I'll cross my fingers the diagnosis requires a new crate motor :P

Must be nice having that fancy warranty.

Ouch. That'* going to hurt. At least the misfire was a easy fix.

but 1200 for cooler lines!!?!?!?!?!??!?!?!

how much do they cost down there?

That'* a lot for a cooler line. Personally I would get generic hose that is rated for oil and use hose clamps. Unless it'* leaking at the flare, in that case I would buy flare tools and make my own. But that'* just me.

how hard is it to do it myself at home? any idea?

I've never looked at a N*, perhaps venom could shed some light on this.

John where are you!? lol

Can you see where it'* leaking oil? The N* is not my area, I know very little about them. Make sure anything you do will not effect the warrinty.

if i do i'll be using GM parts for sure, they are not really that expensive its just labour that is stupid expensive.

i have no idea, i was told its leaking by the guy who did my oil change

I suggest looking yourself. I have a link to GM parts, I'll have to post it when I get home.
