Hi fellow mini owners. I have bought the tools to do some walnut blasting on my N14 JCW. I'll let you know how it goes. Let me know if you are interesting in having this done!

 

Here is an example of one set of valves after cleaning

 

Well done. Kudos to you for getting the tools to DIY rather than paying $500 odd to a shop. How long did it take you to do a set of valves?
Keen to see how its done and what difference it makes afterwards.

 

Hi, sorry I never replied!
So funny story...
It made a difference for sure to how smooth the car ran overall. Only problem is that after i did the walnut blast, i went to the track and did a track day. then the car dropped a cylinder and basically blew itself up :(
That was the end of my MINI R56 era....
2020 was looking like an awesome year business-wise so I thought I would go and get a new MINI Clubman! Yay!
The COVID hit... :(

If i ever get an R56 JCW again, and I miss it so I probably will, then at least I still have the tools to do this
