Rust inside intercooler pipes

[bamboo rocket]

Firstly I am newbie when it comes to engine work – but I decided to try myself to change the silicone hoses on my intercooler and paint the pipes.

 

I have now disassemble all the pipes – and all the pipes looks like in the first picture (a bit oily inside) – but inside one pipe it looked like it is rusty

(the pipe was mounted right after the intercooler on the passenger side - see pic)

 

Should I be worried – and how shall I clean it – make it good again?

 

It is a ARC intercooler with original pips.

Either live with it, get alloy pipes, or have the steel ones bright zinc plated.

you can clean it up with some wire wool if you want

Cotton buds dipped in Brasso, please. These Danes are a patient people.

just rinse it with some rust converter then clean up with wire wool so no loose bits will fly into your engine and spray the inside of the pipe with some fish oil or similiar rust inhibitor that will prevent it happening again.

I used whats called a flap wheel to do mine, i made an extension to fit to the shank though as that wont be long enough.

 

They come in differant diameters and grades of coarseness.
