R32 GTR So recently my oil temp has started being funny slowly rising when on the freewsy sitting on about 3000rpm but if im cruising along doing 2000rpm or sitting at idle the temp slowly comes back down. Engine had a full rebuild only just over 5000km ago. I've changed oil filter and oil, thermostat, flushed radiator and have bled the cooling system but hasnt changed anything. Ive let my car idle in my garage for 45minutes and all it did was get to the normal temps then stay there. I wouldn't think my HG would be the problem as its all still new without having any thrashing. Nitto oil pump and a genuine nissan water pump were put on when built. It was 2 years ago the engine was built and i cant exactly remember but i think they told me i would need to come back in at 5000km to have the head re tentioned down. Does this sound right with arp head studs? If so this could be my problem?. Cheers for any input.
