Why can't you sell the customer what they want and leave the mistakes to them?
You are a salesman. Your job is to sell parts, not correct your customers.
You are not a doctor, not a pharmacist, you sell parts. So, sell parts and stop whining about your customers on-line?

You're right Zuki. I shouldn't even try to help, just let my customers try to do things that won't work - or even do things that are flat out dangerous.
I can't tell you how many times I've refused to sell compression fittings to repair rusted brake lines. It's an accident waiting to happen, and I don't want me or my family to be the ones hit by a brakeless vehicle. But, if it's my karma to suffer from other's mistakes, maybe I should suck it up.
I've meet three people in the last five years burned from tossing gasoline on a smouldering brush fire. I should start supporting those who suggest it. Maybe Darwin was right.
Even the little stuff - like converting from OBDII to a carburetor just so the owner won't have to learn about fuel injection. It's not my problem if it won't pass state inspection - I've mentioned that here more than once. I'll stop.
Passing along the right information would just stop most postings, too. After all, if the kid wants a body lift kit for his Cherokee, we should just suggest how to stack the factory cab isolators for the same effect. Longer bolts? Aisle 3A.
Zuk, I sure hope your counterman isn't reading this thread.

Here's another one - lady calls and wants a PCV for her import SUV. I need to know which engine - they are both similar, V-6's - and she explains her check engine light was on. She called her "mechanic," who told her over the phone that all she needed to do was change the PCV, as that was what the trouble was.
He could read the codes over the phone for a non-electric part with no sensor?
I suggest the PCV could simply be cleaned with carb spray - which she had - and as long as it rattled when shaken, it was working.
Maybe we should start a thread on "mechanics," or those who think they are - but I understand folks who get those phone calls are often just trying to go along with what the customer wants . . .
