As the title says, even after a short drive I'll check the bolt and it will be loose, even if I just tightened it down. So the options I can think of are either put a lock washer on it, put locktite on it, or chase the threads with a tap. I don't think the locktite will hold up to the heat, but I guess it couldn't hurt to try. What do you guys suggest? Thanks

I did properly torque it, it vibrates loose everytime. I'll try out the lock washer and loctite though. Going to order a new turbonetics manifold today

+3 for the studs/nuts/lock washers
theyre 8mm studs, you can get them at a good hardware store, just make sure theyre heat treated. or like ^^ said, the stock 4g63 manifold studs work great.
