Alloytec and You

[mr_s]

Hi all.

So, recently I bought a 07 VE Lumina. It's the first commodore I have owned, and love it.

However, during a brief visit to my mechanic (for brother's car), he took one look at mine and said the Alloytec engines suffer from stretched timing chains.

Browsing through the forums, I confirmed this is the case for 2006 models; which I guess were the first Alloytec batch.

Now, how do I determine if my VE has the new revised timing chain, or is one of the first few batches?

More info:
87 000 km on speedo
Manufactured in 08/07
Engine Number: LEO 072040265

Searched Google for engine number to no avail.

Cheers,
S

Im prety sure that was with the Vz alloytech but i could be wrong
Ve alloytech was improved as far as i know

One, two, three, four and five say otherwise...

Definitely an issue with 06 VEs. Perhaps give customer no-assistance a buzz with your vin number. May be able to help.

Gday mate.

I also have a Lumina. Love it alot.

Don't like the front grille though.

I've got a MY06 VE with the Alloytec - just hit 101,000km and haven't had an issue... yet.

And ask if these cars have had timing chain problems, or what batch the car was?

Glad to hear it. Lot of people on here have had 06 timing chain problems.

Don't look at "my ride", I have made a typo (late at night, etc etc)

So, no members, other than Wongy and myself drive an 07 Lumina here?

mr_s, looks like you're safe. The service bulletin says;


"This condition may affect the 7.7 mm pitch timing
chain, installed in engines after the following engine
number: H053340001."

and

"Improved timing chains were introduced from the
following breakpoint:

Engine Number H071380576
Eng Built Date: 18/05/07"

and "Typical expectation is that ECM detectable chain elongation
would occur in early engine life (i.e. 10,000 to 20,000 km)."

That's quite comforting to hear, my 06/07 SV6 hasn't had any timing chain issues and I hope it stays that way.

Mine has 113,000km and no synptoms so far..

Z3RO a member on here had his chain strech, causing valves to hit the pistons and stuff his engine.
