Odd sound under load
I have a 91 f150 4.9 5 speed. Under load it makes a wooshing sound like an exhaust leak, but it stops when i shift up a gear and starts again about ten seconds under load again. Odd part is that it does not do this all the time. seems like a valve opening and closing any ideas. Also i need a new shifter boot where do I find one thanks

IOW, if you do hear it with the fan on High, and don't with it off, then that's what it is.
Just one possibility to explore--good luck.

mine did that also, i though it was something in the vacuum system.
as for the shift boot, the OE one was alot. i think over $150. so i picked up some hot rod one from autozone for $15 and put it in. it worked, looked OK up close, better from a distance.
this is the first fit. after this i took it off, made it level, polished it up and put it all back.
