high oil pressure

[racebreed]

my 56 vxr has started getting high oil pressure. runs 3bar on cold at idle and at lowish revs however if i run high revs up to the redline the oil pressure can go to 5 bar!!!

any suggestions?

Call Roger or Mark, might be your pressure relief valve.
Is your oil changed regularly?

its only done 15000 miles its had a services as it should

it has played better today only going to 3.5bar when booting it which seems normal

not sure if the valves getting stuck maybe?

ill get it to vauxhall if it continues
