Before I went to Castlecombe my carwas making top pressure at 2000 revs.
Now after Combe its only making half pressure below about 4k,
At cold start I get 3 out of 4 bars but as soon as it warms up it drops back to 2 bars.
Is the pump dying or could it be something else ie releif spring?
I know lee may said his nova did the same thing but returned to normal after a couple of days, mine hasnt returned to normal.
I know the car is also due a service.
