I recently bought a 2010 ford sho that had a broken front turbo, i bought two cr engineering upgraded turbos. I also removed all three cats and resonator, the only problem iam having is when i get on it and once i release the gas pedal and start to decel it smoke blue and i can smell oil burning and see it at the stop light then it goes away, at idle it doesn't smoke but if iam in park and bring the rpms up to 2500 and hold it for a few minutes then the smoke comes out. I looks like the previous owner has already replaced the rear valve cover and pvc with the canister, in need of help? also the compression was good as well.
