Check out the various posts, but I'm pointing you to post 305. Start from the beginning, its a pretty informative thread.

I guess there are alot of people with the same problem as me. I have a 2005 g35 6mt. Spoke with the mechanics at infinti and already went through the whole ordeal of doing that stupid oil test after 1000k . Brought back my car and they found out that there was something wrong with my engine (duh) they told they would change out the whole engine , which they only change out the small block....is this all they need the change??? is there anthing else that could be damaged?? anyway i got my car back and everything feels like new....engine sound like a champ hopefully it wont happen again. Do you think i could of claim this under the lemon law??? or do i have to give them 3 chances to fix the problem before i can claim it under the lemon law?
