I'm trying to find out where to get hold of the stronger spring for the CVH oil pump to hold the pressure a bit higher at idle.
Did the search on here and found a few old threads saying you can get them from Burton Power but I've just talked to them and they no longer sell the spring separately.

Bit of a weird one, oil pressure is low on idle after its hot, gauge reads about 5-8 psi. Plenty of pressure at anything above idle.

The cars been sat for about a year probably, the bottom end only has a few K on it after a full rebuild, and it was OK before being laid up.

It's had a total re-loom and I was out doing some base mapping. The pressure is fine when cold, and even when hot it jumps up when I touch the pedal.

It's a Ford pump bought at ridiculous cost when the bottom end was built.

Things I'm doing tomorrow:
Trying a mechanical pressure gauge (current is electronic and could be affected by the new loom)
New filter, new oil
Pondering if to mess about with the pump relief spring.

Thoughts?
