Does anyone here in the New England area (NH preferably) know of or recommend a specialty shop that works on minis? In the future id like to walnut blast the intake tract and other preventative maintenance things. Just trying to find a shop that's familiar with that sort of stuff and knows the platform. TIA

 

The intake is plastic. Wouldn't walnut blasting shred the plastic? Is there something I am missing?

 

That's why walnut blasting is recommended, is way less abrasive and it cleans up the caked on oil.

 

The blasting is done on the back of the intake valves, not the intake manifold. The intake manifold is removed for the process.

 

Thank you for the correction as I meant to say intake valves haha.
