[Vwdiesel] pump leak-by

[mark shepherd]

'H' try running a thicker oil (veggie even) for temp test of pump piston 
leakage.

Surely no chance of vortices in pump with solenoid turned off...
1) Doesnt pumps internal lift pump work all time.
2)If solenoid does also block return xs oil; Wouldnt pump reservoir just 
pressurise to a  level limited bythe vanes of the same and then just spin in 
the stationary fluid...vortices only created with starvation of supply?

Anyone have oppinions on the engine braking/ carb butterfly wear 
correlation?
