[Vwdiesel] 100,000 miles

The thing to remember with sealed roller bearings is the easier it spins,
the worse shape it is in. Sealed bearings when new and or in good shape have
quite a bit of drag from the seals and grease.
I did a KIA L4 engine one idler was 2 inch diameter very dragging seemed
good,
the small 1" diameter idler spin very easy 'like a top' , meaning it was
pretty much trash.
The smaller one spins twice as many times than the bigger one.
I had a 'kit' with all idlers and belt.

btw, I thought all V6 engines used chains (oil-bath) not belts until my
mother in-law asked me about a quote she got from a dealer on her Honda
Accord with a 3.0L v-tec V6.  $1,300 to pull the engine and replace the
t-belt. Ouch!
