    Nylon is great for fuel pipes and fishing line, but not sure about a relatively long/thin component under clamping pressure of the mounting bolts. Think I'll stick with my aluminium spacer.

    FWIW, its oil change time on the County. I've currently got the sump and filter housing off so it can grow a drain hole for the bypass filter.
    Definitely hasn't got one at the moment

    Query for those in the know.

    I have a 1990 Isuzu County, it is fitted with a single spin on filter (Ryco part no Z419). Quite large in size.

    What is the primary reason for people fitting the twin filter mounts? Is it for improved oil filtration or what?

    I can fully understand why you would convert your engine to spin on, if your engine was originally fitted with the canister style filter. They are a ***** to change.

    I used to work on JCB backhoes, they run a 4.4 litre turbo diesel. They have a service interval of 500hrs. So imagine that were a 4BD1 being driven at 100km/h every day for a total of 500hrs. That's a 50000km service interval. Even the older Perkins powered models had a 250hr interval. That's still roughly equivalent to 25000km. I've seen several Perkins powered backhoes running around with an excess of 10000hrs on the clock, still running, starting and digging no worries at all. They do pant a bit, but find me an engine that wouldn't with 10000hrs or 1000000ks on the clock

    Yes I will admit they are running 13L of engine oil for the JCB 444 and 11L for the Perkins, but thats not much more than an Isuzu

    Correct me if I'm wrong?

    I was going to pull my filter mount off and adapt to the twin style but I'm not sure there is really any need.

    Interested to hear peoples facts and thoughts

    This might sound funny, but I made mine out of hardwood. Been meaning to get one machined up to replace it, but this one hasn't let me down yet

    The 4he1 has a fairly large filter holds about 1 liter if my engine is as good as the stealer said its gunna out live me by about 10 times.Oil capacity is 13 L
    mine being 12L with mods to sump IMO the best option would be a centrifugal as the amount of crud they remove is incredible and just need to be cleaned

    IMO the reason for using a bypass filter is for better filtration.

    My 4BD1T originally had the full flow plus bypass filters. I bought a centrifuge filter to replace the spin-on bypass filter to improve the soot removal further, with the intention of extended oil change intervals using synthetic oil.

    Yes.
    Full flow filters remove the rocks (25-50 microns +)
    Bypass filters (the second filter in the twin arrangement) remove smaller particles, which still cause a lot of wear.

    Some engines (e.g. toyota [and probably some/all of the engines you are talking about if they have a single lube filter]) have a combined FF + Bypass in one filter element - but a lot of the aftermarket copies of toyota OEM filters don't.

    If anyone wants a twin filter mount I have one sitting in my carport

    Bit of an old thread but I'm at the same point and am wondering about this conversion. I have the old cartridge filter and have a twin filter setup sitting in the garage and am wondering if I should go to the effort of getting the spacer or just fitting a single spin on filter. The engine has a good 450,000km on it already and surely the damage is done already in terms of extra wear.

    those who have a td5 and have observed their engine oil realise the value of twin oil filtration.

    when I sold my D2 it had 375,000km on it and the engine appeared to be mechanically faultless , except for the engine accessories , which any td5 owner understands

    For the spin single filter conversion, you might need this:
    Spin-on Oil Filter Housing, 4BD1 - KLR Automotive

    For twin filter conversion you might need this spacer block:
    4BD1 Oil Filter Spacer - KLR Automotive
