So i just got my valve cover back from being sand blasted at a powder coating shop. And when i got it back a shitload of sand fell out when i picked it up! I dont think the shop masked off any of the holes on the cover! Should i just wash it out with water, put it in my dishwasher, use an air compressor and blow it out, use a solvent to get off the grime which the sand sticks to or am i screwed and I should just buy a new one? Any advice???

 

I would try and compressor water through it for a while

 

yea like a pressure washer?

just blow it out with an air hose, or throw it on a parts washer

 

Pressure wash then blow out with 100psi.

 

Blow it out with air first. The water will only make the media stick to the insides of the cover. Since the baffles on MOST honda covers are rivetted, you need to be VERY careful. After you pushed through some decent air THEN give it a good rinse with a hose, tilting the cover to allow for water to flow everywhere and move the media around and out of the cover.

This is pretty bad IMO. Be VERY careful.

thats how every cover iv ever goten done comes back, just drill the rivets out, remove, baffel, then rivet or drill and tap the wholes and bolt it back in

 

problem solved. i just cleaned it ALOT with brakecleaner, soap, water hose and air blasted it. i also used a wire brush to get into creases. Hope this helps people out.

 

That's awful. Your blaster needs to mask/plug them or you should prior to sending them out. It's gotta be less work to mask than it is to drill/re-tap.
