    L67 Pulley Size

    I have an l67, recently put on new heads and it's running well with a 3.4" pulley. I plan to put in high ratio rockers and a mini blizzard w2a. My question is do I need a dyno tune to drop to a 3 2" pulley or can i order a mace memcal or a memcal from a reputable l67 tuner? Thanks!

    L67 Timing Chain

    Will be changing the heads on my L67 very soon and was just wondering if it's worth changing the timing chain at the same time? The car has done about 260000kms. How long do these chains last? Will replacing it pick up some lost power? And is there a guide on here to do it? Cheers.

    No one in tas wants to tune a v6 unless you go all out and buy a haltech :/

    Engine Build

    Okay thanks! It's an l67. It would be easier to swap but getting a hold of an l67 is hard in tas and quite pricey

    Engine Build

    Ahhh might explain the knock retard I was getting on my old l67 I had with forged pistons. There was massive clearence, could probably fit a knife down in. So if I were to rebuild it even with oversize pistons it will run off the stock memcal?

    Engine Build

    And I'm guessing if it would like a rebore but you just hone it and put new rings in it itll just make things worse?

    Engine Build

    Hey, just wondering if doing a rebuild when is a cylinder bore necessary? And if a bore has to be done say 20 or 30 thou over, If using OEM oversized pistons is a tune required? Or is the oversizing negligible? The engine has 256xxxks in it and am not sure whether to hone it myself and re ring...

    I will do the first compression restore treatment test for you guys!

    Going to revive this 6 year old thread. Having low comp on my l67 with 256xxxx is on the clock. I'm wanting to use additives for a while to save money and put of the rebuild. What's the best additive that will work? I know its rings because it was evident in a wet test. Also can I just re ring...

    VY Idle Vacuum

    Hey guys recently got a VY l67. I've done a decent sized service since getting it. Done lim gaksets, replaced charger gasket, charger ubend gasket, tb gasket, PVC gasket, spark plugs, oil, coolant, thermostat and o2 sensors. My main concern is it still doesnt seem to pull a good amount of...

    Lean Cruise Settings

    What's the best settings for lean cruise? Can I save fuel by setting road speed to say 55 rather than 70 and changing the afrs from 18.1 to 15.4?

    [VR-VS] Install a catch can on a ecotec V6

    Alright so im best to run the can to under the TB but is 1 rocker cover sufficient for now?

    [VR-VS] Install a catch can on a ecotec V6

    Old thread i know but is this sufficient? One pipe going from rocker to can and venting to atmosphere? Blocked the pcv valve but do i need to unplug it from the TB and block the vacuum line and the where it plugged under the TB?

    Fuel Consumption Issue

    Nah the valves weren't sealing Alright cheers

    Fuel Consumption Issue

    My AC is off. Compression is fixed. I got a wideband in and my fueling seems somewhat okay but when cruising it keeps swinging from the 13s to 14s.

    Fuel Consumption Issue

    I have an l67 and it uses a decent amount of fuel. At idle in park qhen warm uses 1.9-2.2l per hour on the display and in drive uses 2.2-.2.6l per hour. I've read it's meant to read around 1.6? What things could effect my idle usage? I think idle usage pretty much reflects driving usage which is...

    L67 Fuel Consumption

    Alright cool. Just not sure if theres other issues causing the high usage or if it's just because of compression is all

    L67 Fuel Consumption

    Some say 17l per 100 is heaps for what's wrong with it and some say that it's normal for what's wrong

    L67 Fuel Consumption

    Had to ask again because I've been given different info from mates and stuff getting kinda confused on what to think :///

    L67 Fuel Consumption

    I have an l67 with 2 cylinders reading 60psi. I'm just wondering if 2 down cylinders and random misfiring on the 2 would be the cause of high fuel consumption? Averaging around 17l per 100? If I get the cylinders fixed will my economy dramatically increase or would something else be causing it...

    Lost Cylinder Compression

    Alright I'll take the rocker covers and wind it over to see if they all lift the same. If they do I'll take the heads off and fit these others on. If it's still got low comp then god knows. Cracked block it is

    Lost Cylinder Compression

    Well on a cold start the vacuum drops really low and the engine rumbles before vacuum picks back up. It idles smooth in park but crap in gear

    Lost Cylinder Compression

    I posted them, what do you make of them?

    Lost Cylinder Compression

    Is there anyway to post video? I have a few videos of the vacuum gauge at cold start and shifting through park and reverse

    Lost Cylinder Compression

    Nah engine has been rebuilt twice. Mechanic said rings but it was clearly the head. Its probably warped or cracked. I got another set to put on. Do you reckon the low cylinders would cause a major bump on fuel consumption?

    Lost Cylinder Compression

    Like a really big hit in consumption or only a little?

    Lost Cylinder Compression

    Have a recent rebuilt l67 and lost compression in 2 cylinders. Both around 60psi. I have new heads to put on it but was just wondering, if 2 cylinders are down on compression would that cause a major increase in fuel consumption? Like 16-18l per 100 average? Thanks

    Car Struggling to Start

    Pretty much expect forged rods and pistons. Injectors must of been knock offs because they were only $160 so I got a set of used genuine Holden ones. Got this fault when scanning though
  33. DeathSammich

    Car Struggling to Start

    Car was always rebuid, new forged rods and pistons. Injectors are Bosch

    Car Struggling to Start

    I believe it is the l67 tune but I could of mismatched them? Code on it is dblco ddrh 2640? Don't know if it means anything
  35. DeathSammich

    Car Struggling to Start

    Nope it was a fairly new filter
  36. DeathSammich

    Car Struggling to Start

    Well I must be because the engine tries to actually go like it stumbles and stuff but won't actually fire properly
  37. DeathSammich

    Car Struggling to Start

    Yes they're standard l67 injectors
