Hi all, I have been slowly putting my engine back together. I went to clean up my coolant piping and found a few little issues. Here is the piping I am talking about. (https://imageshack.com/i/1xkghoj) First up does this part look correct? (https://imageshack.com/i/giw653j) Just by looking at it i can tell it has been modified. I tried running water through and the thin pipe doesn't allow any water to go through. I'm thinking where that pipe is welded on it has either rusted shut or never was open. Which makes the next issue make a little more sense. The pipe that connects to the pipe with the issue has a small hole in it. (https://imageshack.com/i/nae2rpj) When i had the car running, which wasn't for very long, i never had any coolant leaks. It was only once i gave this pipe a light wipe that the hole was noticeable. Could this mean that i didn't have any coolant running through this hose? sure it would have had some at some stage for it to rust but i'm thinking that whenever the previous pipe was modified the little pipe never had coolant after that. I would just try to get second hand parts to replace them but since im in NZ ill have to fix these or make new ones. Some original photos have not been recovered yet.

There has to be other rb30s you can get pipes off in NZ mate. I live remote in WA and I still get every thing I need from across Australia. By pass the plenum if your still running the stock gear. T pease the coolant bypass. Other wise those pipes are to stay as nature intended for best results. You won't see them plus the amount of crap that runs under the plenum will make it a fruitless exercise. Good luck in finding the pipes mate.
