VZ tapping noise = New Engine

[oscillator_1]

Hi,

A friend of mine has a noticable ticking noise coming from the motor of his VZ which was loud.

He was very concernced so he took it to a local Holden dealer which 3 mechanics listened to the noise.

The outcome was that it was not normal / within tolerance.

Holden advised the dealer to replace the lifters.

The dealer replaced the lifters. Noise went away, but when engine warmed up the noise came back again.

Holdens advised them to do an oil pressure check.

The dealer did so and the outcome was a new motor.

The original motor had only done 5,000km.

The dealer advised him it would be a brand new crate motor.

He questioned them about it being brand new and they assured me it would due to the low km my original motor had done.

The original engine number was VF05033XXXX

The new engine number is VF04294XXXX

He found out that the fist two numbers after VF is the year and the next three numbers after that is the day it was made.

His original motor was 2005 built on the 33rd day

The replacement motor is 2004 built on 294th day

He is a little pissed off why the replacement motor is a 2004, although late 2004. 71 days short of being 2005.

Anyway he is running in the motor again as per the holden book.

See how this one goes.

He does not know what the cause was or what they found. Should he follow it up ??

Would you accept a 2004 block motor if your original one was a 2005 ???

My enging is qiuet with no noise, I hope it stays this way.

CHEERS

I'm starting to wonder if the VZ's are starting to have issues now See this thread http://www.ls1.com.au/forum/showthread.php?t=47938 Looks like some of us have some issues. May be just a ticking sound but may be more serious. Time will tell. If any tuners or technicians can shed some more light on this issue it would be great. I thought Holden revised these engines from VYII Up.

i had seen a blue vz ss in a holden car workshop minus an engine , bout 3 mths after they were released , but no matter what happens i guess since it is a mass produced item , lemons will still make their way to the dealers , hope the new eng for the vz/ ve will have better results.

if it makes you feel any better fords arnt havin a great run either so i suppose its unlucky if you happen to get a replacement now holden has been dealin with it for so long

There's always a percentage of cars where they hae a problem. BMW has them, Ford has them, Ferrari has them etc. etc. etc.

Even with the most carefully hand-assembled engine there can always be flaws in materials, cracks, contamination in forging and so on. In mass-production the same happens.

After the revision in 2002 all LS1s are the same - (better) LS6 block and intake, LS1 heads. No real difference in a late 2004 or an early 2005 build. The main thing is, a changed engine that's documented in the service records - that can actually be a plus because a complete new crate motor means a niggling worry with secondhand LS1s is averted.

Would you accept a 2001 engine block when your car is a 2003? Well .. my "replacement" engine did show up at 80,000km so I should be grateful shouldn't I?

[muayyadf1]

No problem with that,I have a 04 built VZ SS with 25000 Km's on it,no problems and it's getting more powerful;)

build date doesn't matter if it's well assembled:cool:

Except when it comes time to sell. Ofcourse *everybody* wants an older engine in a car don't they? [ actually I'd like an '70 LS7 454 in my Commodore? ]

Rod.

[muayyadf1]

at least they won't be crying out "my engine has a piston slap,help me!"


:lol:

[wrexed03]

My car has engine tick instead. :bash:

[muayyadf1]

My car has engine tick instead.


Don't worry about it,it's either injector noise or a slight exhaust leak noise :D


may be both ;)


just ignore it :rolleyes:

[VTSSDUDE]

I don't think there would be much difference between a 2004 Gen III and a 2005 Gen III. As said after 2002 they were all revised. But as I have read someone had a VX Series II after their engine swap they found out that the new engine was dated 2000 so then you would have the right not to be to happy.

Cheers,
Jim :cool:

My "tick" seems a bit less lately. Don't know what it is. Suppose I'll just wait and see if it get worse. It has a 5 year full factory warranty anyway. I suppose that'll be void when I do the cam though!

[muayyadf1]

The build date noted above(VF04294XXXX) is for VZ model (the latest LS1 version ) which has ETC and new designed pistons.

I think the date is after the VZ model unleashed :cool: .

Lifters are same part number for vt to vz although the lifter guides are different... Maybe this could have something to do with it?

[oscillator_1]

What The F**K :mad:

After 260 km my mates ticking noise has re-occered with the brand new engine.

What the hell is going on with these motors ???

Condition

Some customers may comment on an engine tick noise. The distinguishing characteristic of this condition is that it likely will have been present since new, and is typically noticed within the first 161-322 km (100-200 mi). The noise may often be diagnosed as a collapsed lifter. Additionally, the noise may be present at cold start and appear to diminish and then return as the engine warms to operating temperature. This noise is different from other noises that may begin to occur at 3219-4828 km (2000-3000 mi).

Cause

The O-ring seal between the oil pump screen and the oil pump may be cut, causing aeration of the oil.

Correction

Inspect the O-ring seal and replace as necessary. Use the applicable part number listed below. Refer to the Engine Mechanical sub-section of the appropriate Service Manual.

What should he do from here ???

Surely Holdens would have told the dealer to check the above :eek:

Any comments ???

Every LS1 has a ticking noise, but not loud.

If it's loud enough that you can hear it inside your car,there is a problem :rolleyes: .


Mine has it when the engine is very cold


but it goes complelty away when the engine reaches the normal operation temp.

Update on this the boys at the dealer had another look. Looks like a new set of lifters are going to be installed since the noise is coming from the valvetrain area. They had another one in there recently exhibiting the same issue the lifters were replaced and the customer was happy with the end result. Apparently its a decent job the heads will have to come off to get to the lifters. Not like the early V8's. Just stating what i was told not sure if this is the case.

Just a question. If the engine is replaced, does it come with a new compliance plate with new engine number? I know If went to buy a second hand car and the engine number didnt match the tags, I wouldnt touch it. Id be thinking this car has had problems and may have more to come.

Mine didn't. I have the original document from the dealer with the new engine details and VicRoads have the new number so legally it's OK .. just doesn't *look* good. But to the "unsuspecting" I can say it have a "new" engine fitted at 80,000km! :D

umm...the engine number isnt on the compliance plate ...its on the engine only...so theres nothing to *look* bad at all.

Holden should tell the authorities...just remember that you tell your insurance company and finance if its on finance of course

[jaskel]

mine has the same ticking noise, when I got it serviced the dealership said they couldnt fault anything...IM LIKE WTF!!!!!

Dunno what to do....

[wrexed03]

All i can suggest is try another dealership get chummy with the techs and hopefully it works out. But definetly keep pushing them.

Regards

[jaskel]

oh i aint stopping there....ill fight em all the way...im going to take it to the dealership where i used to work...i know a few of the techs there.

[spanks]

Has your mate asked what type of oil the dealership is using.Seems a bit odd that 2 engines in the one car in such a short space of time would have the same type of noise....

[wrexed03]

Just an update on this the lifters were replaced in the vehicle which ment a removal of the heads etc etc etc. Got the vehicle back just now and if anything its worse now than what it was before. I will give it a couple of days of some decent driving to make sure the lifters are primed up properly and see if it quietens down some what. If it doesnt improve in the next couple of days i need to inform the dealer to get someone out from Holdens to have a look at the thing. What more can i say im not happy.

[jaskel]

bummer....please keep us posted as i am about to go thru the same thing here...

I hope it will improve for you. If it doesn't, make sure you hammer Holden about it and don't take any sh%t !

:shock: another sad ls1 story,my lumina has done just under 45000km so i'm just hanging on for these problems to be erased before i get back into a v8 so seem i'll be waiting for the ve to roll in.

[Y2kGoofball]

we're starting to observe the Alloytec 190 as well

So far mums had 2 SV6es as a company car, this is the 3rd. The first one was replaced at 15 000K's, the second one at 20 000k;s and this one will be at 40 000k's (theyve just realised it costs too much to change ever 10 to 20 000 k's)

Anyway the last 2 had no problems whatsoever, ran like dreams, no rattles, whines or noises, but this current one seems to run a bit noisey and has a slight whine. The Adventra has roughly the same ks on it (14000 ish on each car) and it doesnt sound as loud or have this slight whine.

being a company car we're more then happy to let it sit and see what happens but its a bit of a concern because weve got 2 of the alloytec 190s under the carport and the engines sound different. If anything we thought the Addy would be the one with a whine or a noise because its the one carrying more weight.

so we'll see how it goes, but if the Adventra starts it we'll be onto it :bash:

[wrexed03]

Just another update took the car out tonight with the family for a decent run seems to be much better now. Definetly an improvement looks like the problem could be cosidered as resolved will keep an eye on it and see how we go if i have any further updates i will post.
