Kosmav Posted November 28, 2015 Share Posted November 28, 2015 Hi all, I have a disco 2 td5 1999 and I am facing a strange situation: when I accelerate more than 2500 rpm the engine starts to "kicking". It happens the same when I kick down... this phenomenon appeared after changing the head gasket. Do you think that those 2 matters are connected?

sierrafery Posted November 29, 2015 Share Posted November 29, 2015 Didn't you unplug accidentally the wategate modulator? ... check the pipes to it to be connected and not leaking, especially the one which goes up to the turbocharger wastegate valve cos that one could have been in the way, or it got hurt when you worked on the head cos that seems classic overboost symptom, it's about this http://www.discovery2.co.uk/wastegate.html Quote Link to comment Share on other sites More sharing options...
