6.4l powerstroke started up at store yesterday and it started making this really loud whistling noise drove it 20 mi to garage and they couldnt figure where its coming from I drive about a hundred miles a day to work hauling a 20ft 8000 lb trailer,is there concerns I should worry about till I can get it to a real diesel mac
You may have a crack in the intake. Is it an air whistle or a whine whistle sound?
Inspect the downpipe connection. It could be a cracked bellow.
check you CAC air hoses and connections. You may get lucky and it just be that one came loose.
nope garage says 2 broken bolts on exhaust manifold and three stainless filters 2300 dollars
3 stainless filters? What are those?
Perhaps one diesel exhaust particulate filter and two stainless steel band clamps.
