Rear main seal

And he didn't help you beyond that point? Oh man. I don't see your problem as being with the seal itself, but with insufficient crankcase breathing. When the pistons are going up and down, the crankcase develops pressure and vacuum (it pulsates). If you're having constant crankcase vacuum that's making a seal whistle, you have a venting issue.
1) replace your PCV valve
2) make sure your crankcase vent hose isn't clogged
3) find a mechanic who knows his butt from a hole in the ground

Get a new mechainic. He is either pulling your leg or clueless. Even on a new engine the PVC system can not draw enough vacuum to pull past a rear main. If you have ever install a remain you would know that sucking air past it is not easy task and it would require a large amount of vacuum.
Heck just take of the oil cap, does the noise stop? Your engine is vented it will not hold vacuum.

There is no hose other than the one going to the brake booster. The PCV is in the intake plemun, little black cover on top, it even says pcv valve on it.
