Yeah I talked to the guy and asked him to check that first before going all in on the manifold he sent me a video of the smoke test and it was coming from all under the manifold from all around it so could that be the bolts?I would definitely get an Harbor Freight torque wrench and make sure all of them are torqued properly. It's like $20 for the 1/4" drive that reads inch/pounds. Much cheaper if that's all it is.
