Alloytec engine clattering on start-up

**twb1979** · 01-09-2007, 04:09 AM

I know their was a thread on here before about a member who was experiencing that engine clattering noice on cold engine starts and he was going thru the process with a Holden dealership.

Just want to know what the outcome of this was as mine Adventura does it when it's stone cold. Only does it for a couple of seconds but it's annoying and embarrasing and most of all it doesn't sound healthy. It sort of reminds me of those Ford barra engines starting up...

Anyone else had a similar issue with their motor?

My old SV6 with 55,000kms on the clock was whipser quiet from day one.

hey benzor, howd your motor go? - can you do a "my ride" with pics of your engine before and after and all your other mods.
im keen to check it out

**benzor** · 01-09-2007, 05:53 PM

Its ****ed.

Holden cant bolt a gearbox back in

After my nice fresh rebuild, the gearbox and the tailshaft let go leaving me with some $8000 worth of damage.. and injuring me.

**impulsesv6** · 01-09-2007, 06:20 PM

any reason why? - too much torque?

**benzor** · 02-09-2007, 01:09 AM

Holden dealership negligence.

My car was returned to stock a long time ago

when i stopped chasing power out of an unreliable v6 that kept breaking
heres something for eevryone
you want power
buy a v8

you wan to mod it?
get a v8

Alloytecs are **** and ownt make it past 70,000k's with any decent power.

**crewzincool** · 03-09-2007, 04:15 PM

The latter,

Holden's paying for it.

**crazywog** · 04-09-2007, 04:11 AM

go my car being an ecotek

**vy-346** · 04-09-2007, 04:55 PM

So nothing has really been the cars fault has it??? or has it... i'm not really clear on it but wasnt it started by you losing an engine due to bad fuel and then another one to fuel and now the taily has come adrift after the 2nd rebuild due to holden negligence?

First rebuild holden negligence
Second one i THOUGHT was bad fuel, turned out it was a spun bearing
Now this is ****ed, going for number 3.

The alloytecs are a piece of ****

**f1tzy** · 04-09-2007, 11:17 PM

I don't like the alloytecs either. The ford 6 is much better, although their 8 is piss poor.

**CacTuar** · 08-09-2007, 02:27 AM

My ute is at 80,000 ks and I've never had a problem. Must just be lucky..

so is this something the dealers should do if you ask them, or is it for certain circumstances?

**Torquative** · 03-10-2007, 09:03 PM

fark ... we find this out now that my car has just clocked over 100 000kays and makes the warranty void

I'm nearly in the same boat...Your dealer mech mention if this is a common problem Tom? I can't get mine to make the noise two days in a row so I assumed it was something minor like heat shields expanding or something.

You would think it would be recall worthy if it's something as serious as oil feed issues to the heads.

More info would be very appreciated.

**=SKB=** · 04-10-2007, 10:11 AM

Also just how loud a noise are we talking?

Mine is not that loud, almost can't hear it in the car. Does it get worse over time or is something you really notice from new?

**tom johnson** · 13-10-2007, 09:45 AM

my motor has been rattling on start up since new,it sounds like the old motors when started after doing an oil change,my dealer is now going to fix the problem ,holden tech dept says some early motors did not have oil check valves in the heads and the oil drains out when it shouldnt,they have to pull the heads off to do this,will keep you informed if this is fixed.

**tom johnson** · 13-10-2007, 09:47 AM

it would be done under warranty, be persistant
