Well I got my cylinder head back from the machine shop on friday, and
went to put in on top of the block, but never actually set it on the
block, just kinda hovered it over it.  Then decided I needed to do a
coupla things first, so I took the head away from the engine, and what
do I see??  The flapping head dumped some glass beads down my two of my
cylinders! I got most of them out with a rag with oil on it, but????

What precautions should I take, if any?  Everything is together so the
chances of any beads getting into bearings is small, but how small?
Should I take the head back to the machine shop and have them clean it
again?  Am I paranoid?  Do I need to take all the pistons back out, or
will that just double the chances of a bead getting on a bearing
surface?

I actually haven't plastigaged the rod bearings yet, so it wouldn't be
a HUGE hassle.....

it makes no difference, but this is on a 1990 240 dl wagon

thanks!
