Hi first time on hear for a long time been reading a few posts and seem like 'T' is the one to talk to so recently got a doblo 1.9 jtd 2004 82,000 miles on it it has back pressure out the dip stick also hard cold starting there is diesel leaking from injectors/ injector pipes but always drive totaly fine. I was driver back from scotland yesterday and heard a strange wering noise and then turbo died so no powere either i was thinking back pressure was caused by a blocked oil breather or feed to turbo which hac caused turbo to go ?? Really unsure tbh please help

Can anyone shed some light on the matter ? Or can anyone tell me if an alfa 156 1.9 jtd 115 bhp engine code 937a2000 will fit ?
