[Vwdiesel] weepy injector

[rOLf peCHUkas]

hey all
my #4 injector has begun weeping
('93 EuroVan N/A diesel - 5 cyl)
this may or may not be related to increased backpressures in my  
return system
due to custom routing of return line(s)
Q:
what might fail in a VW injector?
before I tear into and rebuild the little bugger, any suggestions on  
where to look?
anyone know what's vulnerable to (back) pressure (through inj return  
ports) in there?
leak seems to be from around the injector returns (new lines) and  
possibly the IP line junction and injector body seam
thanks for any thoughts
