Re: new here need some advice
1999-2002 would be a 3.1 in the 'Bu, a 3.4 in the Alero and Grand Am.
The 3.4 is a bored and/or stroked 3.1, or the 3.1 is de-whichever (I don't remember which one changed, but one did between them).
They can and quite often do (aftermarket!) use the same gaskets.
Both have the same generic problems with lower intake manifold gaskets.
This is NOT a 100% faillure item, now! Don't misunderstand me! It's just that these are more prone to wearing out than I personally think they should have been.
The 'Bu and Cutlass are also prone to the A/C control head failing - there's links here on how to repair the head, so that's not a major problem.
They're all prone to the ignition switch itself failing, and due to how they're located, it's usually more labor effective to swap both the switch and the lock cylinder at the same time.
Overall, they're nice cars - build quality is better than a lot of the older GMs had, but not as good as we may have come to expect from new cars.
335K miles on original motor and tranny (only motor work 2 x LIM replacement), Monroe SensaTrac struts front and back (new at approx. 300K miles), and Alero discs in back. LS fogs added with custom wiring. HID high beams, HIR low and halogen fogs. Raybestos Pro Grade front rotors and Bendix D747 ceramic pads on front.
Addendum: Rest in peace. Surge tank blew, motor overheated, I think she's lived a long and useful life.
