Do you just work on engines that are sent to you ?

Or can you drop and reinstall the engine too ?

Thanks,

I do engine machine work, not setup to work on cars here.

I was wondering, what type of media do you use? I know that with certain types you can't use it because it will embed itself in the material and could possibly ruin the engine.

[fiatnutz]

I use a cast stainless steel shot that does not stick to dry parts.

How are you absolutely sure all the media is removed ?

You say the core plugs are removed, do you then just spend a long time blasting air throughout the block ?

Thanks

The plugs are removed and the block is washed in a pressure washer, then long boiler tube brushes are used to remove the media. JE...

This process does expose the aluminum to corrosion. It looks nice once it is done but after a while can corrode. Not good! Need to protect the surface with thin anodize not hard anodize after shot peening or preferably glass peening.

mag cases should be shuffle pinned...dowelled to each other so they don't fret

[vochitoken]

won´t this process harm the mating surfaces?

Cylinders fire independent, just like other "Boxer" engines with a firing order. Only one engine that I know of had simultaneous firing of two cylinders which were actually TWO flat six engines sandwiched together with both crankshafts geared to a separate main shaft output. It was on the Porsche 917 which held a world record for 238 MPH around a closed circuit. Mark Donahue used a 917-30 to set a record at Talledega Alabama that lasted 20 years.
