one person can act and think that they are so smart, but can't see the logic behind the explanation is beyond me. The more I tried to explain, the more this guy asked even more bizarre questions.
I gave him the run down on the battery clamp issues, "Yes, a loose battery clamp can make the car not start. Sometimes you'll get one quick turn of the starter then nothing, not even a dome light. Other times you'll get a "click" which is what your car sounds like. This can also stop or restrict the alternator charge output from entering the battery."
"So, that's why my dash lights don't work?"he asked.
"There's no relationship between the charge output and the dash lights. That's a separate problem. Most likely the rheostat," I said.
"Well, what about the switch on my dome light, it doesn't work. I'm positive that is due to the front seal and the PVC you mentioned."
"Sir, it's a PCV not PVC, "Positive Crankcase Ventilation" is what it stands for, and no, it has nothing to do with your dome light."
"So I have two PCV's in the car?"
"No, just one."
"So where's the PVC?"
"That would be in your house most likely. Most homes have PVC plastic piping."
"So, now you're telling me I don't have two PCV's?"
"I never said you had two."
This went on, and on. My frustration level was getting to my MAX level, and I'm about to tell this guy just where he can put his PCV and his PVC. But, after lengthy deliberations he eventually decided to have me at least fix something...one thing…change the battery clamps. He had the solution for the dash lights, dome light, PCV, and the front seal. I apparently don't understand,or fail to comprehend how all his other problems are related to the dead battery.
He showed up later that day to pay for the clamp replacement, and it wasn't hard to tell this guy had an ego driven "micro"chip on his shoulder. He wasn't about to have some lowlife mechanic explain the physics of the internal combustion engine to such an astute individual as himself.
His parting comments as he walked out the door said it all.
"I work on highly technical and advanced systems on home and business computers that are far above the complexities of anything you'll ever see. I'm better off fixing my own car, because I have a degree, and my intelligence level is far superior than any mechanic."
Really? That's the best you got?
Better luck insulting me next time, fella…leaving is probably the smartest thing you've done so far… don't let the door hit ya on the way out.
