I have recently had a mechanic change my exhaust manifold as it had cracked and was blowing really bad now that's all ok I have a problem when the engine is up to temperature it sounds like the exhaust is blowing under the bonnet I have had the exhaust checked and have been told that's all ok and not leaking but im thinking it maybe the manifold as the mechanic I used has cut corners putting the manifold in he said he has changed the gaskets but I know he hasn't as I marked the old one and the same mark is there also the washer plate is missing and I now noticed this morning that oil is leaking from the turbo where it joins the pre cat pipe could anyone tell me what this could be as its getting louder and only does it when the engine is hot
