Z9 oil filter instead of Z89A

[glenhendry]

I did engine oil change yesterday (chose Valvoline 10W40 Armour - $28-5L). I bought the legit Z89A (http://www.rycofilters.com.au/catalogue/part/make/LANDROVER/series/2000/model/RANGE+ROVER/part/Z89A) oil filter (AUD9) and because I know the Z9 (http://www.rycofilters.com.au/catalogue/part/make/LANDROVER/series/2000/model/RANGE+ROVER/part/Z9)filter to be similar and larger, I bought it too. I compared them on the bench and they look the same. The specs are the same too, except for the length. In filters, I think bigger is better and since it fitted fine, and did not protrude dangerously I am using it.

Anyone think this is a big mistake?
Is the filter specc'd to the oil pump?
The Z9 was cheaper and more available?
The Z9 was used on the Classic RR.


Edit: 2000MY P38 4.6

On some LRs there is a danger of the front axle contacting the filter when articulating the front suspension if the longer Z9 is used.

What did you put it on ? If it was a disco 1 it will be too long and get belted during axle articulation.....Goodbye engine oil.
I don't know about all models.

I have been using generic Z9 filters or equivalent in every Range Rover V8 I have owned , never a problem. The early Range Rover filters were even longer than the Z9, In the uk I used the Ford V6 engine filter (x19) as these were the cheapest. Only problem I have ever had was in the mid 1970`s when I had a 1965 Series 2a with a 3.5 V8 shoehorned in. There was not enough room for any oil filter, I ended up using one about 3 inches deep. Again never a problem
Always used 20/50 and change oil and filter very often.

Good info Wayne, i took a look under mine just now and confirmed that the only thing that could come into contact with it is the panhard rod, and I doubt it will move that far. Ill do some careful tests.

The million dollar question remains, why did LR change from Z9 to Z89A when introducing the P38, when it was basically the same bottom end block?

Standardised the filter across engine families as a Z9 length filter fouls the front diff at full bump with a 300Tdi in a Disco or Deefer.

This can be 'fixed' with judicious use of an angle grinder on the diff :angel:

FWIW I use either a Donaldson P169071 or Fleetguard LF3487.

These are synthetic media, super high efficiency/high flow versions of a Z9/AFL-1 filter (and their price reflects that)

A Z9 is fine on a V8 D1.
Never had an issue using them on my MY95 which sees the occasional 4wd park etc.

So the rich Folks who bought one could feel special as they were paying more ( for less)

I was referring to the 300TDI.https://www.aulro.com/afvb/images/imported/2013/02/1396.jpg

They didn't.
The Z89 was introduced with 3.9, because the newly fitted oil cooler takeoff "sandwich" moved the filter forward enough to hit the diff.
I don't know what happened when the new oil pump was introduced but I assume it also puts the filter in harms way.

Months later, the Z9 is performing fine and hasnt been hit by any P38 parts.

[PhilipA]

It will only happen if you say hit the bitumin after dirt and there is an unseen step up of several inches as often happens. Unless you live in Victoria where councils have plenty of money to neatly grade dirt roads.

Told you it would be fine, at $5 a pop it seems stupid to me not to use them especially as our diffs are on the left side and are well out of the way. Never had a problem using them on the two 3.9 Classics I have owned either

[PhilipA]

Hmmmm.Saving of $5 every 6 months Vs possible loss of $8000 if filter punctured and oil flows out.

Not good odds to me.

I would suggest you stick your head under a p38 and look at the room. If something is going to penetrate the oil filter it will be an outside object which could effect any oil filter. I dont know you, your car or what driving you do to give your opinion.
My cars gets their necks rung off-road as often as possible, and I have been doing so since 1976 always in a V8 rover. Some of us have not got money to flash around and for me every penny helps. I probably do 6 to 8 oil changes a year.

I did my oils two weeks ago and got the filter from super cheap. The price for the 89a was only two dollars more than the z9. Previously the 89a was around $20 but now they are less than $10. May be different in other states. They were the ryco brand.

[glenhendry]

I wheel the P38 pretty hard, I dont think a step-up from dirt to bitumen is going to flex the suspension more that what I put it through :)

[rick130]

FWIW the genuine ERR3340 is usually pretty keenly priced too.

It's been years since I bought one but they were about the same or a cheaper price than the Z89A Ryco.

I have Z9 on my D1.
the 93 [auto] has sandwich filter.and the oil filer clears the chasis by about an inch.
the 94 [3.9 auto] has the cooler in the timing case and the hoses fowl filter.

to damage it you have to hit or be towing something or break a mounting-and that never happens.

Z89a had non return valve-i think it would be hard to find a spin on filter that has no antisyphon flap these days..


Z9 are getting hard to get and its been some time since i seen $3.50 filters.
he idea was im brainwashed that the small filter flows oil quicker to the engine on startup.[re:I use a Z9].

my nissan RB6cyl-skyline.comes with a range of filters.Z9/Z115 was used as a oil flow FIX for vehicles that had that anoying oil light on at idle.
original is Z145a-you have to check if the oring fits on every oil change as the use different dia these days.
the nissan filter has no bypass valve-just a relif valve.the bypass is in the block.
last trip to the dealer and a check with my spare manual the filter superceeded to a tiny thing.Z442-86mmX68mm.oring was tiny.

I've done the same thing re the oil filters too.

89a is about $10 dearer last time I checked here in Benders; and personally, I'd rather the largest filter possible.

The 93 rangies stipulated an 89a; I know the Z9 is fine on them, with the amount of abuse i've put that car through!

I've had a z9 on my 96 for over 12 months now, on access there's plenty of room for when the bumpstop takes up more.

Phillip, you've been driving in Mexico with your eyes wired shut! The bitumen pavement is the one with all the bumps in it... brand new pavement in outer western suburbs are stuffed inside 2 years!!
