As the car is laid up pending a return of the goodish weather my thoughts have turned to getting the inlet manifold off and cleaning the valves and inlet on my 2016 GDI.

I have found a company that does this and walnut blasts everything. Has anybody any experience of this and what were the results if any ?

I have yet to ascertain the cost but quite like the idea looking at the published results.

Thanks in anticipation
