Well there goes my L67 harmonic balancer...

**jlgp2007nc** · 05-05-2013

At least I hope that's what it is. Heard a VERY loud rattling under the hood only at idle and in gear. In the car it seems to go away when in neutral or park. Snatched off the SC belt....still rattling.

Snatched off drive belt...rattling still.

Not seeing metal flakes on the dipstick. Rattling seems loudest on passenger side of engine bay.

Ugh....used parts.

04+ L26

Could be a broken flex plate too, inspect it for cracks.

If you look at the front face of the balancer, it'll usually show cracks and if you pull/push on the belt, you'll see the outter ring move. That's how you can tell it's a balancer.

OK I'll try checking it that way too once I get the car into the shop at work.

time to upgrade.

**BillBoost37** · 05-06-2013

Winner! Easy to fix. Pop the belt.. yank the hb.. put on new..put belt back on.

**jlgp2007nc** · 05-06-2013

Yup easy fix. Swapping over the L26 HB until I get the new one this weekend. Is there much difference between the L67 and L32 HBs?

**Bio248** · 05-06-2013

besides the weights and the extra set of ribs? no.

No they are the same. I know its a little more spendy but the metal one from zzp is well worth the money, just make sure to get the standard sized one not the 5% od one, the 5% od one requires use of a spacer for the oil neck or else you will have one hell of a time putting belts on and you will need to dent your oil filter.
