07 psd Intermittent whistle or "tea kettle"

[MDeVoe]

Im having trouble with my new 07 6.0 psd bought used 115k. Im having an Intermittent whistle or "tea kettle" sound varied with RPM and bad mpg. can somebody please help

[devster55]

what are you getting for mpg. and are you talking about the turbo whistle?

Tea kettle noise will most likely bo over-pressurizing of the cooling system and the degas bottle cap venting the pressure. What kind of shape is the oil cooler and egr cooler in?

To check the oil cooler you need to get a data monitor of some sort. I personally like the Edge Insight CTS, but the ScangaugeII is a great option as well. You need to monitor the difference between oil temp and coolant temp. If the oil is hotter by more than 15* then you need a new oil cooler. The coolant loss could be a bad egr cooler or again bad heads or cracked heads.

would a diagnostic computer get me the this info? i added some coolant because my heat wasnt working and was loosing coolant from the degas bottle cap but have not seen any loss in coolant since the past week.

Yep diag tools(scan tools) will give you the necessary readings, but in my opinion you need to have a good data monitor on the truck all the time. Invest in a data monitor
