Remote mounted oil filter and cooler on ZD30

I started thinking that it is a pain to change the oil filter on the ZD. If I fit a front mounted intercooler it will be even more difficult to get at the filter. So why not fit a remote mounted oil filter and possibly also an oil cooler.

I have seen a photo of such fitted to a ZD on another site, but can not find out what has been used to adapt at the ZD30 factory oil filter screw in housing to then allow hoses to an external filter.

Has anyone got any idea if there is an adapter to screw in where the factory filter is, or if it is the same as on another vehicle etc.

OK it seem nobody knows much about it.

Does anyone know what standard or non standard fitting the ZD30 oil filter screws into. Is it unique to only this motor or anyone know if there is a way to adapt to fit another filter housing and adapter plate to pipes?

"Hello we didn't do it. It was done by customer"

Pity the guy who owns the vehicle is not on this forum as it is an interesting unit with a lot of unique build ideas. It is a big 6 wheel drive ute with massive camper canopy on the back and powered by a CRD ZD.

I wonder if anyone on the forum knows the owner, Allan?

I am sure I have seen this vehicle before, perhaps they were passing through Perth last year.

Is this what you are talking about???

I have one of these on my TD42, which feeds my remote mount bypass oil filter. The one listed is not likely to be the right thread for the ZD30, as I don't know what that is. But if you find out what your oil filter thread is, then that will be that you need.

I would have to give it a bit more thought before I used it, if it was the only filter in the system. Size of oil lines, length etc, may have an effect on oil volume and pressure. Not sure about this. In my case with a twin filter housing that is not a factor.

Thanks Shayne,
yes that is exactly what I am trying to find, but the ZD30 has its own type of filter housing that you put a cartridge filter into rather than the normal spin on type that seals with a flat face gasket. This unfortunately makes it hard to find anything to fit. Not only the central thread but the housing screws on a large outer thread and has a big internal O ring seal.

I also found that the ZD30 had very high oil pressure like 110psi and many of the cheap oil filter relocation kits will not handle this, which could end badly.

Right. I have just googled it, and see what the issue is.

Hmmmm............


Maybe in the too hard basket I think. I would give some thought to leaving it there, and using other ports on the motor for supply to a remote filter set up. It will still be tricky to get to that filter, but if you are changing it less often the pain is minimilised. That will also remove any concerns about volume and pressure needed for a full flow filter.

I have added a few photos in the previous post. Having a better look as I found these photos, I am wondering if they have as you say left the filter in place and added an additional filter connecting from the oil cooler body.

Or they may have used the housing to adapt to make their own offtake, but it would need to handle 110 psi.

OK after some more investigation and discussion in another thread, I hve a bit more detail on the remote mounted filter adapter and filter mounting.

http://www.patrol4x4.com/forum/3-litre-zd30-crd-engine-82/engine-oil-cooling-216609/

Thanks Craig, I got onto Diesel Central

Now firstly from the discussions and advice from Old Mav and others in the above linked thread, I decided it is not worth pursuing this for the oil cooling aspect and that may even be detrimental for my current set up and use. So I'm only aiming at having a larger oil filter that is easier to access for filter changes and possibly as a point to fit a pressure gauge and maybe a temp sensor.

I got in touch with Diesel Central and they do indeed make an adapter to fit the ZD30 screw in filter on the motor. This adapter then provides EDIT: AN-12 fittings for braided stainless 11/16" ID hoses in and out.
$230 bit expensive but it is a very specific filter for this motor and hence produced in low volume.

Then the remote mount filter pictured in the first post will adapt to a large Z334 which is a combination full flow and bypass oil filter used for the Toyota 1HZ-FTE motor so at least it is common and easy to get hold of.

$225 for the holder plus fittings and pipe work is going to be a bit pricey and I have to wonder if they are available through some other source.

Lots of info on here if you do some digging, and while most of it is for the TD42, the theory is the same.

A bypass filter will filter a very small amount of it, to a very high level. It cannot supply the oil supply needs of an engine, so must be run in conjunction with a normal full-flow filter. So you would have two filters instead of one. The higher filtration level allows much longer service intervals. As an example, with quality semi or full synthetic oil, the TD42 service interval of 5000km can be extended to 20,000km or even longer. Oil sampling is the best method to determine oil life.

The ZD30 has 10,000km intervals already from memory, so perhaps that will be enough for you and make it not worth the exercise. An individual choice I suppose.

Have a look at Amsoil to give an idea of what a twin filter remote filter system looks like. It would be an easy option, but the filters were expensive when I priced them. The bypass filter I use is a Baldwin B50 (equivalent to a Ryco Z8), and can be bought for about $25.

In your case you would need two filter heads, one for a normal filter, which you have identified above, and one for the bypass. The threads are different, so you cannot mix them up.

Western Filters in Sydney sell the remote filter head to suit the B50 & Z8, so have a look at that to see how it works.

Ok cheers, yes that explains it. So the bypass is just filtering a small portion of the oil but I gather that is gradually going to clean the whole volume to a higher level, lower micron size. I did just look up kits and found the Amsoil but seems that it only fits their brand of filters, kit of twin bypass adapter is $480 and pipework and adapter is another $250 plus filters, so they aren't cheap.

The ZD is also 5,000 km interval so particularly on long trips, like I did 28,000 around Australia. Oil changes became a mission to find a suitable place to stop and change oil then drop off the used oil at a disposal point and buy more for the next change.
 
#19 ·
Are you still doing 5,000k oil changes? I'm a bit mystified at this if you are, I have been on 10,000 service periods for years now and my oil is clearer at 10,000 than it was at 5,000 years ago.
 
#17 ·
Also just read up more on the filter for the adapter that Diesel Central have specified, the Ryco Z334 used on the 1HZ-FTE is actually both full flow and bypass dual stage filter built into a single canister. It is an expensive filter like $35 but is very big compared to the tiny factory filter element and if it does like you say filter fine as a bypass and provide full flow, then that's a bonus.
 
#18 ·
i wonder if the 12mm size hose is too small to provide enough oil flow rate? as we are talking about the resistant for the oil to travel such long distance along the 12mm size hose. the longer the hose, the more resistant for the oil to flow through.
 
#20 · (Edited)
Its AN-12 so not sure if that's actually 12 mm ID or just a code number size. I might look that up.

EDIT: thanks patrol97, good point I looked up more detail on the hose and fittings size then went back and edited the size in the initial post above AN-12 is braided hose internal diameter 11/16", 0.6875, 17.46 mm
minimum fitting bore 3/4" or 15.44 mm ID so quite a bit bigger than 12mm.

That is a CI-4 Plus spec oil Geordie. High detergent level for modern diesels. One local oil distributor told me that these spec oil have such high detergent levels that they are often called "dispersants". This could be why Geeyoutoo has good results with it keeping things clean.

As for the oil lines and filter sizes, the bypass filters can only flow a small amount of oil. The inlet on the B50 & Z8 is 1.5mm. So no need for large oil lines for them. It would be a different matter if the lines were also supplying the full flow filter as well. I have small lines, but if only system is going to supply both, as yours may well be, then the bigger stuff will be the go. I would think that Amsoil specs would be a good guide. As you say, not cheap, but installation is a one off expense. My issue was the cost of replacement filters, as I think nothing else fits their filter heads. You would need to check this out to be certain, but I did not suit my application.

As for your Z334 being both full flow and bypass, I dunno about that. Not sure what comparison could be made to a dedicated bypass filter. Oil sampling would be the answer to that.

Thanks,
regarding the oil filter, the kit from Diesel Central is looking good, I initially balked at the price but as I started to look at getting the components separately, for quality parts Speedflow hoses etc, I might save some trouble and buy their kit.

I looked at the Amsoil dual filter set up but ends up about $800+ and is quite big with separate bypass and full flow filters. The Z334 that Diesel Central use seems like a good compromise, it is much larger than the factory filter and designed for a larger engine, so that is one plus, it isn't cheap like a Z9 but talking to a guy at a local filters specialists place it has much better filtration specs and the built in internal bypass filtration not just a bypass spring valve which some cheaper filters have.

He actually said guys were fitting cheap spin on adapters on their Landcruisers so they could run the cheapest Z9 but there was no way he would run anything other than the best specification filter on such an expensive to replace engine it is just false economy.

I read a bit on the Ryco website about the dual stage bypass and full flow and they specifically mention this filter but don't give any flow rate or filter efficiency specifications away. At least this is also a common filter available Australia wide in every place that has any Landcruiser parts, so I wont get stuck without an available filter.

If I am travelling long distance, I can always throw in the original factory filter housing and a ZD30 filter as a spare, just in case of a leak etc.

It will probably increase my total oil capacity by about 600ml to 1L. I think the filter or the hose adapter also has an anti drain back valve so it doesn't empty itself when the motor is off, being mounted up higher than the factory filter location.

So far, if I can afford the price then this is looking like a good set up.

Use it as a main oil filter system, the hose will be way too small. At 3000+rpm, it won't be able to flow enough oil through

This is a kit designed by Diesel Central, for this engine and high hp applications, so I will ask them about the flow and hose size and lengths but for now I'm assuming they would have thought about it.

The hoses are a lot bigger than I initially thought so should be more than adequate for the full flow job. The size they supply is AN-12 stainless braided hose internal diameter 11/16", 17.46 mm. The Speedflow fittings are very good for having neat bends, fittings with straight through bore with very little restriction as that is what they are designed for.

Do you reckon that's not big enough?

Asked my dad what filter his Prado runs - it is the Z334 (I had a hunch it was). On his engine, Toyota specify 5000km oil changes. Not sure that really tells us anything, but a bit more info anyway. Oil sampling would be the ultimate test of it.
 
#33 ·
FYI, i use Z334 for the Prado's 3.0 TD engine. it need to be changed every 10,000km. and oil change is 5,000km.

bump

anyone gone down this route with feedback?

after looking at a friends setup on his Silvia (i know petrol and not a 4wd) it has me curious. he has also added a cooler which he comments made a big difference to cooling.

cheers

The price for the ZD30 adapter and rest of the parts has stopped me at the moment. But with my new pipework for the front mount intercooler, I have the turbo rotated facing down right in front of the oil filter so it is going to be very difficult to change oil filter. I am still budgeting slowly getting there.



Bought one from ebay with a cooler. Just not fitted it due to time. Hope to get it done this weekend. Removing the filters is just a ***** of a job lol
Tweak101 was that adapter for the ZD?

the best way to do is to install an oil pressure gauge. measure the pressure "change" before and after the extension oil filter installation.
