Having done three EAS valve blocks just this week I have noticed 2 major problem areas.
1) Orings within block hard and brittle, cause: age and heat (more so age)
2) Compressor strip down and rebuild all show signs of severe dust ingress, cause: bad filtration of OE filter
first I'll go into comp mod.
Add a totally new filtration system by removing useless OE filter with a inline petrol filter.
How, simply remove OE fiilter, match up a 90 degree fitting where OE filter went in and attach a short length of fuel hose
to just go under Compressor then simply add inline petrol filter, change every service as they cost peanuts.
Another area for concern is the short length of pipe from compressor to valve block, well as air gets compressed it heats
up, this heat is nicely absorbed by the valve block, mainly within the exspensive diaphragm area hence why this pieces of
rubber fail as they do so the solution would be to route piping elswhere of a certain length and then to return back to valve
block, this way the cooled down air wont be as damaging to certain rubbers.
Just a thought and I will certainly be doing it to mine once I get the heads back on and running again (time time time)
Any added tips from yourselves welcome
