Ok, so thanks to D'Prived, I got some valve covers that I'm gonna powdercoat.

The guy told me I need to remove any interior baffles on the inside of the covers since when they get sandblasted, there might be some stray buildup behind them. Don't want that in the engine. I can't remove them. They're riveted in.


Now uh, why can't I just wash out the covers really well? He said he would have to "soda" blast them instead of sand blast to avoid that. Of course this is more expensive.

I figure I remove the gaskets/bolts and tell him not to worry about it, I'll clean them up. I can soak them and clean them up after powder coating to ensure no grit gets in my engine.

Any one see a problem with this?

if you dont take the right measures to properly clean them, then your not going to get the best results. Idk anything about soda blasting, but maybe you can take them up to a shop and have them clean the valves for you? not really sure, i always just sand blast my stuff.

Sorry, I mean cleaning them AFTER sandblasting.

I know they need to be cleaned and that really fine sand is hard to keep out of places.

Just not sure if it's a huge problem that I can't clean them myself.

I took a large piece of styrofoam and attached it to the bottom of valve cover to keep out the glass beads. Then I blasted the cover, took the styrofoam off, blew it off and then washed it in a parts wash tank with solvent real well. Hit it with compressed air and make sure it is squeaky clean. I then took it to the guy who did the powdercoat, and they turned out fine. No issues with the motor either. I bolted the foam to the cover right thru the holes that hold the cover on the motor.
