I'd forgotten about that Lumina Z34. I hated that car. The combination of the "Monte Carlo wannabe" and the go fast decals turned me off to the car. Up until the latest GM 3.6 DOHC engine, I think GM's best V6 was the 3800 series engine. My mom had a 90s model Oldsmobile Delta 88 Royale with that engine. It wasn't the supercharged version. That thing was smooth, had plenty of pickup, loved the open highway, and was bullet proof reliable. Such a shame they couldn't continue to improve that lovely engine.
I have a '93 Olds Cutlass Supreme. It's in the shop now, so I can't remember if it has a 3.1 or 3.4L V-6.
Anyways, are these one of the worst engines from GM? I haven't talked to anyone that has one that didn't leak a ton of oil - mine leaks about a quart of oil every ~250 miles/1 week. Because of the way the engine is placed, it's actually more cost effective to just keep putting oil in it than spending $800+ to get it fixed.
Now, I'm leaking water and coolant like crazy. It's coming from the intake manifold, so it's too expensive to fix ($1,000). I only paid $1,300 for the car back in 2000! I think it's getting time to give this car to my brother since he can actually fix it himself and use it.
Anyone else have a similar model or experience?
I thought the 3.1's were really good motors but I've heard there were alot of reliability issues on the 3.4's

That seems to be the general experience. My sis has a 3.1 in her Century, it leaks some oil and is dirty, but it has been a reliable if not inspiring performer.
i have a 1990 GPT v-6 z24 turbo,i just bought ,the previous owner that owned it since 1993,tells me oil somehow every once in a whike gets passed a seak it the turbo and blows out smoke is this correct about a seal needing replaced n the turbo?
Yep, my 2003 Malibu had the intake problem. GM knew about the problem and did not correct the problem. It began leaking after the factory warranty so they didn't care. There's a new gasket, bolts, and torque specs that's suppose to correct the problem.

My sister had a 2001 Malibu. Her intake gaskets went, which also messed up the cat converter, which made the car run really rich which messed up the O2 sensor. That thing was a hot mess, it was like a chain reaction. Luckily her's was under warranty.

Ummm, what is a 1990 GPT V-6 Z24 turbo? A Z24 is a Chevy Cavalier with a 3.1L V6 and it did not come with a turbo from factory.

There is no Grand Prix Z24. A Z24 was a Cavalier.
The Grand Prix Turbo was a 3.1L V6 turbo and only 2000 were made for MYs '89 and '90, but it was not badged as a "Z24."
The turbo seals on such an old car could very easily be a problem.
I have a 94 Camero with a 3.4. I cannot find a replacement front crankshaft sensor GM PN 10137663. It's been discontinued and it seems no one has a replacement part to replace the faulty one. Any help out there?
