Check top motor mount. It might be loose. If it is, take bolts out, put Red loctite on them, and re-install them. Check other motor mount bolts while your at it.

Chirping can also be caused from a leaking base gasket, but that will not cause a grinding noise. If it has a base gasket leak, you would probably see a lot of oil around bottom of cyl as well.

I didn't want to say anything but chirping can be so hard to diagnose when your running down the road with all the other noises around you.
I love all this on line diagnostics though because you get so much feed back from everyone and it forces you to really think through it.
If your hearing the noise around 2000-2500, take a look at the compensating sprocket. The internal spring can break and cause a hell of a racket. Try rubbing a bar of soap on the edge of your belt and see if that is the cause. Start with the easiest thing first.:zz2cents:
Yep.
Chirp scenario 1:
Exhaust leak; except, this has to be constant. So, chirp-chirp-chirp is the constant.
Belts chirp; more or less in an inconstant way. But some will chirp every cycle spin and remain steady like an exhaust leak or chirp.
Chirp scenario 2:
Belt chirp has to come around every few times, then the chirp occurs. But this may not occur but after so many revolutions and returns. So, some belt chirp are sporadic or come and go.
Cam/roller gall will 'float' or the roller really spins. The way the cam is cut, it rides on the edge of the roller's flat surface, spins and lubes this way. This too is inconsistent searching for 'chirp.'
A. Tighten exhaust clamps.
B. Use bar soap, rub the belt teeth somehow to deaden the noise... If it is belt related.
C. Tear down the engine and inspect, or cut open the oil filter cartridge. This will show evidence inside the pleats. If you have metal debris, the engine is going south.
