blowing smoke from tail pipe

After replacing turbo in my PT cruiser now it is smoking trouble shot it and found out return oil line was clogged, cleaned it out and reconnected everything. must say that before started project the old turbo shaft was broke in half one in housing and other in exhaust manifold. That being said, replaced with new cartiage and turbo running fine now, but seems to show me another problem which is the smoke coming from tailpipe, then when shut down car I get a puddle of oil water dripping which appears to be coming just before the muffler color looks like coffee and creamer, what could this be, this did not happen before replacing turbo help pleassse
