bag of rocks sound below 2500rpm gone above

[sh0rtlife]

so the bag of rocks sound was gone or atleast very very faint for a long time...the car has always since neer new suffered said sound, toyota at one time while under warrenty said it was the e-brake cable rattling around...and yes the first thing i checked and check often is the exhaust

the sounds gotten ALOT worse over the past week, and can be heard in the car now at pretty much all times below 2500 rpm..above nd al the way to redline the sounds gone...now i wouldnt be terribly worried about it except theres now fine paste shavings in the oil....my guts telling me timeing/vvt...as the sounds comeing from that end...and neer the top..so all things point at the vvt may be failing

the car has been EATING crank position sensors..on swaping the last 2 out they were COVERED in shavings


so im looking for any and all input..car just rolled 190,000 KILOMETERS yes a lil under 120,000 miles..an 07 5dr
