Yeah and said everything looked ok, seems to be more the HR engines with those issues, was reading back over a few threads and seems quite a few are saying the 15/20 Psi mark is ok,
One guy said Nissan say above 14 PSI is ok but I'm not sure how you relate that to be a issue, if it could run at 15 and be fine for years that's fine but if it gradually gets lower its not looking good (again)
