The car isn't really in a local area, it's about 400km return. When I return l'll be doing a more in depth look, will do a compression test inspect the heck out of everything. In the cars defence, it was parked in an open sidded shed, out on a farm over a year ago. There is wasp nests and mouse/rat crap everywhere and urine scented interior. The video was taken after the car had been started for approximatly 5 mins. This is the first time it was started since parked in the car. I have heard from a few sources that due to it sitting so long the lifters could dry out which could have been the noise. Unfortunately after the test drive I didn't pay attention to whether the noise was still there, (shake head). Unsure at the moment of the cars history, the owner and knowledge of the vehicle wasn't there at the time, it was only his son, (there's the car, over in the shed) knew it was a gtr and black? That was really all.
