Looking to pick up a 2004 SLS. Former Deville owner
I recently sold my 1993 Deville..LOVED the car but i got a good offer and parted with it. So i see this really nice 2004 Seville SLS and being a former 4.9 owner...I have been scared off by horror stories of head gasket failures in N* engines, despite them being terrific in every other way. But this particular Seville is nice and just over 100k on it.
So i do a little online research and i am to understand that GM improved the N* issues with head gaskets by 2004.
So my question is : "Is it true the later N* engines are a little further removed from being prone to head gasket failure" ?

You could option some stuff from 2000-on, but I don't know the details or numbers of the stock floorplan trim packages - there were 3 (??) trim levels for STS. About the only way to tell would be to find a 2004 SLS and plug the VIN into www.compnine.com - IF they still add the entire SLS RPO list AFTER the build list for the VIN entered.
Nuts - Looks like CompNine has closed the one-time-free decoder entry.
