LS3: Rattling sound when stone cold

[macca_779]

Changing a cam does not automatically mean you’re going to render lifters unserviceable. The fact that many engine builders have no idea when assembling these engines is a far larger factor. Valve spring selection and setup as well as pushrod selection can often lead to premature lifter wear and noisy valvetrains.

I have never heard of anyone replacing standard lifters on a standard engine every 100,000kms

or ever seen it as a scheduled maintenance in a service book on any vehicle.

There's a GM service note about this some where, not a recall but a service advise thingy. Only 6L gen IV engines

Found it, this applies to vf but also AFM ves

Thanks for that link Blackve.

Just a couple more tidbits of info:
That other LS3 driver I mentioned who lost his engine listened to my recording, and said that his sounded like that all the time - even when warm. So, in fairness, it's not fair to put ALL the blame on the engine for blowing up, because the problem wasn't addressed immediately.

Had another chat with my repairer. They said they agree with that Oztrack article - re replacing them every 100,000. They also agreed that it doesn't matter what lifter you use - they all fail, however they've found that the LS7 lifters seem to be the most reliable.

Don't agree with this, the 6L & 6.2L engines, very few failures on stock engines.

Sounds like some of the VF's must have had some bad or faulty lifters which failed early fitted in them.

Pity that if Holden was made aware they did not do a recall & replace the bad parts.

You urgently need to do a cam swap on your new ute Mick!

Thinking of selling it before I do Ed

Only recall on the VF to do with valve train problem in the LS3 were a batch of faulty rockers that affected some builds in My17.

No Mick, don't sell it, you would regret it.

Again - in the HC industry, I completely disagree with you - a very high percentage of us have had lifter failures. I've just asked yet another mechanic - he's just a plain simple mechanic who does a lot of limos - he strongly agees that lifter failures are common with the 6L engines.
Again - the advice to change lifters seems to make overwhelming sense to me.

My Daughter said that too!

The member with the 500,000km LS1 from memory is in the hire car business & I think he is in Melbourne
but I could be mistaken on that?
He had a thread about his car but I can't locate it or remember his username at the moment.

If anyone else can link his thread it will be greatly appreciated.

Helps if I go to page 2 and find that it is already found!

Lifter failures in the gen 4 have been around for years some low kms(rare)and now with best getting up around the 200k mark more common. Holden don't care. Seems no common link few well serviced and still had issue. Slot complaining about last ls3s being noisy but my Jan 16 build is quite as a mouse only 6500km though. Uncles ls1 wh had 310000kms sounds like a tractor but still going strong(little oil burn)

No such thing as a lifter failure at 200K at that mileage there fukked & due to be changed anyhow!
