    VX II S Manual
    Hey guys, I'm losing about a liter of oil every 3,000 or so, the car's only done 150xxx and there's no leaks or burning signs although It's building up oil in the cooling system, hoping that's where it's all ending up so I'm going to change the inlet manifold gasket.. my question is if i purchase the mace gasket set for vx what else do i need for the job? also it's probably worth replacing the pcv valve i'm told. where can i grab one of these? cheers.

    Very common issue. It's a pretty easy job, just make sure to grab some thread sealer for the manifold bolts and blue rtv for the corners of the valley. I only use Permatex high performance stuff, never had a problem. You can grab a PCV from any auto store or eBay.

    Keep in mind when the system has been running at lower than normal pressure for a while, after you fix it other components might go pop. Id suggest running straight water for a few days before you drop $50 of coolant in there.

    Credit where credit is due, a sound part from Mace means you never need to do the LIM gaskets again! Sale by sale this will become an uncommon job.

    Hey guy's, can you confirm what torque to do the manifold bolts up to with the alloy manifold gaskets. Is it 16nm (approx 12 ft lb) like the standard plastic gasket. It just seems so little torque to hold such a critical part together.

    Thanks

    Standard tension on the bolts will be fine, I have used a little more without issue. Just make sure you use either sealant or thread locker on the bolts so they don't come loose.

    As above. The only thing that I would add would be to re-tighten after the inlet manifold bolts after a week of installation.

    If you have any questions please don't hesitate to ask

    Kindest Regards,
    Steve

    Ok, but if I use thread lock / sealant on the bolts won't re tensioning the bolts encorage them to leak?

    What sealant do you recommend for the threads Steve?

    Cheers

    Make sure to use thread sealant, not locker, which is why it's best to re-tension after a week - the stuff stays wet and the silicone seals on the gasket will compress a touch.

    In theory, with the new alloy gaskets that MACE supply it shouldn't be so much off an issue with bolts coming loose as the expansion/contraction rates off the alloy gaskets will be very similar to the LIM unlike the OEM plastic intake gaskets.

    I still had to re-tension mine a skerrick 3 days laster using the Mace gaskets. It's the silicone seals stuck to the base material that seems to create the need, it gets squished good and proper!

    Does anyone have a step-by-step guide with pics, prices and parts & tool list on how to change the Intake Gasket yourself?

    Sorry to start up an old thread again. But what thread sealant have people used. One of the main brands (sorry I'm trying to find the page again) says final adjustment for the sealant is 4 hours. Other posts say after a week adjust the bolts again so I was wondering what brand/type they used.
    Thanks.

    Permatex High Temperature Thread Sealant 50ml Tube

    OEM Specified. Locks & seals threaded fittings. Resists leakage, vibration loosening, moisture, hydraulic fluids & diesel fuels. Lubricates threads for easy assembly & disassembly. Won't shred or wear like Teflon tape. Part may be repositioned up to 4 hours after application. Temperature range -65 F to 400 F (-54 C to 204 C) Contains PTFE.

    Suggested Applications: Head bolts into through holes, oil PSI sending units & sensor, oil & coolant lines, fuel fittings, rear axle fill plug, brake & power streering fittings.




    Also probably a silly question. But where do you put the thread sealer? Toward the end of the bolt or near the head?

    That's all I've ever used. Instructions are on the box, smear it round the end and it'll ooze up the thread as it goes in.
