What is the best way to clean aa engine case
 

I am rebuilding an early 356 engine for a Friend and there is a Lot of corrosion on the case.

Is bead or walnut blasting OK or is there a better way.

Thanks Lorne M.

Walnut shells might be ok but soda blasting would be the safest way to go due to the ability to wash the soda away. I wouldn't be able to sleep well knowing there had been beads in or around the engine.

Also have to say I don't have much experience with the 356. Hopefully someone that has done it will chime in.

Send it to Ollies for ceramic tumble.

++++1 for that. The results are amazing.

Another satisfied custumer of Ollies here. I have the same case as pictured in the link and it is great.

Is the ceramic tumble just for aluminum cases or can it be done to magnesium cases?

I have it done to both types,....:)

Thanks Guys
