    VE v6 tuning and longevity / reliability

    Hi guys, I was wondering if anyone has had any experience and feedback regarding tuning a v6 alloytec. I was thinking of getting an OTR, tune, cams and maybe an exhaust (very big maybe on the exhaust). Im not really after power figures as such but just to change up the ride i suppose. I...

    Hi everyone, Gonna change the sump plug crush washer for this next service as I've noticed about a 1-drip-per-day leak on my driveway right under the plug's location where I park the car. Does anyone know the size of the crush washer I need? (Obviously can't measure it because it's still on...

    Weird engine knock

    Hey guys, i have a strange light knocking noise that i can hear when i'm just idling (when the engine is hot / cold). Ive attached a link where i did my best to capture the sound (its easier to hear on full volume). First thing that popped into my head was engine knock but i don't hear it at all...

    Alloytec vacuum leak (cant locate)

    There is a vacuum leak or gushing of air sound coming from the right side of the engine just behind the power steering fluid reservoir and somewhere around the oil filter housing. Ive Checked over all the hoses and haven't been able to find anything. I was thinking it could be the manifold...

    VZ Alloytec Running Rough + Maxing at 4000rpm

    Hi, I have a VZ that has just started running rough when first started and goes away after a short drive. I just changed the fuel filter and same problem. I though I would rev it up in N and P and it will only go to 4000rpm. Thanks in advance

    rtmpgt's super-happy-fun-time LLT mod thread.

    Hi all, So this is a bit of a megathread. It's all to do with the mods i'm making to the LLT that's in my ute. Part 1: Active Exhaust McGuffins. So I'm in the process of developing a few things for my Ute's LLT. I've recently installed HSV Bimodal mufflers, and wanted to actually get them...

    [General] Alloytec Engine Assembly

    Found this great video showing the assembly process of the Alloytec engine. Might help someone. This one is twin turbo, but you get the idea. If only they put a twin turbo 3.6ltr in a Commodore. (Yeah, I know what I'm saying).

    Coil pack engine loom

    Hey guys so I just changed my thermostat and that’s something I never want to do again, I’ve just reassembled everything and tried to turn the engine over and it won’t go, I forgot to plug in a single cable but I can’t exactly work out where it’s meant to go? I can’t see any plugs near or around it

    Codes P0008, P0009, P0016, P0017, P0018 & P0019

    Found this juicy nugget of info. So timing chains may not always be why timing is incorrect. Movement of the tone wheel can be a problem. Of course, it means the engine is pretty much fkd. Have to replace the crank...

    PCV or MAP sensor issues not sure what’s next to try fix.

    Shortly after doing a service on my 06 alloytec the check powertrain warning came up and so I used a cheapo OBD2 dongle to find the fault and got a reading of P0105: Manifold Absolute Pressure/ Barometric Pressure Circuit. Most people seem to say that this usually indicates a vacuum leak and...

    Don’t always assume timing chain!

    Thought I’d post a quick note to describe my recent engine issues- vz alloytec 3.6 with about 207,000k Was way down on power, running rough and check powertrain was coming on all the time especially if I tried to apply any force or go up a hill too quick. Fuel economy had gone off the chart...

    Motor swap and conversion

    To put an 05 VZ alloytec and 6sp manual box into an Auto 06 VE Omega, would that be a stuff about or what? How would I go about doing that with the possibility the ecu and computer won’t plug in. Worked on about every other car bar a Holden.

    VZ Calais: Exorbitant fuel consumption

    Hi all, I've recently noticed that the fuel consumption in my 2004 VZ Calais has been pathetic. I'm averaging 300-400 kilometers per tank, and according to the l/100km it works out to be 15-17 litres. I remember when I first bought the car I was averaging 600-800 kilometers on a tank, even more...
