Wingnut Mod started
----
Right I have started the wingnut mod finally. Cleaning the spare EGR valve I had bought a year ago.
I am amazed by how caked on the soot is and how messy the stuff is. I dread to think what the some of the components are like inside the car! So far I have tried oven cleaner, tar remover, degreaser, all purpose cleaner and fairy liquid. By far the best combination to break down the soot is Biological washing powder and boiling hot water. You still need to work it with a brush but it certainly makes things easier. Pictures will follow tomorrow.
For those who don't know what the wingnut mod is. It is basically a Stealth Race EGR Pipe that has been gutted, sealed and still which retains the anti-shudder valve.
