Now I get no pressure at all whilst turning over (Even with top plugs removed) and then takes a while to make pressure with engine running.
This happens if it has sat a week or two.
Once I have pressure, which reads good, I can start and stop all day with instant pressure but the problem at first start up seems to be getting worse.
Fitted a mechanical gauge today to confirm this and also found I have the "ball" valve.
It seems like the oil pump has lost it's prime and is struggling to suck it from the tank. Is this possible?
I plan on getting the "mushroom" valve kit and will purge the oil system with air pressure.
