  • Intro (from the US)

    Hello All,
    Well, we're now officially part of the Monty Club! I flew down to Vegas last week and made my way up to beautiful St. George, UT to pick up a '03 Monty.
    I drove back up to Seattle and am really impressed with handling, mileage (previous truck was an 80-Series Land Cruiser, so this is a huge improvement...) and comfort!
    I spent my weekend replacing front brakes as they were getting pretty tired but had to get it to a shop to diagnose an emissions issue as we failed the smog test.
    Initially suspected a faulty oxygen sensor, but this is what the shop had to say about it:
    "Failed emissions due to lean bank one and bank two codes (P0171 and P0174). Scanned computer, found long term fuel trim stuck at 12.5%. Found vacuum leak at intake manifold plenum valve assembly, recommend replacing this part to correct lean condition"
    Unfortunately, this is a $900 part according to the tech, another $500 labor to get it replaced.. Before I commit that kind of investment, I figured I'd ask here first to see if anyone has had any experience with intake vacuum leaks, troubleshooting, etc.? I am considering driving it through the winter as is (no driveability issues, MPG's may be up a bit but not too worried about that), and when it comes time to do timing belt/water pump in the spring just rip into the intake as well and see if I can find an issue or leaking gasket to cause this issue. There is an exhaust gasket leak as well by the way, don't think that contributes to lean running though?
    Anyway, hope someone may have some input. Otherwise, happy to be part of the club and sharing in the collective knowledge on these forums.

      Hi there, there is no manifold vac leak problems with this model Monty/Paj, I would find where the leak is exactly and wipe some silicone over the join as a temp fix until you can fix it properly. It may of happened when the last Major Service was done which requires the manifold to be removed to replace the spark plugs? Welcome to the forum.

        Hey, thanks that is awesome! I'll definitely have a look at it again this weekend and see if I can pinpoint the leak. Would it be the intake that results in the lean condition, then?

          manifold leaks

          Yeah, its just like hobbo says, just loosen the intake manifold bolts / studs and inject some silicone betwen the manifold and the head face, then that will stop the inrush of air, that then makes it run lean, has to the exhaust leak, check for loose bolts around the leak and a quick tighten should cure that too.
          any how best of luck and welcome to the club.
