Well, I totally butchered removing the Bank 2 A/F sensor on my 99 Avy. Replaced the less accessible Bank 1 twice without problems but Bank 2 is original and it seems like it is welded in there. Anyhow, the only chance I have at this point is to remove the exhaust manifold to get better access. Fortunately there is a flange separating the manifold from the exhaust. This flange has studs with what appears to be male Torx ends. Looks like you remove the nuts on the exhaust side and then unscrew the studs. The studs screw Into the flange on the engine side. I believe you have to remove the studs in order to have enough play to remove the manifold but I could be wrong. When you remove the 5 nuts holding the manifold onto the engine, I do not think you have enough play to pull it away from the engine far enough to clear the engine studs unless you have the flange studs removed.
Has anyone ever removd the exhaust manifold on a 3.0 V6 1 MZFE engine? Any tips? Thanks.
