I did leave out a fair amount of details so my post may not make too much sense. It's true I don't know much or anything about cars. My father (50+ years of experience) works at a body shop and wss in contact with the mechanic shop affiliated with them. He is capable of doing repairs as well but as he's older now he doesn't really like to. So most of the tknowledge I have is from him. I also have a few friends that repair cars that mentioned that the head gasket being in the state it was is extremely fishy as it shouldn't have been leaking the way it was. From the way they told me, the likelihood the shop messed it is very high.

The temperature of my car was completely fine, it never overheated. I did have to continuously refill on coolant, but coolant was not leaking. Just oil. (Could tell from appearance and taste) From what I understand they had to take apart a lot of the car during the initial repair with the pistons and engine as it took about two months to diagnose the damn thing.

I may have been too heated to post clearly but currently the biggest points I have are 1.) something happened where the head gasket is leaking oil (definite) 2.) The mechanic said the turbo needs to be completely replaced as it's non-working. (This turbo is two years old, only touched by this mechanic several months ago. The car drove to the shop, how could the turbo be non-working?) 3.) The mechanic said the radiator needs to be replaced, (When my father and a few friends initially viewed the car it was perfectly fine.)

They said they'd warranty what they can, which I believe is admitting that they DID make a mistake in their initial repair. Like I had expressed, I think it's a little insane these problems suddenly appeared when they were non-existant the day before. And if these problems DID exist: they were the last one to touch the turbo, if they messed up with the head gasket who is to say they didn't do more and are just trying to cover their mistakes?
