I wanted to pick your minds on this.

Well... a friend came over and told me their sister's car wasn't working right. Then they followed by saying they had just gotten a new engine from... let's call it hypothetically, Big S Tires. Instantly I cringed. Everybody I know has a story about Big S Tires ripping them off. Or some other mechanic. And when I told them this they were like, oh its a good engine, I swear by it my friend's dad works there he wouldn't rip us off. And I'm thinking, OK did you just not notice that your car is still broken when they supposedly fixed it? I tried to tell them but anyway they don't listen.

Anyway, frustrating to see this. I was trying to help them but it wasn't my car. But I had a story where a different shop I had them fix a broken window and they told me a 6 dollar part was a hundred dollars. Only problem with that story is he forgot to take the part invoice from their parts supplier off the desk as he's telling me that. So I can literally see the 6 dollars there when he went to the back.

Just about everyone I know has a story with mechanics ripping them off. And from many places not just one.

So what I wanted to ask was... say you take your car in and get them to swap out the engine with something else... how would you verify that they really swapped it out instead of just cleaning and detailing the engine instead? I'm pretty sure this has been done to people a bunch. And when you have your engine cleaned and detailed it CAN really look different. Makes you wonder doesn't it?

...

Note that 25 years ago I did have a Japanese engine exchange and it was amazing. But that was before things got more corrupt.
 
If I needed someone to paint my house, fix my plumbing, or change car engines, I would ask in our hometown Facebook group for recommendations. People there will be brutally honest.

There's also something I've never used called Angie's List.

Thank you.
 
Engine blocks are stamped with serial numbers. Look up where it stamped online and check the numbers. The factory engine will be stamped with a number that aligns with the VIN of the car (thats where the term matching numbers on old collector cars comes from).

It's also not just the engine block. The tranmission and rearend are also stamped with the last numbers of the VIN from the car it came from.
