SIDI Intake Valve Cleaning?

[Blackout]

The only way you will clean ALL of it is with walnut blasting or physically removing it by hand if you can reach. The flushes/sprays/hydrogen blasting is good if you don't have super high km's.

No, 174,???kms.
I might contact some cocks over here in WA that walnut blast german cars. They'd be so up themselves, they probably wouldn't bother.
