    4L60E VX V6 issue

    The symptoms you describe don't sound like a slipping transmission. If the trans was slipping your revs would go up with a lack of acceleration. Your revs wouldn't match your speed if you understand what I'm saying. You wouldn't have problems getting the engine to redline. Sounds more like...

    Think i fkd up

    You didn't mention the cost of a head gasket so thought I'd mention, up to you but I queried my engine machinist in regards to re-torquing head gaskets. He didn't recommend it. It might be perfectly fine but for the cost of a stock head gasket, personally I wouldn't risk it.

    Lifespan of standard parts...

    Got 340,000 out of my DFI module. Slightly less on one coil pack. Others were fine but replaced all 3. Never replaced a TPS, IAC, IAT, nothing, in 340,000km. But the never thrashed trans ruptured its' guts around 160k, tailshaft bearings at about 240k. Oh and it dropped a valve (busted collet)...

    What is the best online aftermarket part shop for my V6 Ecotec N/A

    I've also had good dealings with Intense. Picked up a few bits and pieces from them back when the Aussie dollar was around parity so got some nice deals. Mace are a site sponsor and I have a bit of their gear too. Always found them to be helpful with parts and enquiries in the past and I'll go...

    Vt not starting after rocker install (backfires)

    No argument with your post as far as loading up the assembly, what I'm struggling with is why the pushrods wouldn't be the right size. I'm running a decked block and shaved heads to the point I could just get the LIM bolts to align and running the same lifters and pushrods in an engine I've not...

    Vt not starting after rocker install (backfires)

    I have to ask a question. It may be obvious but it's a mistake i made years ago with one of my first engine builds. I have done this exact job you're doing with the 1.98 rocker arms and Comp Cams pushrods with no issue myself. My question is, when you torqued the rocker arms did you crank the...

    250cc injectors in a VX commodore

    I'm assuming V6. Stock pressure at the fuel rail is 3.5 bar/50psi. If that's what your injectors are rated at, you're fine but if not, well then yes. Your fuel rail needs to be at the pressure recommended by the injector manufacturer. Refer to your documentation. If the injector flow rate is...

    supercharged Vt v6 wont start

    Hey Delcowizzid, are you able to elaborate on your post above? It's just to eliminate possible issues as I just dropped an 'L67' in to my car today and I'm going to be using the loom that came with the top end, mainly because of the fact it has Calais/Statesman plugs on the transmission...

    VT Commodore strange noise

    Sorry if this seems obvious but I had a chronic steering fluid leak which turned out to be one of the steel cooler lines rubbed right through the metal. Being that I knew I had a pre-existing steering pump leak when it started to get bad I just assumed it was that getting worse. Point being...

    Installing VY Ecotec in place of blown L67 VX calais.

    Fuel pressure is regulated by the fuel pressure regulator on the fuel rail so the higher capacity pump is irrelevant. I ran an L67 pump on an L36 for years without issue. You are correct that they run different fuel pressure. If you get a N/A tune for the L36 it'll be set up for the factory L36...

    vt v6 head gasket on wrong side?

    Yes, you can fit them to either side. They're the same.

    vt cruise control problem

    Had a similar problem with mine (VT) some time ago. Replaced indicator/cruise stalk, problem solved. Can't guarantee that's the problem with yours but it's the same symptoms as mine. I have a few 'spares' these days. New aftermarket are like $20.00 delivered on Ebay.

    Vx Calais super6

    Fronts will bolt on fine. Rears will go in place fine too but you'll have a gap between the seat backs and C pillar area because the Statesman is longer in that section and has extra trim to cover the gap. You would need to do some modification there. Also the Stato rear backs have holes where...

    VT V6 Starts every few hours then no spark

    *Fixed* I received the new crank angle sensor yesterday and went about fitting it this afternoon. Started first go. Now I get to diagnose the engine noise it started making just after I got it home. I think the 'new' motor might be going in just in time. Thanks again to everyone who assisted.

    VT V6 Starts every few hours then no spark

    Just an update. Many thanks to @chrisp for the diagnostic article. Seems like it's the crank angle sensor. I ran through the tests systematically when I had time. Couldn't do them all in the same session unfortunately. Nonetheless prior to doing the 3x CKP test as outlined in the link...

    VT V6 Starts every few hours then no spark

    Thanks. I'll have a read at my first opportunity. Sometimes the way that seems the longest and most difficult at first glance can workout to be quicker and simpler in the long run than attempting short cuts.

    VT V6 Starts every few hours then no spark

    Cheers Lout. I'm gonna follow yours and delcowizzid's advice. Again, could be a while re-posting Other things also need my attention. Absolutely appreciate your assistance. FYI, my family owned mechanical repair shops throughout my formative years. With 4 full time mechanics and two...

    VT V6 Starts every few hours then no spark

    Cheers mate. Valuable information. You're on pcmhacking hey? Any ideas? Even if it's just where you might suggest I fault trace based on the information I've provided. Just bear in mind, I'm no electronics wizz myself. With this stuff it's a 'learn as issues arise' thing for me.

    VT V6 Starts every few hours then no spark

    OK, well yesterday (Saturday) I couldn't start it at all. I had to get stuff from my car on several occasions which meant unlocking it. On a couple of occasions I forgot to lock it which all in all meant that it didn't sit locked for several hours at a time and I had no luck starting it and it...

    I'll do this after I determine I have a signal at at the DFI plug. Can't hurt.

    VT V6 Starts every few hours then no spark

    Cheers Lout. I value your input. This one has me stuffed. Unfortunately having swapped the BCM and ECU I no longer have any fault codes. If only I could start it & drive it until the CEL lit up. :( Bridging pins 5 & 6 has not worked on my car ever AFAIK. That was the reason I was going to...

    Flickering headlights/ dash lights

    The things you have done, particularly checking the earths, is exactly where I'd start looking too. Having said that, have you checked the light switch itself? This is not an issue I've encountered so I'm just throwing it out there but it seems a logical area to check. The switch could be...

    VT V6 Starts every few hours then no spark

    Mixed feelings about posting this as my expectation of anyone having had the same issue is extremely low. I have found some slightly similar issues but none identical in hours of scouring forums. VT V6. Has been throwing a CEL. Has been occasionally missing but often runs perfectly fine...

    Coolant problems?

    I know this is the theory but how does this actually work? The cap has a spring to release 'expanded' coolant (I know.. it doesn't actually expand until it reaches atmospheric pressure but it 'wants' to) at a set pressure but as soon as the pressure drops it closes again and it happens pretty...

    Got a few problems with my 1998 vt commodore

    Try bleeding the air from the cooling system (3 bleeders on the L67?) and re-topping your coolant. My radiator just blew a hole and it also fluctuated temps pretty wildly while I limped home. If it drops to cold you may not have a thermostat installed or it may not be functioning properly. I...

    Does not want to start cold

    I had a similar issue two years ago. Car had done about 300,000 at the time. The advice I got right on this forum solved my problem. Turned out to be the fuel pressure regulator. Overnight the fuel would drain back to the tank and combine that with low temperatures and contracting fuel and you...

    VT VX DASH CLUSTER

    Cheers. Good to know. Ring around but as I said, my guy used to charge $10. It literally takes 5 minutes. I wouldn't be too happy to pay more than $20 for the 5 minutes work they'll do plugging in the tech2, sitting in your drivers seat and pressing a few buttons.

    VX L67 Harmonic Pulley Removal

    Also if you have a cheapie puller the centre bolt may not be long enough to reach deep enough to the crank. I use a round metal bar about 60mm long (without digging it out and measuring it right now) and a diameter a little smaller than the hole in the crankshaft. Some people will put a socket...

    VT VX DASH CLUSTER

    Agree with Dayvo. Don't forget to disconnect the battery beforehand or it'll also throw an airbag fault and if you have access to the donor vehicle you can tell by the module under the centre console whether it's a two or four airbag module. Equally the seats will have the SRS loom running to...

    VX climate control vacuum leak

    Well I've worked on numerous VT's on since 2000 and I've never seen a vacuum reservoir inside the guard nor is there any mention of one in the GMH Service manual. Below is a pic of the vacuum schematics for ECC and a photo and description of the location of the vacuum reservoir straight out of...

    VX climate control vacuum leak

    The reservoir in the LHF inner guard is your coolant overflow reservoir and has SFA to do with your climate control.

    fuel consumption problem

    It's a long time since I researched this but as I recall, to test O2 sensors you would need to heat them and use an ohm meter to check the voltage. Google it to be sure. Agree with Towcar. Serviceable item. Get a pair off Ebay.

    VT BERLINA - help needed

    Starter motor solenoids don't like heat when they're dying. Mine used to do this. Wait for it to cool, away you go. That wouldn't cause it to 'just shut down' of course but it could also have a dying Crank Angle Sensor which absolutely could. I'd do two things. Pour water over the starter when...

    VX climate control vacuum leak

    Probably a vacuum solenoid. You have 3 options to direct the air, screen, face, feet. You know it goes to the screen so likely the solenoid that directs air to face or feet. When I upgraded to climate control the HVAC box obviously had one dodgy solenoid. If I set air direction to feet it stays...

    engine stalls while driving!!?!?

    Checking the error codes is always wise. It has the symptoms of a CAS issue but you say that's been done. The next most common reason for stalling while driving is fuel pump. Your oil light is coming on under braking because you don't have enough oil in it. They don't need to be more than a...

    vt aircon not cold??

    I recently installed brand new compressor, tx valve, condensor, evaporator, receiver drier, heater tap, everything bar the hoses basically. A/C guy gassed it with R134A as per original. Checked for leaks. None. All pressures both high and low side spot on. Still nowhere near as good as it...

    after market electric windows switch

    OMG! Are you a politician or something? What an awful lot of effort having to hold that button up for 4 or 5 seconds. Bit too physical for ya? ;) OK, seriously, yes you could do it. How? Dunno, I'm not particularly well versed in electronic circuitry. The auto window winders on Ebay have...

    Changing vt fuel pump

    You can swap the actual pump from one assembly to the other. That is your only option with the broken pipe. Use care. Take photos if necessary. Just a few clips, maybe a couple screws but can't remember. And yes, the filler pipe is part of the tank assembly. After you refit the tank, don't...
