...she started fine and idles alright but I got smoke coming from under my cover platethat seprates the exhaust manifold from the FI injectors near the rear of the engine. The wastegate sits right next to it so my guess is it could be a faulty pressure control line or possibly an oil line. definately not gas or antifreeze. Also my oil line Pt# 035 145 735 is nasty looking with rust and weeping oil all over the back of the oil cooler tray and AC compressor. Any thing i need to know before i change it?
