I have decided to split the case on my original 914-6 engine and would like some advice on how to get a proper finish on the case. I want it to look like it did when it left the factory.
Is there something I can use or a process I can follow that will bring the engine case to an original finish ? Or do I just send everything to Ollie's and let them do their thing? Any information would be appreciated . Attached thumbnail(s) |

It looks clean of crud, so find a shop with a large tumbler ( steel shot, plastic bead etc ) that will run the case in it. Most of the places that do ceramic coating will have one as that makes the "chrome" ceramic look shinier. You don't want it chrome looking, but a nice even al. finish. You just need to polish off the growth and get a smooth finish

If you're really looking for 'from the factory', polishing of any sort won't do it. Media blasting will get close if you use a SUPER soft grit and a lot of time (fine soda). Dipping of some sort might be the best option, but you would need to find someone who knows exactly what they're doing because serious case damage could occur if you're not careful. But dipping would give you the most even finish.
Basically you're looking for an even texture across the whole part. Polishing won't get into the nooks and crannies, and you either leave sanding scratches or polish to a mirror finish. Neither of those are technically correct. The case on the left was soda blasted. Attached image(s) |

Any information would be appreciated . I think you should talk with Henry at Supertech. He knows how to do it all from mild to wild, budget or perfect resto.

Your case is magnesium.
Halibrand and (real) Minilite wheels were magnesium and were treated with a preservative wash. I cannot remember the name right now but it was a Dow product. I'll bet the product Glenn suggested is the German version. Do not blast with anything other than solvents or hot water. Ask the Porsche concours restoration experts on Pelican, someone there should know. |

Gibbs spray lube the case after it's clean. This stuff soaks in and give a beautiful finish and brings out the marbling in the magnesium.

Thank you for all the advice everyone .
I thought about sending everything to Ollie's Machine shop as they do a media tumble but it sounds like that is not the way to go. I have had that process done on a few of my 935 cases but they are aluminum and I have no point of reference on a mag case so glad I asked |

I had Ollie's tumble the case on my 2.7 and it came out great. Smooth, not shiny.

Henkel Alodine 598970 Magnesium Treatment Glenn Any suggestion as to where to buy the kit from? My search came back with limited results. VZ935 A long time ago when I restored my 914 I used a company in Indianapolis IN that was doing engine & transmissions castings restoration for the 356 guys to clean and bring the finish like it came out of the casting mold. I just can't remember the process or name but check with the 356 guys for advice or suggestions. I was happy with the results and my engn & trans still look factory fresh. The only thing I remember it was some kind of dipping process to a fresh factory finish. Ask the 356 guys. Tom Attached image(s) |
