Seriously, a $14 cap......or is it?
I'll try to make this quick. I have an '04 F250 6.0 4x4 with A/T. Mods include AFE Proguard 7 OEM replacement filter, 4" turbo-back exhaust, and an Edge Juice with Attitude.
A couple of weeks ago, I started hearing a loud whistle (not the normal turbo spooling). It occured on acceleration, constant load, and after letting off the throttle. On Saturday I noticed 2 decent sized pools of coolant under my truck. I have never added a drop since the day I brought it home new, but I added just over a gallon. My commute to work is 30 miles of Interstate. Over the last 2 days I have been checking my level on arrival, and I have already dropped to the min mark from the max. My engine temps have not exceeded 180 (I live in Colorado where it hasn't been to warm lately). This morning, I saw steam coming from under the degas bottle cap. So I had an idea.....I traded my cap for one of our work truck's as a test for the night. The loud whistle is gone and not a drop of coolant under the hood tonight!
So my question is: Do you think the cap will solve my problems? Or is there a bigger problem that hasn't fully surfaced yet? Any thoughts/things to look for would be a great help. Thanks in advance.
