Ya, I dropped the car at the mechanic yesterday to get a used motor installed. Newer motor has a stamp on the side indicating it was re manufactured by Nissan in 2007,has approx 60,000km on the rebuild.
I told the mechanic to loctite the butterfly screws & I got a catless header for it.
Fingers crossed.
