Hoping someone with more experience knows what to look for here.
Last Feb I replaced my turbo, didn't get a chance to change the oil line so it had a slow leak, finally got around to replacing that, however to get the gasket remnants off, I attempted to rotate the turbo, should have just pulled it off instead. One of the bolts snapped. not a warranty-able item so I paid the shop I bought it from to fix it (drill/re-tap) During this process, I changed the exhaust manifold gaskets because one of them was leaking.
After all of this, I suddenly had a howl at 2-6psi... thought it may be the exhaust touching the frame, so when it was in for other service, I had them bump it over while they were under the truck. Didn't drive much since with all of the weather... but the other day I drove it, and not only do I have the same howl from 2-4psi, but at around 3 psi and 1400 RPM I get what sounds like when we were kids and put an index card in the spokes on our bicycles...
Of course my exhaust has that Cummins fart sound of a straight pipe but never heard these howls and fan-ish sounds before getting those exhaust manifold gaskets done... are these just normal sounds that I'm only now hearing because of the increased flow?
