Dye dm10 air leak

[jason kitts]

Hi any one could help me my dye has a leak I've changed all o rings on the bolt and the lpr.
The lpr screw is all the way in as soon as I start to back the screw out it leaks its coming from under the solenoid I've all so removed the solenoid and greased the gasket as it states In the manual.
Any idea what this could be cheers

What does the reg seat on the lpr piston look like.
Have you taken out the entire lpr assembly, I've seen them not seat properly.
