Hey Guys, Gave up on the engine swap in the DeVille. To many Headaches on that. So I going to see what the HT4100 can do. I thought I would start with a duel exhaust system. So I figure I might as well replace the manifold gaskets while I was at it, This is where it gets fun. I pull out the Haynes manual an it states I have to DROP the subframe to remove the rear manifold. This is a joke right? Had to be written by someone having a bad day? Anyone done this on a 85 Sedan DeVille (tranverse mounted engine) I sure would like to meet the idiot who laid out this set-up. It's one thing to mount a oil filter upside down on top of the engine, But drop the subframe to replace a gasket?? Good thing I love this car.
