Safe to sandblast 550 head with cover and beather cover all bolted down?
« on: August 30, 2011, 01:07:30 PM »
I am about to sandlbast my head, valve cover, and breather cover.  I figured if I plug any holes, and put the side covers on the valve cover.  It should be pretty say to blast the whole unit.  Does this make sense? has anyone do it this way? or have a better way?

ive done it,masked up for about an hour first,then blew air followed by soapy water followed by air over a few times afterwards,undo the masking carefully watching for sand,not much fun but doable,not recommended for those with limited attention to detail.

It is ok, BUT spend a lot of time cleaning.   Then spend some more. Oil and sand, glass beads, etc make a hard to remove paste.  Not something to travel through your motor.

I glass beaded my fork lowers, taped them very well and still got beads inside.  Solvent, brushes, followed by hot soapy water, i finally got them clean.  Took more time then the bead blasting.  I like the way they look and I would do it again.

BTW, are the values out and how will you from protect the value guides and bearing surfaces?

Ditto what Steve K said..  i've done a lot of sandblasting and that stuff ends up everywhere no matter how good you think you have stuff covered... IMO I would get a good Dremel tool....some 22cal gun cleaning brushes...buffing dohickies and go to town..

Too late fellas, I am a gluton for punishment.  I did a ton of taping off with masking tape then duct tape. I should have mentioned that I was only blasting the outer part of the head etc.  I just wanted to make a good surface for paint to stick to.   The only spot that I was worried about was the exhaust ports,  since I will be pulling the valves out to lap them I'm not too concerned.  I plan on taking everything back apart and spraying it all down with solvent, I have to remove all the gasket residue now, which i really should have done before the blasting.  I did the blasting for appearance only so I made sure the business end of the head was taped off really well and it was sitting flat on a box so I doubt much media got into the oil galleries.  I also made sure to plug the cam chain tensioner hole with a body clip.  I will be interested to see if media made it into the ends of the valve cover where the two caps are bolts on.  I figures since there are O-Rings on those cap pieces nothing should get into the rocker shafts.  I guess only time will tell :)

Was going to suggest use baking soda or washing up powder, or soda crystals as your grit then it just dissolves and washes away when you are finished.

I used fine grit glass media.  It was great shooting at 70psi from about 4-6 inches away from the area you wanted to clean.  Best part is the small beach I created in the parking lot behind my shop.  I'm thinking I might bring in a beach chair and a cooler full of beers for lunch break.
