I read that wrong again:
Loss of power across the band
Rough idle/engine shake (if one or more cylinders are extremely low)
Oil breakdown (fuel in oil, blow-by), check under valve covers as well.
Lower than normal vacuum signal
Exhaust emitting blue, grayish smoke
Look for:
Ring wear
Cylinder taper
Weak/broken valve spring(s)
Head gasket leak
Valve sealing (seat wear, carbon build-up on back of valve)
Valve timing (cam selection)
Loose spark plug
