So sad, man. RIP that 3800. I would not even crack open the engine any further, its time to replace. Happy hunting up another in your area. I'd be curious what you end up paying for a salvage engine, if thats the path you take on this.
All Grand Prix, all the time. 69 Model J, 99 GT & GTP coupes. All junk, haha.
