new noise!

so my 97 f250 7.3/zf5 just made the 6 hour journey to wyoming. ran like a champ all the way here. now when i leave a stoplight or give her a little gas, theres a kind of hissing noise that i hear coming from the engine bay, it does not get louder/faster with more RPMs, but if it rev it and let off it quits, ideas?

and YES i know what a turbo sounds like! haha

Only things I'm coming up with is a boost leak or air intake leak. Is your air filter getting clogged?

my air filter is clean but i was just thinking of that, boost leak being on the y-pipe that goes to each valley and intake leak being the boots pre-turbo correct?

you were correct!, the orange boot that connects the turbo to the cast tube has a tear, after calling around the only place that carries it is fors, i think ill just rip it all out and go AFE. does that sound like a good excuse?

Sounds like a good excuse to add an intercooler.

ok new issue!, put on my AFE this morning, still made the hissing noise, i realized that my oil was about 3k miles old and was just ran 2000-2500 rpm for 6 hours straight, i just did an oil change and the noise seemed to stop, but i noticed that my truck is taking longer to crank now and upon starting it fires then a second time and smoothes to idle. also, i gassed it to turn around in some dirt and when i let off the gas pedal the rmps went way down, almost to dieng, then it caught itself and ran fine. hpop? icp? any ideas? seeing as the OBS uses a heui system thats what i could come up with

What oil did you use? 3000 miles shouldn't be bad on these if you are using the correct oil.

An ICP problem is easy to troubleshoot. Just un-plug the ICP and drive it for a while to see if the problem goes away. Normally, an ICP loses it's seal first. There will be some oil in the plug, or a leak where the ICP goes into the head.

If you have an HPOP problem, there will likely be a HUGE oil leak.
