Hi all , I've been using Ryco oil and fuel filters since forever but they are now being made in in Great Wall land and I think the quality and standards have suffered .

There was a thread started by Cubes about oil filters back in 2005 and rather than revive it I'd like to hear about others experiences , in recent times particularly , with oil and fuel filters .

In another thread I mentioned I got persistant fuel leaks using the made in China Z201 fuel filters but only at the inlet tube - which is a slightly smaller diameter than the outlet one .

These days I suspect the anti drain back valves are doing bugger all in Ryco Z145a oil filters as I get a slight momentary valve train like noise at cold start up that I'm sure didn't happen in the past .

Unless anyone knows of anything better I suppose I'll try genuine Nissan oil and fuel filters for my R33 , it would be good to find them made in Japan but thats a lot to hope for nowdays .

Thoughts ? Cheers A .

Time to change your fuel hoses, those OEM ones are probably hard as my toilet seat.

If you think those yum cha Ryco filters are horse shit made by my ancestors or cousins, just go buy OEM problem solved.

How hard is your toilet seat so we can compare?

I use ryco oil filters and don't get any startup noise. My lifters were stripped and cleaned 3000km ago

lol maybe I was a tad harsh... but I see many R33 still using their stock fuel lines (hence the leaks). EFI hose is like $8 per meter, why not replace it? I highly doubt a 0.5mm difference is to blame.

In terms of oil filters, that start up noise I cannot imagine it being related to just an oil filter. I've used Ryco and now just use Cooper ($5, meh lol)

The details of the leaks was in the other my other thread . I DID buy brand new 5/16" (7.94mm) EFI hose and I DID use the OE Nissan fuel line clamps and its the NEW hose that leaks on the garbage grade Z201 fuel filter . I had to refit the original hose below the filter and it doesn't leak now . This hose is not RS by the way and considering its in real good nick where the clamps were- and are again .

The PRC Z201 is supposed to have 8mm tubes either side but only the outlet one is . The inlet side is slightly smaller and it is out of round as well , both sides are . The inlet was 7.91 to 7.93 and the new 5/16" hose is not exactly tight on the filter outlet or the fuel rails inlet . When you screw up a genuine clamp that tight that its beginning to physically crush into the hose but you can still twist the clamped hose on the rail it doesn't inspire confidence , using the original hose everything is snug - even on the undersized POS Z201 inlet tube .

I decided to put money where mouth is and buy a genuine oil and fuel filter from John Robinson Nissan at Rockdale , they do the Nissan import bits in Sydney . For the record the fuel filter is Nissan 16400-41B1A and the oil filter is Nissan 15208H890C and cost $57 .

The fuel filter fittings are exactly the same 8.03 mm and ARE round . To blow through there is NO resistance at all where in a brand new Z201 there is .

If I didn't know any better I'd say the genuine article is a fine mesh strainer , the invoice quotes "Strainer ASSY-Fuel" , where the Z201 uses paper cartridges . If I can find a used genuine filter I'll cut it open to see what Nissan thinks is best . From RIPCO a Z201 bites you around $28 where Nissan wants ~ $36+ GST . For oil the Z145a was ~$6 and genuine $15 and a bit + GST . Must be interesting making an oil filter and sending it half way round the world and making money retailing it for six dollars . I'll be paying the extra tenish dollars and fitting what the manufacturer uses thank you .

wow... I pay like around $15 for a Ryco filter around my hood..

Interesting you have leaks, I've always just used cheap shit on all my nissans and have never had a leak.

GUD Automotive has only in recent times outsourced manufacturing to PRC . Google Ryco filters made in China and read about quality control or the - yeah you know . Certain lines of their filters are known problems and trying to fix this looks to be driving the local distributors crazy .

Your calls but my fuel and lube systems are worth more than $57 and having fuel pooling on the ground isn't healthy .

Lastly the boxes have in ant sized print made in Japan not the other joint nearby like Ryco ones do .

Don't know if this one I pulled out of my r32gtst is oem but it's definitely a paper filter inside.

...the brown stuff is rust, after my fuel pump died I discovered the large o-ring seal at the top of the sender unit must have been installed incorrectly, as it had a kink and squished flat spot, it appears to have been like that from new.

Yes the rust was from the fuel tank and you should have seen the pile I removed from the tank, no wonder the pump failed.

Jecs would be Japanese but not sure if standard , looks like it needed replacing a long time ago .

The current genuine filter top wraps around a rolled edge at the top of the can , the opposite to your one .

Quite possibly is original, our family imported about 5 skylines, all low mileage and totally stock as fare as I can tell. This particular car still had the 100kph over speed warning attached.

The Chinese made Ryco filters seem to be better quality than those sourced from other countries: http://www.repcotrade.com.au/go/news/important-quality-message-from-ryco

They haven't been made here for years. I personally use a K&N oil filter (made in the USA).

In terms of oil filters, that start up noise I cannot imagine it being related to just an oil filter. I've used Ryco and now just use Cooper ($5, meh lol)

If the anti- drainback valve in the filter isn't particlularily effective (or completely missing, as is the case in cheap generic filters), oil will have to first flow through the filter before it gets to the engine. This momentary lack of oil isn't good, and can explain cold start noise.

The issue would be that your oil pump has to prime then fill the oil filter before any significant oil pressure got to the main gallery / bearings / valve train etc .

The usual process is that countries like this offshore manufacturing because they cannot be price competitive with countries that have pathetic wages and conditions . Oh , and the mass market buys on price too .

This is not to say that the most expensive items will always be the best quality ones because as we we know manufacturing cost often has little bearing on retail price . The burning question is why has not the price fallen if manufacturing costs have ?

Anyway I think if people are going to be a bit serious about expensive oils and PULP fuels they should extend this towards good filters as well .

    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
    • Well they got my money but they are not getting my gearbox ! 
    • It's needed for rolling idle up, and I think it is a decider on VCT also.
    • I mean, not really. Link ECU's can absolutely still have errors from the ECU thinking it's getting a sensor it's not expecting. I would imagine the speed at the ECU level in Nistune does absolutely nothing anyway? I assume the ECU does not do any fancy TC stuff with regards to front+rear wheel speed or anything of that like anyway. Someone who uses Nistune may be more fluent in it.
