I've just have to pull my upper manifold (if that's the piece with two runners and the throttle body mating surface) to replace my fuel injectors. I'll touch on why I had to do that in another thread to help anyone else with a similar problem. But while I was removing the upper intake, I realized they were all FINGER tight! Whoever serviced these injectors didn't re-torque the upper manifold bolts after letting them warm up and cool down! I want to make sure that when it all goes together, both of the intake pieces are torqued properly. As well, I'd like to know if I should replace the upper manifold gaskets if they aren't damaged. Are they generally reusable? How do I find the darn things??
