Greetings form Peru justa wan to share my new preservation project with the community. it's a legitimate 1991 OLSDMOBILE CUTLASS SUPREME INTERNATIONAL SERIES COUPE ( X-Code 3.4L DOHC TWIN Dual Cam) with only 25,857 original miles Here is a crazy part of its history: Someone in the past installed a 3rd-generation LPG system on it, which caused it to stop running back in the day. Because of that mistake, the car was left sitting for decades, sleeping like a time capsule! A blessing in disguise for me. Everything from the LPG system has been removed from the engine bay, except for the 16-gallon tank in the trunk and the exterior filler valve, which I will remove and patch later. The great news is that the engine is finally up and running again, and it sounds great! The interior is full Burgundy leather with the premium AQ9 bucket seats, and the green digital cluster works perfectly. Right now, I'm doing a complete brake overhaul (the front calipers were seized) and getting ready for a full fluid flush. New water pump and mechanical thermostat are going in next. My approach is mechanics first: make it move, shift, and brake safely, then deal with the bodywork. Glad to be here, and I'd love to hear your thoughts, technical tips, and recommendations for bringing this 90s unicorn back to life! WhatsApp Video 2026-.mp4 WhatsApp Video 2026-06-28 .mp4

Hi, I have a 92 Chevy Lumina Z34 automatic with the V6 DOHC. It's all stock. I am new to fixing cars and got it a year ago. Any tips or suggestions is appreciated. The current thing I'm working on it wiring and brakes.

Nice to see another Z34 being kept alive. If you’re new to working on cars, I’d focus on getting a solid maintenance baseline before changing anything: fluids, belts, hoses, grounds, and any old or brittle wiring/connectors. Since you’re already into the brakes, I’d check the rubber hoses and hard lines closely too. And if you don’t know when the timing belt was last done on the 3.4 DOHC, that’s definitely something I’d put on the list. Take plenty of photos before unplugging things and tackle one issue at a time. Makes troubleshooting a lot less painful.

Holy Hell...how did I miss this!!!! This is pretty incredible and so glad I finally found this thread. I am here for any help.

I suppose if I were to go the route of a new heart *exotic* transplant the LFX from the Cadillac ATS & the 6T75 trans would be my choice of powerplant. I won't sneeze at a 320 hp na V6.

If I were to guess... the 4T65E in the V8 cars was a pretty tragic weak point so maybe he's tired of cooking those?

The 3.6 is quite an engine. The 6T70E seems to be a pretty-fair transmission, although it pisses me off that there's no serviceable filter. But giving up a V8 in a fairly-rare car to go backwards into ordinary? Re-think this.
