I have an 04 with 80k miles on it and it is whistling from the coolant resevoir cap (I think).
The truck got an SCT with Innovative's X race tune at about
30k miles. At about 40k I was getting some serious puking and had ARP Studs intalled with and egr
block off plate. At 75k, just prior to my 2nd factory turbo locking up, I started hearing a very strange whistling noise coming from under the hood. I thought it was the soon to be dead turbo crying out for help. My boost gauge would show 50 PSI
at the end of third gear at WOT
. I installed a VGTSR and on my road test I heard this noise again. Took it to a freind (Ford Diesel Tech) that did the studs for me, and he told me the noise was coming from my resevoir cap. He said that my head studs were likely leaking again. I have had to add a little bit of coolant over time, but I never noticed any puking. My freind told me to get the heads fixed again and "get a smaller damn tune"
Has anyone else had this problem?
Has anyone successfully retorqued head studs?
Is this tune making my truck eat turbos?
Does the 50 PSI
sound possible or sound like a gauge problem?
Any other thoughts are appreciated
