Loud blowing noise
I just bought a 97 7.3. This is my first diesel so I don't know much about them yet. I've driven te truck for about a week and last night on the way home from dinner I noticed the motor/turbo making a loud hissing noise. Not like the usual sound. Louder than that and it sounds like air is being blown out of a shop hose. It will make that noise while cruising but as soon as I get on it a little the noise will stop. Also if I'm in park and rev it up to about 1500 rpm it will bog itself down and make the noise again. Any suggestions?
