regarding my ??? about turbos

If the wastegate "is " jammed in the open position will it cause the noise/symptoms I described?---also when you idle the truck the noise is still audible but not as noisy as when you run the engine up to 2000RPM----It appears to have a 1/8 inch line going from a fitting in the front of the engine to the actuator head? and if I disconnect it you are telling me I should be able to move the rod/wastegate fairly easily correct ??? Should I lube the wastegate area/shaft whatever with say heat riser lube to free it and maybe try working it back and forth??? Will that help any???? Do not want to get into pulling the turbo if I do not have to not a lot of room to get at it plus disconnecting all of the exhaust and intercooler stuff only to find its the wastgate or its linkage---Thanx for the advice guys Comp 387
