Okay I thought I posted this question a while back but I can't find it so yet again I'm here asking for assistance I just did my first motor pull and in the process I found countless problems problem one being shaft play on my Turbo 2 being a crack in the exhaust / turbo manifold 3 being the valves on 3 cylinders are white almost oxidation look and one valve is black pretty sure the block came from a junkyard because the paint was stripped it had a layer of rust on the outside and yellow marker writing SRT regardless I have many questions and I would love to hear some answers and opinions like the exhaust manifold I like the cast iron because it can be ported easily and Polished and I'm pretty sure that the turbo is built into the manifold in that case should I get a new Turbo and a stainless manifold I'm not sure what all it will take
