:confused: Having stripped down my old EAS valve block yesterday I discovered what appears to be yellow marker paint in two of the non-return valve recess's which would presumably have effected their operation, anyone any ideas why this might have been done?
 
i dont understand where it is, but could it be any form of grease?

maybe its something thats melted in there or could it have got in somewhere?
 
Could be! question is why...... this was a working valve block when it came in the car, I've only swapped it out to refurb it, after problems that appear to have been mainly compressor related. Why gunge up one valve with anything at all??? It wasn't as if it was somewhere it could have seeped from a thread, it must have been done deliberately.
