Sandblaster!

[Naz]

I got my hands on a sandblaster unit. Love the results. Going to have all parts anodized before reassembly.

For aluminum parts like valve cover, water divider, intake manifolds, have them tumbled for an oem apoearance.  I also have them clear ceramic coated, you can wipe them off with a Kleenex!

I like the sound of ceramic coating. I may anodize all these parts blue then ceramic coat. Thanks

I'd be making sure those parts are cleaned and rinsed THOROUGHLY to get rid of sand.  I believe bead or walnut shell blasting is preferable to sand for "internal" engine parts.

Also be sure to really clean out the cavity under the breather nozzle on the valve cover and the dip stick tube.

Hans, I used glass beads on the aluminum and then tried walnut on the steel parts. Preferred the glass.

What Hans said.  I got a completely rebuilt 1600 head recently with all new components and a 300 cam.  The cylinder head bolt holes were still full of sanding media.  I plan on taking it completely apart, cleaning everything and rebuilding it.

So I don't think anodizing is a good idea. Because the parts are cast the results will be less than desirable. (According to shop) Looking into powder coating instead but not sure it can withstand the heat. May have to simply prime and paint these parts myself which I don't mind.

Well I found a shop not to far from me that is going to powder coat al those part blue for me. Pretty close to the BMW blue logo. I'll post pics once it's done.

I gave everything a few coats of Wurth Aluminium paint

[Naz]

Hans, that's a nice clean looking engine. I like it

Blue?  Please don't.

[Naz]

I knew you wouldn't like that chris. I'm still debating it. Trying to picture it. I may just powder coat it all a pewter colour. How about just blue hoses then?

Hi Naz

Doing some powder coating starting later this week.   I have a bunch of engine parts that I am doing for Paul Winterton's extra tii engine.  Also just got all the stuff to start doing both gold and silver blue/clear plating as well.

 

Give me a call, anytime after 6

 

Thanks, Rick

Why not hard anodize to the original silver color? Then the engine will always look much cleaner
