The 1995 6.5td is complex.After replacing the IP,the turbo,injector,the truck still smoke black & no power.Nice idle but lots of smoke in acceleration & no power.28hg vacuum pump,15hg at wastegate actuator.
MY question:where the wastegate rod should be at idle?If I hold it to the firewall I notice less smoke.if I hold it to the front engine,lots of smoke.the actuator pull the rod to the front of engine but does not push back to the firewall,is it normal?I do not know how to check the boost.Should the actuator have a spring loaded to close the wastegate?
