    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...

    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...

    [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

    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.

I remember when I first bought the car I was averaging 600-800 kilometers on a tank, even more...
