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?

      [HOW-TO] Winter Steam-Clean & Odour Removal in 30 min

      Each to their own I guess  Me, I put just as much time into cleaning inside of the cars as I do on the outside As for getting wet, it is really no different than steam cleaning the carpets at home, apart from the cars carpet dries alot faster than the house, again, I only do it in the hotter months and leave the car opened up for a few hours As I only do it yearly, it is just before I do the diff and gearbox service, so I clean the carpets, then it's up on stands, wheels off, service, clean the undercarriage,  grease the bushings and do a nut and bolt check on everything  Disclaimer: I typically had all the time in the world to kill when I was working 🤣, so spending a full day or 2 cleaning, serving and "looking at stuff" was,  easily achievable, and a fun mental therapy day As for time to kill, I retired last Wednesday, so apart from my physical training, my days are filled with lots of random jobs around the house and garden...."Idle hands are the Devils something something" I am also buying a new house sooner rather than later, I'm actually looking at a potential property tomorrow, I'm looking forward to getting a car hoist as I'm starting to get to old to crawl around under a car, I can only imagine all the undercarriage cleaning and looking at stuff when that gets set up

      Yeah, I'm not interested in wetting the carpets, and I don't care about brown dirt/dust that lives deep in the pile or underneath. It's not like I crawl around on them in my birthday suit or eat dropped food off them (because there is never any open food in my car). The seats are alcantara (cheap Chinese imitation alcantara, to be sure!) with barely 1" of foam pad behind the surface. That's not getting wet either. Any car that I would be happy to get the interior wet, I would not care to put the effort into.
