GM 12587093 Purge Solenoid Valve ~$120
Alternator notes about top brand differences; Bosch and Holden OEM (ie Mitsubishi Electric) is that Bosch has a ratchet pulley – ie if you rev the car up and change gears at 6000rpm, the alternator does not suddenly go from 6000rpm to 2000rpm, it continues to rotate and slow down on its own account until it catches up with the belt at 2000rpm in terms of how that results in longevity I do not know, but I can see why a ratchet pulley style would be ideal for anyone who drives hard regularly, especially in the v6 where you the alloytec just loves.. to climb revs.
Removal: We have used the cheap 3-jaw puller will remove the balancer fine, screw holes line up, and correct screw sizes. We also have tried to use the MACE Engineering harmonic balancer puller, but it does fit the twin pulley harmonic balancers we have on the Adventra LY7s so don’t waste your time. Install: To press back on, do not apply heat or use excessive impact force instead get an m14x1.5 bolt that’s fairly long. Wind bolt in, then use a spanner to wind nut in, once firmly on then torque up the crankshaft balancer bolt as per the below item.

GM 12588222 Crankshaft Balancer (aka Harmonic Balancer) but do not stock anymore alternative is now POWERBOND HB1506N OEM Spec Aftermarket Harmonic Balancer (Twin Pulley) to suite Adventra & Cross6 Crewman Alloytecs. ~$400 + postage.
GM 11569873 (or alternative available Crankshaft Balancer Bolt GM 11549124) which is needed if you remove the existing bolt, are torque to yield bolt, so they should only be used once. If you must reuse, apply thread lock as a hack, but if you want to do the job properly reuse old bolt, and purchase another bolt, once it arrives swap them over, and torque to step 1. 100Nm and then step 2. additional 120 degrees.

Safari SS96 0HF Snorkel – Fitment (v6 or VZ+ V8 only) as proposed positions for cut in will be above the airbox position as discussed with Safari. Snorkel project has been pulled, we are now looking to relocate intake under bonnet but protected from bow/pressure. Expected retaining water level 700mm crossing safe.
We ended up using a 65 series Hilux passenger side snorkel and fabricated an install, been running for 12 month and it has done the job great. Approx. $150 in materials all up plus some time. Start with part 1 here and see if it’s something you want to do.. https://www.youtube.com/watch?v=gNNLF68lzpI
LY7 Manifold Notes
Spark Plugs: 16-20Nm
Coil Pack anchor: 7-11Nm
Upper Intake Manifold Bolts: 23Nm
2006 GM 12609418 (Blue) 06 does work with 05, unsure what’s exactly different other than color. Approx $500 for a set of 6 if genuine.
2005 GM 12571159 (Black) 05 does work with 06, unsure what’s exactly different other than color. Approx $450 for a set of 6 if genuine.
LY7 Oil Pressure Sensor/Switch/Pickup
2005 – 2006+ GM 12621649 aftermarket between $20-$40 (Genuine should be $70+)
GM 12566837 comes up as the correct part for the oil pickup seal/o-ring but now displays as GM 12691257 (revised) part which has superseded the previous part number and is the official substitute for GM 12566837 & 12615569 seals/o-rings. Expect to pay $20-30
LY7 Timing Chains
GM 92509866 is for the chains up to vehicles with VIN starting with 6L859056 which is most V6 Adventra’s although if you are past this VIN range you will need GM 92511366 as this is the one used generally post 2006 Alloytecs in late VZ’s VE commodore ranges. Expect to pay around $800 for genuine timing chain kits without gears most of the time you will not need gears if doing timing chain due to codes P0008, P0009 P0016, P0017, P0018 & P0019, there are some aftermarket ones pricing between $450-600 as well. Timing chains can be done while the engine is in the vehicle and is a days job if you have an idea of what you are doing. Workshops will generally charge you 5-7 hours in labor for timing chains ontop of costs for new seals, gaskets and chain kit.

VZ V6 5L40E and V8 4L60 Passive Transmission Cooler (100% required for V8, it will save your transmission… V6 is optional however highly advise it if off road use) – PWR 6690 (also listed as PWO6690) around $200-250 delivered.
Spare Hose Set Gates Radiator + Heater Hose Kit V6 VZ This kit is the one we carry, includes full replacement so you’re never short off road during a failure – https://www.ebay.com.au/itm/143163137060 we carry a full set always in the Adventra if we use one we snap a photo and replace it with one from supercheap. Its easier to buy this kit then you know you have all the right part numbers and items.
Bearings – Purchase Genuine NSK Front Wheel Bearing Assembly Here
Front left and right are the same item, they are not directional and we have tried the cheap $100 version and premium NSK made in Japan ~$300 version (per side). For off road you must get the NSK version if you don’t you’ll be changing them again in 1-2years times or less than a year if going off road. Poor man buys twice, once replaced with NSK’s we’ve not yet needed to change them again.
Purchase Genuine NSK Rear Wheel Bearings Here can be a lengthy job if never done before, but achievable with a cheap bearing kit as the hardest part of the job is to get the existing bearing out. Remove hex 8mm bolts holding the rear CV, once removed unbolt the collar nut and remove the locking plate, you then can tap the rear outer wheel driveshaft outward, once removed remove the retaining clip on the outside of the hub, and use a bearing kit from the inside to push the existing bearing race out. Once everything is out clean and install the replacement bearing in the reverse order using the old bearing outer race on top of the new bearing outer race to tap gently back in until seated to reinstall the retaining clip. Press/tap in the rear outer wheel driveshaft into the inside of the bearing been careful to do it evenly until seated and reverse the order of the collar bolt removal process to reinstall everything.
The Rear Brake/Parker Globe Should be OE spec Philips P21/5W (Twin filament, clear globe), it seems the Phillips brand lasts longer than the Narva brand ones bulbs, expect to pay around $20 for a pair. They are not the same as commodore globes.
HVAC – Heating, ventilation, and air conditioning system
Are you having issues under acceleration that the air vent changes from front to windscreen and then back again? You may need to replace an actuator they are easy to do most common one is GM 92140681 ~ $80 new. There are 3 but it’s very common that the driver-side one is the one to go accessible from the kick panel behind the center console.
Engine Compression Alloytec LY7 Troubleshooting
- The lowest reading should not be less than 70 percent of the highest reading.
- No cylinder reading should be less than 965 kPa (140 psi).
- If a cylinder has low compression, inject approximately 15 ml (1 tablespoon) of engine oil into the combustion chamber through the spark plug hole. Measure the compression again and record the reading.
Normal — Compression builds up quickly and evenly to the specified compression for each cylinder.
Piston Rings Leaking — Compression is low on the first stroke. Compression builds up with the following strokes but does not reach the normal compression amount. Compression improves considerably when you add oil.
Valves Leaking — Compression is low on the first stroke. Compression usually does not build up on the following strokes. Compression does not improve much when you add oil.
- If 2 adjacent cylinders have lower than normal compression, and injecting oil into the cylinders does not increase the compression, the cause may be a head gasket leaking between the cylinders.
- Cylinder leakage that exceeds 25 percent is considered above acceptable and may require component service. In the above acceptable leakage situations, inspect for the following conditions:
Air leakage sounds at the throttle body or air inlet hose may indicate a worn or burnt intake valve or a broken valve spring.
Air leakage sounds at the exhaust extension pipe may indicate a worn or burnt exhaust valve or a broken valve spring.
Air leakage sounds from the crankcase, oil level indicator tube, or oil fill tube may indicate worn piston rings, a damaged piston, a worn or scored cylinder bore, a damaged cylinder block, or a damaged cylinder head.
Air bubbles in the cooling system may indicate a damaged cylinder head or a damaged cylinder head gasket.
Perform the leakage test on the remaining cylinders and record the values.
