4JB1-T Oil Filters

[nig]

I know this subject has come up from time to time, but after a frustrating morning (3 litres of oil pumped out on to my driveway ) I can now say that Ryco brand oil filters are rubbish in this application anyway - the hub of the filter bottoms out before the o-ring gets any real pressure on it. Those 3 litres that I spent the next couple of hours cleaning up took all of 20 seconds to expel past the supposed seal on the filter

I have had good results with Repco branded filter in the recent past, but the last one I had seeped pretty steadly and left stains wherever I parked the truck, so I thought I would try something else.

I already knew Valvoline brand filters were also rubbish, and the Ryco looks pretty similar design so maybe they come out of the same factory.

So what are you guys using, and how happy are you with their ability to hold their fluids?

In 110000km Ive only had one filter leak but that was due to it being removed 3 times due the the hoses on the oil cooler leaking. Ive used ryco repco and Valvoline without real issue but for the last 50000km its all been valvolene. A lot of people use Sakura filters but they are not that common in NZ. Ryco are known to unscrew themselves on Isuzus and diesel and turbo only use genuine Isuzu filters but ryco on everything else for this reason.
Ive always believed Valvoline were good filters and would recommend to anyone. What have you heard to the contrary?

I always use MANN filters (chilean made), code 920/80. Any problem with them, I'm very satisfied.

About a 2 years ago I fitted a Valvoline filter, and it leaked pretty steadily - enough to put a puddle of oil about 5 cm in diameter on the driveway overnight, so I replaced it with another thinking this might have been an isolated example, and the next one leaked even worse - ie with the engine running you could see drops of oil collecting on the outside edge of the joint. So I tried a 3rd one with same results - at this point i decide that Valvoline had lost the plot & gave up on them and started using Repco filters.
I dont think Valvoline manufacture their own filters, and so the ones you get in NZ may be sourced from a different manufacturer to those we get in Oz. And the filters we used to get under the Valvoline brand here worked fine, they only went downhill about a couple of years ago. I will try to get a couple of pictures of the difference between Repco & Ryco filters later today, but I think there is a design flaw in the Ryco I did battle with yesterday.

A promised, here are is a picture of a Ryco oil filter:


and here is the filter that Repco sell for the same engine:


Notice the difference in the shape around the center. I measured them both - from a straight edge laid across the rubber ring the distance to the threads is 4.5mm on the Ryco vs. 6mm on the Repco.
Looking at the Ryco there was a circular scratch on the highest point of the center, suggesting to me that the filter had bottomed out on it before getting any pressure on the rubber ring.

[geeves]

Would you believe me if I told you that's the wrong ryco filter. The one pictured is for the pre 88 engine. The correct filter is z402.

[nig]

Just checked on Ryco's website - according to it Z402 is for the 4JH1TC, they list Z178A for 4JB1T on Rodeos from 90 through 02.

Rather interesting though that your info is different - makes me wonder if there is more than 1 spec. of oil filter mount on the 4JB1T engine - anyone got any ideas on that one? Mine is a late 94 model and this filter (and the very simlar Valvoline filter) dont seem to work on it.

By the way, Ryco's website is not bad - heaps of information

[walruz]

z402=4JG2 ;D

[geeves]

Only knowledge I can throw at this is the z402 is used on the belt drive engines which apeared in the bighorn and mu from 89. For some reason the jackeroo and rodeo remained with a gear drive engine so there might be other differences. My 89 bighor has used a z402 equivelent for 11 years

[James W]

and my MU uses a Z402 for the past 8 yrs

Maybe an error in the databook....

Do you still have the filter that came off?... that is always the better bet for a part numbers than any book

[geeves]

confusion rains
Just looked at the valvolene website and got
Mu ucs55 4jbi engine = vo56
Rodeo/jackeroo/bighorn ubs55 also with 4jb1 engine = v053
I have a bighorn and it runs the v056 I do remember when I first got got it I had a service done for warranty purposes and it got held up because the wrong filter had been ordered. They may be interchangable but you have to compare them in the shop to find out

I use a Z402 or an ROF-80something on my 4Jb1, it is my understanding that the TD rodeo have a different oil cooler setup that is different to the MU. I was talking to a guy the other day who bought a 4JB1 from the wrecker to put into his rodeo as the guy reckoned it would fit but on closer inspection, there were heaps of cosmetic differences between them.

For what it is worth, I use fleetguard filters on my MU as they are very accessible to me through work. They don't do an oil filter yet however I use their fuel and air and they are very well priced.

The centre spigot on the later filter mounts is significantly bigger than the z178a one.I don't think the 178a filter will even start onto the 402 housing.Check the big nut in the centre.It retains the oil cooler and filter mount onto the bottom bit.There's another seal between the oil cooler part and the bottom.In theory the filter should pull it all together when it's done up but I suspect that if the nut is really loose the filter will lock up against it without pushing the cooler down onlo the body.If that's too confusing [looks like it to me] I'll try and post some pix of the two mounts.I think I've got one of the old ones around somewhere.I've changed both of my motors to z402 filters.
Hope that helps,Harry.

Yeah I always used a genuine Jackaroo filter (4jg2) $27 for my 2.8 MU as the rodeo (4jb1) for aust was the wrong size and way smaller... must be the chain driven 4jb1's or something that have a different filter...

[tlyver]

I have an origonal Japanese filter on my 4jb1t and I can't find anything even close.

Its a strange thing with a seal inside that buts the threaded pipe from the engine. SO I got a AC Delco PF1298 and it looked identical to the origonal except there was not enough turns to actually seal the outside ring because the threaded pipe is too long.

However as long as the engine ran it was a goos seal. When it cooled overnight it let all the oil run out and resurface me driveway.

I have tried several (the ones from Austrailia cost me over a hundred and a half to get here) and htey are all the same...no seal inside and the input is about 4 to 6mm too small. My engine has a huge threaded pipe for the filter.

DRop me a line if any of the filters mentioned in here finally worked out and look as I have described this one.
Thanks

Apparently eth intercooled version of the 4jb1 engin ehas a different oil filter than the rest. I have tried to get a filter to fit my truck since I got it 6000km ago.

It is strange in that it has a seal at the end of the threaded shaft it screws onto. The pipe that pumps the oil up buts on a rubber seal inside the filter as well as its having the regular seal around the outside.

Are ya with me?

I am loosing it over this filter. Has anyone got an idea what th enumber might be? I tried a DELCO pf1298 and it was perfect except there was less thread insude the filter so the pipe hit the seal before the outside seal sealed. It was a mess.

Any ideas drop me a lilne [e-mail]

[geeves]

Is there a number on the original filter. I dont know the Delco filters but unless it has some aftermarket setup the filter will be a valvolene v056 for a belt drive engine or a vo53 for a gear drive. The vo56 is aprox 150mm high the vo53 120mm. You should be able to match these to localy available filters.
where are you

[mudgrip4]

May or may not be relevant as my trucks have been 1988 non intercooled 4JB1s, but that model takes Z178A filters. I've generally used Butler Auto mart ones at about $10 and not had problems.

Two things I learned from experience though after a couple of early oil seepages - I always pick filters with a wide flat o-ring (as opposed to semi-rounded) for better seal, and do the filter up pretty tight.
Works well.

If you continue to have problems with intercooler model filters - call the local isuzu agent and see what they fit - what factory spec in the isuzu book is (- that is if someone hasn't done this long ago..)

Hope this helps as it lists a couple of conversions
If you have a gear drive engine (pre 88 or holden jackeroo or rodeo) the delco number is AC061
If you have a belt drive engine (89 and later except the holdens) above its a AC066

[Demonic]

Tryed finding it on the www.clubisuzu.com website but its gone, Does anyone have a definite part number for a 2.8 4JB1-T oil filter?? (i hope this is right engine number for a 1990 Mu).
