Anyone experiencing problems with these motors going bad prematurely?
I have a 2003 Monte Carlo SS that would run out of oil to were the light would come on when it was a year old.(bought it new)
At 130,000 & 9yrs old I had a motor put in because something to do with intake, antifreeze,and motor getting ruined….
I’ve heard of others with same motor in a Grand Prix having the same thing wrong & Chevy won’t recall.

Quoted From Trcustoms719:
A lot of these engines went bad because of their lower intake manifold gasket problems..

Yep, the lower intake manifold gaskets are a known problem with those engines (as well as the 2.8, 3.1 and 3.4 engines). It’s not too terrible to replace that gasket, but it is time consuming. Just make sure that you use Fel-Pro Perma-Dry gaskets, rather than the gaskets that you can get from the dealer. I had a customer with a 3.1 powered Malibu insist on using GM parts, and it came back leaking about a year later. I replaced the leaking gasket with Fel-Pro gaskets and it hasn’t leaked since, and that was 4 years ago when I replaced it the second time.
