If your just using oil it's probably not the problem, but it is something to be aware of. most of the time a slow loss of oil in an older car is not worth fixing, and is the result of age worn piston rings and or valve guides. Even if it's not smoking it doesn't mean it's not burning it.
Quad 4's were great when they ran but were prone to failure as well. i had one that calved, and have two friends who are looking for them to replace burnt out ones. The junkyards are full of spent Q4's. I wouldn't touch one with a ten foot pole. A Fiero with a v8 would be great, maybe a Northstar engine would fit in their nicely.

I thought it was only the intake manifold gaskets, never heard of a headgasket problem on those. Definitely easier in a grand am than a montana though, a bit more room to work under there.
The Quad 4, yeah. Great that it eventually spawned the Ecotec, and the SCX HO one with the better camshaft's great....buuut not too reliable. Still have a soft-spot for them, as a Beretta GTZ was the first car I've ever been airborne in (as I held on for dear life). Too bad the computer aspect of it may make it tough to get an Ecotec in a Fiero. They're gonna get cheap since they did put a good few of those in later model J-bodies.
