Hi All,

I recently put in my car for it's full service at my car dealership (who will remain anonymous for now) and along requested them to do an install of 2 gauges being oil temp & pressure since the service was going to do the oil change anyway.

Car service done, car gauges installed, car turns on, gauges go well everything is sweet, off I go down the road. About 4k's down the road in traffic (Going very slowly) I hear a "Pop" sound that sounded like I had driven over something but I felt no force from the steering wheel or movement in the car. I check my dash to see my Oil light on, I check my gauges to see oil pressure had dropped down to 0. I get the hell off the main road and onto a side street. Jump out the car and duck under the car to see oil EVERYWHERE, pop the hood and found my oil filter sitter there on the steering column and the sandwich plate dangling there by it's wires along with alot more oil everywhere.

I lift out the oil filter after it had cooled down and found the screw the connects the oil filter and plate to the engine had a good 1-2mm piece of metal still in the thread of the screw that it had ripped off from the engine bay.

I call up the dealership who calls up his engineers who will be taking another look at it tomorrow. But for now, any ideas on what caused this would be great? Faulty parts, faulty engineer install, worn out threads? Anything and everything would be great to know.

I was able to reattach the oil filter itself without the plate, the dealership guy was kind enough to bring me some oil, filled her up and is now waiting back at the dealership's shop to inspection tomorrow.

Before the "PoP!";

Car - Nissan Skyline R33 GTS-T 1996

Gauges - Autogauge Oil and Pressure + Sandwich Plate

Oil pressure - 20 PSI on idle, 60-80 PSI in rev range of around 2000-3000 (was in traffic)

Oil Temp - Still very low as the car was only on for about 10mins (was able to move the oil filter not to long after stopped without it being to hot)

Full car service was done before the gauges.

After the "PoP!";

do nothing more and dont drive or start the car.

insist that the dealership have the car picked up via flat bed tow, and fix their bollocks up at THEIR cost!

thats some seriously dodgy shit, even if it was a part failure and not a workmanship issue, the workshop still has to stand by the issue and warrenty it.

you'll be lucky if there is no spun bearings....

This looks exactly the same as what happened to my mate. Looks like the same sandwich plate too.

The reason this has happened is that the bronze coloured adaptor has been overtightened. As it is tightened it tries to squash the sandwich plate but can't, obivously the next weakest point will go. Unfotunately this is the factory thread that the oil filter attaches to.

It is easily solved though as the oil filter thread and flange is actually bolted to the block and not part of it. You should be able to pick one up from a wreckers etc. It is a bit of a pain to swap it over I think but it shouldn't have caused any damage to the engine. My mates one came off at full boost in second gear. As soon as we heard it blast off and looked in the rear view mirror the engine was shut off.

I think he may have ended up getting another sandwich plate but I will try and confirm that.

Good Luck.

The issue is actually with the adapter, more so than the over tightening. You can see it only has about 2 turns on there which is no where near enough when you tighten it up as all the strain is on the last 4-5mm of the thread, rather than over 15-20mm.

You can see how much thread is left, more than enough to still get an oil filter on there from what you've said.

They should have picked that it wasn't right and not done it in the first place. I know of guys on other forums who immediately picked up this issue when installing other china oil products, and they aren't professionals.

Do not reinstall that sandwich plate, it's rubbish.

I had the exact same thing happen to me (funny thing is the sandwich plates looks identical to the one I tried).....luckily it happened as I was installing it.

I was able to screw the filter back on with out the sandwich plate. and just bought a relocation kit and oil cooler.

The kit has the threads for gauge senders where the Oil filter attaches too.

And with the price of oil cooler/relocation kits these days its well worth it.

i don't have no idea why people over tighten oil filters? :( ( :)

In this case it is not a case of overtightening the filter. You need the adaptor to be fairly tight otherwise every time you take the filter off the adaptor will come with it and make extra mess. I think the main problem with this kit is the bronze adaptor. I think the machining of them would probably be to the correct specs but they must coat the metal in the bronze material. Just to get my mates oil filter to screw on properly we needed to run the thread over a wire brush on a bench grinder. We should have stopped there but hindsight is a MF and you don't always think about these things when you are doing the job.

From memory there was enough thread on this adaptor but the overtightening of it literally tears the standard oil filter mounting thread apart as it must be a weaker metal.

I think my mate was able to screw a filter onto what was left of the standard thread, slam in some oil and drive it to a close workshop.

Unfortunately the sandwich plates appear to be one of those items which fall into the 'you get what you pay for category'.

Thanks for everyone's input, I got myself a Greddy Filter and got it on.

One quick question though, what kind of PSI should be running through when you doing around 4000rpm.. and what is the MAX psi I should be seeing?

As people have said it's not the fault of the workshop because you provided the part that caused the failure. When i installed mine i found the same problem with one kit so i order another kit that was also a cheapy and that one had a longer adapter fitting. I'm in the process of removing the sandwich plate and installing a removal block that completely removes the oil filter assembly and then remote mounting the filter. The SR boys have been doing it this way for quite a while because of the problem that you encountered with the snapping of the cast oil filter fitting.

Here's a picture of the SR one, my brother (GROWLY Custom Machining) and i designed the one for my CA18 and made it on his CNC machine centre because no one in the world made them and it'll be finished this Sunday (just have to cut the o-ring grove).

Shit i just bought an autogauge oil pressure gauge including the sandwich plate too from Just Jap. Is there anyone else that has this combo installed without a problem? Whats a good brand sandwich plate to get? Greddy, the only one?

The sandwich plate is probably fine you just need the thread on the bronze adapter to be longer/deeper. A fittings shop like enzed might be able to match something up that will work for you but I wouldnt bet on it.

But to be safe I would just get a trust/grex kit. Just installed one the other day on my 25 and cannot fault it.

Any idea who sells them and how much? Also how much do filter relocation kits cost?

    • My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.
    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go.
