R34 Cooling System Problems

[iseekool]

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

... or a recommend place to fix the issue

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.

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?

Oh cr*p i didn't take that into account...

Remove old piece, get new pipe, weld on, shove vac cleaner inside to remove any metal filings...
