Hi all,

I changed my radiator hoses and coolant today. I was shocked. Seems the part where I attach the hose has rusted through. Any fix for this? (I've included some pics.)

Urgently need some help.

RB25DE - Non turbo

Cheers

Wow, that's not good.

Would say you engine hasn't been running any inhibitor in the coolant system. This stops corrosion of the metal and alloy parts throughout the system. Make sure you put some in once you've fix this up.

I would say the the steel tube will need to be cut out of the aluminium intake maifold and a new pipe pressed into place.

I would recomend an engineering workshop or competent mechanic.

oh god

i was hoping to do a coolant flush this weekend

i hope i dont see what ive just seen.

hehe - i was thrown back at the sight.. pretty nasty.

Nissan was quoting $800 for the bottom half of the intake manifold, as it is 1 piece (ordered from Japan - brand new item) they do not supply the tube end.

I probably can go to a machine shop and get a new pipe inserted, but its gonna be a pain taking out the intake manifold, i wonder if they can fix the issue with it still in place,,,,

Could possibly do it in place, but you risk getting metal shavings into the system.

The intake is really too hard to take off. Take the top section off first, then it'll be easier to get at the bolts that hold the lower section to the head.

After much thought and discussion with some mates I've decided to get the exact dimensions of the rusted piece and get a custom piece made up.

I'll then chisel out the rusted piece and press fit the new custom piece.

I wonder if stainless steel would be a good idea or not - I mean would it cause a bad reaction with the coolant etc?

I've found an engineering place nearby http://www.yann.com.au/

Any thoughts or pre-cautions?

      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.

      No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.

      Can you mount the ATTESA pump in other locations?

      Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!

      You think its the AFM? I know its a common issues on R32s. I find it coincidental how this issue raised right after cleaning the fuel system. As everything except the fuel system was fine before. I tried running it with the IACV unplugged but did not notice a difference and still stalled. However, the RPM gauge is not in the cluster right now, so I will need to connect the laptop again and use Nistune to check the RPM. I will check this weekend.
