H3lly Posted September 21, 2010 Share Posted September 21, 2010 There is no way to be sure unless you get it scanned. It could be the idle valve or a vacuum leak. Quote Link to comment Share on other sites More sharing options...
kcboy Posted September 21, 2010 Author Share Posted September 21, 2010 Well the two big pipes that run into the intercooler have oil on them and one pipe has a little slit in it, do you think this could be the problem, its a loud nosie aswell thanks Quote Link to comment Share on other sites More sharing options...
alz Posted September 21, 2010 Share Posted September 21, 2010 welcome kcboy, you need to replace the split pipe before you start looking any where else on the car. Quote Link to comment Share on other sites More sharing options...
mintalkin Posted September 21, 2010 Share Posted September 21, 2010 i would say the split intercooler hose is your problem, its a common fault on the diesels. Quote Link to comment Share on other sites More sharing options...
