recently for past month my 6.5 has been shaking and smoking white really bad on start up. i replaced glowplugs and gp selinoid about 2 weeks ago. the smoke doesnt smell like coollant. i can shut it off at a drivethrew(to hear them) and it wont smoke but like 15 min shut off or more it will smoke and act up i also replaced fuel filter and oil and filter like 3 weeks ago. i read on this problem and it could either be coolant,oil cdr, injectors or timing i read that my year had bad problem with #8 cylinder getting a pin hole in them so when the motor cools the hole expands and the coolant if has any pressure backs into motor. and if it helps any the only code im getting is 32 which is egr circuit fault. it also spudders when i push the the pedal to the floor. its really agrovating

 

Sounds like a leaky injector to me

 

Anyone know how to test it?
