Well, being the genius that I am, I decided that the easiest & cheapest way to install an oil cooler to my car was to buy one off eBay...

Please queue up in the line to the left in order to laugh at my expense.

And I do mean expense. :O

I bought an eBay oil cooler kit for $135 (posted) back in June with the plans of fitting it up & being awesome.

The pics looked like this:

: with the plan of routing an oil to air oil cooler core from a sandwich plate between the oil filter & oil to water oil-cooler sandwich plate thats already fitted to the block.

Then I received the 'item' some 10 days later direct from Shenzen, China. w00t!

This is what it looked like in the box when I opened it:

As you can see, it's got a relocation kit... not really what I wanted, seeing as though theres a poofteenth of nothing when it comes to space for relocating your oil filter in the engine bay of an M35. :wacko:

So I complained that I didn't get what I ordered & was contacted various girls named 'Michelle' & 'Brandy' in Guangzou to address the fact that I hadn't received what was in the picture (being a simple sandwich plate with -10AN oulets & a place on the top to screw in a factory oil filter...)

So they graciously sent me a replacement adapter to match what was in the photos.

Some 16 days later, I received the correct adapter & got to work fiting everything up...

Until I realised that the cooler core was about 300x300 in size & I couldn't get it to sit in an acceptable place inside my front bar where it would do any good...

Luckily, Just Jap is 15 minutes from my house, so I trotted down to see them & picked up the smallest of their oil coolers, which measured about 90 x 250 & had the -10 nipples that I needed.

'Cool', I hear you say!

Well, yes, everything was cool up until I fitted everything up to the car, with core in place above the intercooler & behind the grille.

Then the leaks started...

Every single one of the yum-cha AN fittings leaked.

That and the braided hose was so soft, it kinked trying to go around a gentle radius bend. :/

Luckily, I have a Pirtek dealer 5 minutes from my house, so I trotted up to see them & came away with two brand new braided hoses featuring -10 Proflow fittings.

'Finally', I hear you say!

So, it turns out I ended up using absolutely nothing from the original package I was sent! :whistling:

So the install was fairly straightforward from then on, with a couple of brackets supporting the core, a 90deg fitting on the nipple closest to the centre of the radiator, running the hose behind the bar reo & a 45deg fitting on the other nipple, angling the hose down past the i/c piping.

The hoses then wrapped around the washer bottle & back into the engine bay through the inner guard liner & met up with the sandwich plate.

Good news: the Proflow fittings don't leak at all! w00t!

The moral of the story:

Don't buy yum-cha oil cooler kits from eBay...

So you learnt the hard way, I don't know how many times I've told my mates not to buy those shit china kits!

Just go buy a core and buy the fittings and line from speedflow or who ever you choose, and make the thing yourself.

Your yum cha kit leaks because the fittings are not matched.

They are not hydraulic fittings.

Inside the fittings should be a 45 degree taper

Male and female respectively to couple together and make a mechanical seal.

Look at your relo plates, there is no taper at all.

The oil pressure just forced the oil thru the threads and leaky leaky.

Buy Australian , buy speedflow, don't winge about the money, because as seen here, you end up doing it right the 2nd time.

Good to see you learnt a valuable lesson and also thanks for a detailed post, maybe no guys will think twice before being Jew bags and wasting there money in china on inferior products that clearly will never ever work.

Lol. Good story man. Plenty of times I've been back and forth to pirtek.

Did you have any ability to read before and after results?

I've got an oil temp gauge ready to go on, but the gauge sender ports on the sandwich plate are in a spot that will make the senders interfere with the aircon lines, so I'm waiting on a couple of 45deg 1/8npt elbows that will angle them out of the way.

So no, I can't tell what difference there is now that the oil cooler is on there, but once the gauges are in, I'm planning on bypassing the coolant from the factory sandwich plate & having the new oil cooler doing all the work.

I'll report back once I've got results.

there was definitely a taper in the yum-cha fittings, but from what i understand now is that the angle of the seats is different... near enough is close enough in China they say. :wacko:

the cheap fittings also felt cheap... they just seemed lighter & less dense than the Proflow ones. In fact I was afraid they'd crack as I was doing them up. :unsure:

lolz.

I bought one a while back......sold it to some tard with a gold POS named Sunkist in Vic! :P

Just an fyi....if your after a good thermo sandwich plate I have a brand new Grex one sitting on my bedside table thats for sale....only issue is it has an R34 adaptor but you should be able to use the one you have just used for you sandwich plate.

Sooooo; did someone say Haydn's awesome Aussie spec oil cooler group buy? :whistling:

Sucks that you had a shite experience; at least you had the good sense not to persevere and potentially damage a motor.

Where is your trans cooler hiding?

Exactly the same spot above the intercooler next to the oil cooler.

It hadn't been fitted in the pictures

There's also a small power steering cooler wedged in just between the oil cooler & headlight now too.

Pay peanuts, you get monkeys. Apologies to Mr 20Valve. LOL

Maybe; but nothing ventured nothing gained. Someone has to take the risk every now & then.

If no-one had tried K-Sport BB Kits, or BC Coilovers they would've been an unrealised performance bargain.

  • 4 weeks later...

Have you had a chance to measure temps yet Hayden?

Considering doing this and trying to work out if the size you've picked is big enough, and if it's not where to fit something bigger :unsure:

To give you a quick idea - cars that I have logged when hot (ie traffic/idle/city driving - NOT giving it a boot) have logged oil temps around the mid to high 90s.

Cheers Alex. I take it that's without a cooler?

    • I am getting the same issue. Did you resolve it? I just got it after installing my new super coppermix and literally the same issue, new fork, new 18mm carrier, release bearing that came with the kit and replicated the exact same sound. 
    • If you like - I have the STL files so I can email em. There's a couple of gotchas (i.e the holes are not threaded so you might need/will need) to utilize some M3 melt-in threads for some of the points. However if you want to be super accurate, and are willing to remove your calipers and your SHOCKS it's a really good tool. You also might need to scale the part that measures the tyre width a bit wider. It defaults to a 7.5in tyre and I mean who is running that. Luckily with the magic of CAD this is very easy to rescale.
    • jeebus. glad you weren't under it while performing the stunt. Also thanks for the link to the wheel measurer, exactly what I needed
    • In the older stuff there were very significant differences 2wd to 4wd, for example Stagea had strut front end for 2wd and double wishbone for 4wd so it was not minor to swap. From poking around the 2wd v37, it *looks* like it might be more possible; some of the parts specifically have "2wd" stamped on them which suggests the platforms are more similar. You'd still want to start with a 4wd half cut to swap stuff from though. I'd suggest if you don't have a tune on the ECU you don't really need one on the trans either. Throttle mapping is in the ECU side (and you can always use a Roar Pedal if you want the throttle to actually respond to your foot), and really if you are happy with the stock power you probably accept the stock trans behaviour too....its all made to be "sporty" not racey.
    • So, updates. I have not washed the car since it came back from Tassie. I've driven it around a bit but not got around to actually sorting it out. I DID raise it because I cracked the rear bar leaving a hotel which was very distressing. Interestingly, the car drives more compliant now that it's raised a fair bit (5mm front, 15mm rear). Also noticed that my FR height was 10mm lower than FL. So that's now sorted out, too. I also bought this and had it printed: https://www.etsy.com/au/listing/1576422240/wheel-and-tire-fitment-tool-universal?ref=shop_home_feat_1&dd=1&logging_key=08f604d9fa4cc383550ba985e6ac85cd5cac7fbb%3A1576422240 Now, if I was smart I would have taken my brake calipers off to actually use this correctly but it was evident enough to me that in the region where the caliper was... there was nothing to hit suspension/guard/arm wise. So I'm going with "it'll be fine" after using the tool to hopefully very precisely measure the wheel clearance. Also while doing this, I had the very VERY bad idea of jacking one of the wheels/suspension arms up while the rest of the car was on jack stands. I did this to see how the arm would travel. This all was well and good until the car slid off the stands and went through a fence. So don't do that. Incredibly nobody was hurt and there was only minor damage to the rear bumper as the car didn't have far to slide, and had 3-4 wheels on it. The only damage turned out to be the fence itself which was easy to fix, and a little bit of damage to the fibreglass rear bumper trim. I had already planned to try a touch up paint kit to fix the time I drove into my garage door to see if it'd help in the interim before I get it fixed properly. I used the Dr Colorchip kit after looking online and seeing everyone talking about it. Yes it's made for chips and not huge broken missing pieces and I'll be 500% recommending it for stone chips after using it for stupid things like me. This took about ... 10 minutes and looking at the half assed photo the 30 second job I did on the bumper corner was almost perfect just by using the tiny little brush and painting it in. The sealact stuff to remove over-painting is really useful, so if/when I do it again I'll likely slather the touch up paint well over it and then clean it up with the cleaning solution. The wheels should arrive in a couple of weeks. I am still kinda confident after doing a stupid amount of measuring (and borrowing a set of 18x10.5+15) that they will not fit because I overlooked something, somehow and flew too close to the sun. ALSO R34 GTR guard liners do not fit on a GTT. I bought the undertray brake duct guides and had the wonderful problem of them not fitting my intake, my oil cooler and the liners themselves were even worse. Attempting to fit them won't work in general - You would have to cut them up as another poster mentioned as the bodywork is different on the GTT. At least I can try to resell them. So instead of cutting those up, I cut up my old already-cut-up GTT liners and extended them by using some PP plastic and drilling some 8mm holes for some nissan clips for the 'extra' bit. Because I was happy to cut them I was able to mount them pretty damn forward so I now have some semblance of guard liners, and the brake vents seal the bumper from the bottom. It sort-of-looks like this, to give some idea - If you look at the GTR and then the GTT this is when I realised that I needed to seriously measure as the inside of the rim area is entirely, entirely, entirely different and could not take any internet measurements for granted.
