Hi, I've stripped out the pressure relief valve to find a grub screw (see photo) - between the spring and outer retaining screw. Is this an attempt to modify the relief valve to create higher pressure or is this a standard fitment?
Thanks for your quick reply - Not withstanding the various comments that appear on TVR from time to time I thought this seemed a little strange...........
Just ordered a new uprated one from Rimmer Brothers - I'm not keen on the grub screw set up. Fingers crossed this, the new oil pump gears and new main/big end bearings will improve the oil pressure situation.....
