I'm hoping this is just a gauge or sender issue, BUT...
On startup, pressure gauge needle leaps across and LOCKS on the max stop. As engine
warms, it eventually drops, but will show high if revved. Tried various different oils, and thoroughly flushed engine
Fear suggests it might be the pressure relieve valve. That would involve an engine removal
. Very hard on my boat!!!!
Anyone in the UK know where I can get a mechanical gauge and connectors (1/8 npt??) to test it? Tried the normal Perkins
spares outlets, with no luck;-(
There's no more blue smoke than usual, which I'm hoping means the pressure is not 'real'.
