Does anyone know if there’s a way to identify a l67 block, I’ve just bought a supercharged vs and was told it had a full l67 in it (not just top end) but it’s mated to a getrag box and has dowls in crank. I’m sceptical it’s actually an l67 I...

    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.

    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

    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

    L67 Injectors

    L67 running rough and just realised I had l36 Injectors in lol. What symptoms would this cause due to the fact it isn't tuned to use l36 Injectors? Would it explain struggling to start/not starting and running really rough with lack of throttle response? Thanks
