How would that work? Do pieces of iron fall off of the crankshaft? Do some of the connecting rods loose flakes of steel? The crankshaft does not damage the harmonic balancer; on the contrary a balancer gone bad CAN snap a crankshaft. Rarely gets that far on a Corvette, but the 6.2L GM diesel in the pickup trucks suffered their share of broken cranks when the harmonic balancer stopped doing its job.

I've replaced a dozen of the LS3 hb's.Quite a few of the LS3's were made compared too the LS2's.The p/n on the balancer is the same for both.

The elastomer rubber between the inner and outer hub delaminate and spin on the hb causing it to go out of balance.When that happens it causes hubs to move in or out also

I had mine 12 years and 85k miles, drove it like I stole it and the engine still purred! Mine did consume some oil but nothing obscene.

1) Upgrade the harmonic balancer - OEM one is garbage
2) Get an oil catch can due to V8 and DI - NVM apparently not DI

Really only things that come to mind otherwise mind has been rock solid *knocks on wood*

These aren’t DI engines.

Thanks didn't know they were port injected. Im surprised with the recommended use of an oil catch as I was under the impression port usually mitigates the need for an oil catch.

Yeah, the guy in the video is an idiot. He is not talking about harmonic balancers failing, he claims the engine is losing "internal balance". There is no way for that to happen unless there is significant damage to something in the crank/rods/pistons/flywheel. He is an idiot.

Fairly sure you lose the factory engine balance if the damper is changed without replacing the weights in same location as the factory installed.

They're recommended sbecause a sicker buys a new vette every minute.

In all seriousness, they get recommended because when people buy a vette, camaro, srt product, or pretty much anything similar where they get recommended a lot, it's because people want to take extra special care of the car because it's their baby. How many silverado work trucks do you see with catch cans? Almost none, because they're not gonna spend however much on a catch can so they can marvel at all the quarter ounces of oil they accumulate.

My LS2 has never left a drop off oil on the floor. 2007 with 75k miles. Power Steering pump leaks though...

h8snow

Nailed it. Funny.

ssg10587

Haha Good to know. I spent like $30 on something with some vacuum lines. I get like an oz maybe every thousand miles, so makes sense they're overblown.

demon340

mine has about 65K,, replaced the balancer with a powerbond and arp bolt, also pinned it. High preasure P/S hose is prone to leak, i replaced mine. Great running engine

I just watched that video and I can't believe he made a statement like that without further explanation. I agree, he has zero credibility.
