VB - VH 253 V8 Diffs Exploding
Holden did the stupid thing of hooking a 6 cylinder diff up to a 253 V8, this causes the stock diffs to explode when put under intense load for long times eg: burnouts, heavy towing. The best solution is to bolt up a 308 diff to the 253 or get a 9" diff for it.

Improperly working rear tail lights. VB - VK (possible VL)
If you find dim, or partially working rear lights, a common problem found is water corroding electrical connections. Thouroughly remove rust from globe sockets and mounts, then the full current can travel through the globe.

Another trick is to drill a small hole under the lens to let the water out.

VB - VK leaking window seals
Stop looking for boot leaks through the boot seals. One of the most common places for the leak to occur is through the window seals (front as well onto the front floor). Usually due to rust under the seal as well. Naturally the window has to be removed and is quite possible that it will crack, especially if there are chips etc. Repair the rust if present,and reseal with a new seal. The genuine VK window seal will fit into all of these and is much superior,also it doesn't have the annoying centre insert! Good Luck.

VB - VK pools of oil appearing next to the carburettors on 253 and 308 engines
Often as a mechanic I see people with complaints about oil in the inlet manifold valley next to the carburettor. The inlet manifolds on blue and black engines warp near the egr crossover and oil leaks past the bolt and forms a pool of oil. The proper way to fix this is to remove and machine the manifold, but a temporary fix is to remove the 2 centre manifold bolts on the right side of the manifold and apply a sealant to the bolts and replace. It's a common problem but can be easily overcome! I hope this can be of use!

VB - VK Substitute Carburetter (Black and Blue Motor)
The most common cause of engine troubles with the 202 motors was the Varajet carbi. It made the engines work to well bellow their potential. A cheap substitue for the varajet is a small Weber (32-36) off of the XE falcons. They cost around $40 dollars (plus adaption plate) and are easily fitted to these motors with only the accelerator cable mount needing to be modified. They not only provide greater horse power but also increase your fuel effeciency. (N/B: With the black motor in the VK the secondary throttle sensor must be disconected and the computer (EST) must be reset.

VC - VK blue and black six cylinder engines erratic idle
A lot of the time erratic idle on blue and black 6 cylinder commodores can be caused by warpage of the inlet and exhaust manifolds. Seeing that the inlet and exhaust manifolds are bolted together but are of different metal compositions, they expand and contract at different rates. After time, these manifolds work loose from the head, which inturn creates a vacuum leak and therefore eratic idle. Usually tightening the manifold bolts along the head rectifies the problem, but in the worst case, the manifolds need to be removed and a new gasket fitted. 9 out of 10 commodores I service have this problem, so it is very common and easily fixed!

VH flasher unit only clicks on left or right turn and flashes quicker
The problem is a faulty earth. Go to the rear lights and check the earth connection of the wiring harness. The problem will be that the earthwire in the harness is not making proper contact with the earth in the plug.

VH (possibly) and VK 3.3L Carby's flooding
If your sitting at the lights and your VH/VK stalls on you and a strong smell of petrol is hanging around, more than likely it is a stuck needle valve in the carby. One solution is to dismantle the carby and rekit it, or another simple and less expensive option is to take the air filter off, and where VARAJET is written, tap on it with a screwdriver. This will move the needle so it sits back in its seat.

Fault- poor ecu harness connection near battery.

VK EFI no start but all appears ok
Fault- airflow meter door jams open.

VK Taillight problems
The VK may see these problems as the indicators, reverse light warning and other dash lights coming on when you press the brake light. This problem (which I have seen on many VK's) is caused by poor design of the vehicle's earthing structure. To solve the problem, first locate the plug in the boot that connects the tail lights to the rest of the vehicle wiring, second, locate the black earth wire (usually melted). Cut the earth wire on both sides of the plug. Strip the wire back and solder the two together, then tape. Don't use quick crimp connectors because you will then suffer the same problem.
