weird turbo sound?
Hey guys im new to the site I have a 2003 dodge diesel and when I put it to the floor or while pulling I hear a sound coming from exhaust or turbo maybe it sounds like a vaccum cleaner almost (not the normai turbo whistle) ive checked for boost leaks I found a few and fixed them and still no change still hear the vaccum cleaner sound seems a bit doggy to me as well also checked turbo shaft play it is good one guy I talked to said it could be the waste gate but im stumped right now and need so help thanks in advance, mitch

also when im driving normally in lower gears seems to have the normal turbo whistle I more so hear the vaccum cleaner sound when putting it down or pulling so I assum its when its boosting it s kinda hard to explain

Ive checked intercooler,boots,pipe for leaks all good had a quick look of exhaust manifold doesnt apper to be any obvious leaks are you thinking its a boost leak or......

I was also wonderimg if it could be a map sensor issue or something along those lines

no it sounds more like a vaccum seems to be more so coming out my exhaust I was towing camper this weeked all seemed ok then today on the way back I heard the vaccum cleaner type sound and truck seemed to be unpowered pulling the trailer im kinda wondering if my waste gate is sticking open or if I have a bad map sensor or something seems to be intermintent im not much of a diesel mechanic so im kinda stumped here

X2. Mine gets loud when I pull my travel trailer. Its also intermitent, especially when going up grades.
Have you noticed a rise in EGTs (higher than normal)? Increase in black smoke? (also thinking WG issue)

no its not the fan I am aware of the sound of the engine fan this like I said sounds more like a vaccum cleaner out my exhaust and seems to be underpowered when it happens I don't notice any smoke out exhaust just the strange sound and a lack of power is there a way to check or test the waste gate?

You can actuate the rod by hand or use compressed air to the actuator. You can also unhook the actuator rod from the gate and work the gate by hand to see if it sticks.
