Starting from the beginning, a few weeks back I was doing about 60-70 mph the heating stopped working and sudden lose of oil pressure. When I pulled over there was smoke everywhere and oil all over the right side of the rear engine and under the car. I had it towed home and after some research we figured out the oil air separated had fail sending oil through the engine. We have replaced the parts cleaned the oil as best we could. Changed oil filter an o-ring and filled with new oil. When topping up the water/coolant it has stated leaking from the underside of the left monifold (hope this makes sense) and is pouring out. I can't find anything online to say why hope someone can help only had it a week when it happened.
Many thanks
