Ive had this happen on 300s, but never on a V8.
Every 4 or 500 miles ill start hearing a whistle in the cab, its done this for a while now, and the one nut on the back passenger side of the carb would be loose, causeing a pretty hefty vaccuum leak.
Well last time i rebuilt the carb i put lock washers on, and now, after about 1000 miles i heard the whistle again, i thought "it cant be that carb again, i put lockwashers on", so i searched and searched, thought it was in the HVAC shit behind the dash.
Then it kelt getting louder and louder. So finally i checked the carb and every damn nut was a good 3-4 turns loose.
What is causing this? Im thinking about trying nylon stop nuts if it continues, but id like to find the root cause. Bad nuts? Bad studs? Its driving me nuts.
Btw its a bone stock 77 F250 with a 400 and 2150 2bbl.
