It pays to use genuine oil filters!!

[mudbugga]

Got a 07 petrol Hiace van in at work which has had a Repco (Ryco) oil filter fitted.
It came to us with a bad engine knock in the top end. Took off the rocker cover and found all the hydraulic lash adjusters had all gone soft. Took out the cams and found that they had started to pick up from lack of oil and found the cause.
Some of the oil drain back valve in the filter had torn away and been pushed up to the head and blocked up an oil gallery that fed the cams etc.
Have stripped the engine down to investigate further and to see if any more filter bits got stuck anywhere else. Nothing else damaged apart from head, cams, VVT-I. Over 8g in parts alone.

The owner of the vehicle took the bad oil filter back to the Repco branch they got it from and they sent it to Ryco to see why it failed. Got a phone call from the company that owns Ryco to let us know they will pay to fix the damage.
Good to see that they are willing to remedy the situation.

If only a genuine filter had been used.......

Why wouldn't you class ryco as genuine? Just because this occcasion or do they have a bad reputation anyway? Whats best to go for, I've got a ryco in for the moment but thats coming out in the weekend for a new one.

i will admit i use genuine filters on my mercedes but that is more because the genuine ones are cheaper and easier to get hold of the copies are not guaranteed to fit and i have had that happen to me more than once

The reason a genuine is better (without going into design of the filters) is aftermarket types don't usually have a consequential damage clause. So it their filter fails and stuffs your engine they may pay for the oil filter only.
Genuine cover consequential damage, that is anything that has failed due to the filter failure.

After a BAD experience wih my old little bighorn 2.2 l non turbo diesel where the cheap filter I used did NOT have an anti drain back valve and with the filter mounted upside down (factory) the engine rattled badly every time I started it up.
After a day of this I changed to a reputable brand (possibly Fram or perhaps Ryco) and the rattle vanished.

These days with my Prado, I always use Semi-synthetic oil 10w40 and factory Toyota filters at nearly $50 each. I figure Mr Toyota's men have spent lots of money doing their Test Engineering and I will use their gear.

How's this for bad luck...
Another Hiace van, from same rental co as before, coming into work this week... you guessed it another failed Repco oil filter.
Thats 2 in 2 months. Both petrol vans (2.7L 2TR-FE).
We were expecting it in at work today but it hasn't shown up yet.

That's interesting because my isuzu hated FRAM filters and they were a hideous price too. It would take the oil pressure light about 6 seconds to turn off after startup. Enough that you were starting to wonder if it ever would.

Switched back to ryco filters and haven't had the problem since. My engine uses two, a main and a bypass.

There's a test on oil filters on the web somewhere, the factory toyota filter didn't rate that well on a cut open and inspect.

do you run bypass filtration to extened your oil changes... or is there another reason ?

It's the factory system, two filters.
Some factory filters (like some genuine Isuzu ones) have a bypass filter and full-flow filter built into the same cartridge.

didnt realise .. quite interesting
we used bypass filtration on very large plant machinery.. stuff with 1-5000 liters of oil
just to prolong service life...its almost indefinate (in our case) ... just do oil testing and add supliments as required
.. for me .. i do oil changes every 5000 km or 3 months... oil and filter .. used to send off a oil test as well ..(because we do apile of them so there free) just to keep tabs on stuff


im still tring to deside if im gunna go synthetic on my uz or not its had just over 3000 kms now since last rebuild ... and about 4 oil changes...lol ... might do that when it gets the new sump in the next few weeks
oh and always used genuine filters...i have a fram on this time ... oil pressure is fine... but ive cut a fram and a toyota uz filer open and the genuine has almost 2x the pleat's..... cant comment on the micron rating .... anyone got a decent microscope ?

News in regards to these oil filter failures...........
We have 2 more vehicles now to strip the motors because of this problem.

The company that brings Ryco filters into NZ, has them made in South Africa. That SA company is now under investigation as the filters (an entire batch, they think) have allegedly been sabotaged.
No one has an idea how many filters from this batch have been used and if there are anymore failures.

back in 1989, 1990'ish i got a sbc reconditioned and the engine reconditioner recommended not to use ryco filters as he could attribute 2 engine rebuilds that were due the ryco filters falling apart and clogging the oil galleries.
mind you i've used them since and had no problems.
