I could not find a replacement r35 cooler and have been concerned about putting the old one back in after the disintegration of my engine.

I ordered the PWR replacement but it is less than half the volume so i wont be using it.

I have pulled out the old one and pulled it apart.

This is what i have done and i want to know if its too much of a risk to reuse it.

I have flushed it with fuel

I have flushed it with turps

I have flushed it with degreaser

I have attached one end to a garden hose and left it running for 10 minutes.

I have reversed the sides and again left it running for 10 mins

I have thrown it into the pool and left it there overnight

I have attached one end to a garden hose and left it running for 10 minutes.

I have reversed the sides and again left it running for 10 mins

I also understand that the direction of flow is from the cooler to the oil filter which should trap any micro particles that get in.

Anyone prepared to give further advice

I can't help with finding a gtr oil cooler (perhaps try Steve at Just Jap), but I never re-use an oil cooler from a motor that had a bearing problem. Too many little spaces in oil coolers, and it's a very expensive gamble.

I'd never buy or use a second hand cooler for the same reason.

yeah like duncan said. I personally would replace it. you've done everything humanly possible and as flow goes cooler to filter you should be fine (most systems go filter then cooler though so double check that?) but it's a big risk. there must be a better option for replacement.

we are probably all being a bit over cautious especially given the nature of your failure but I can't help but think if it were my car, i'd keep hunting out that replacement....

    • There are black hose clamps as well if you care. Plazmaman for example sells some: https://plazmaman.com/product/black-hose-clamps-premium-quality-stainless-breeze/
    • After using a protractor for an actually accurate assessment of what is required,  and by NOT using my uncalibrated eyeball I worked out I need a 25° silicone bend from the TB ro the MAF, but, my choice was either a 30° or a 23° (23° is a weird spec), so I grabbed the 23° one from Raceworks I also grabbed 1mtr of 3" straight from Just Jap, I needed 350mm, but they only had 300mm, or 1mtr lengths....meh Also ordered a 1/2" hose bulkhead fitting from fleabay, this has a smoothish mushroom looking head (they are designed for below the water line of boats) that will fit inside the bend, the hose bit and threaded bit looks to long, but nothing that a hacksaw cannot fix if required, the hose will then just get jamed on the threaded bit up to the retaining nut Fingers crossed and the unsightly amount of hose clamps will be reduced down to 4 once all the parts arrive 
    • Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.
    • I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.
