Not sure if anyone has a lot of experience with the GM 3800 and w-bodies... I’m pretty sure I’ve got a cracked rear manifold, and I’m working on a replacement. I’m in the process of a LIM gasket, so I’m thinking about doing it now. I know a lot of people like to drop the subframe a few inches and take it out the bottom, but I’m working in a stall with a pit, and I have nothing to support the motor with, so that’s not an option for me. I’d rather not go that path anyway... I don’t want to mess with that. Im trying to estimate how difficult it’ll be to do from the top while I have the blower and rear valve cover off, the dog bones out, and the motor strapped forward. I’m not that worried about the LIM gasket, it’s just this exhaust manifold I’m stressing over.
