Hi guys. I need a second opinion on my GTR. When i start her and let idle to warm up, after about 5mins high pressure steam shoots from the engine bay. Its fkn lound like air from a compressor and i nearly shat my pants. So not to take chances i towed it to the workshop and let them suss what happen. The first few times they stared her up it happened again and then this recent start up nothing happened. They said the radiator did not need that much toping up maybe 1/2 liter and there was no obvious signs of coolant on the radiator etc. Apparently temp gauge was reading fine although the twin thermo fans went on. They need time to find out whats going on. But they stated that my oil pressure was way to high. The defi gauge was running almost to max. And when she reved the pressure increased and apparently its not meant to? Coz i run a JUN pump it has a adjustable vavle to prevent this. the oil pump needs to be taken off to inspect and adjust valve if needed. But aprrently this is trial and error as there is no info on jun pumps as to what adjustments equal pressure. Said it will be labour intensive as the sump needs to be taken off to acces the pump and the cradle, radiator, balancer needs to come off. It has thin run in oil for the bottom end which may effect oil pressure? I remember last time that the oil pressure was high at start up but came back down after she warmed up. Can i grab people opinions and advice as to whats happening?
