From the previous Idle videos i did, this is after i changed the exhaust manifold and the metal manifold gasket, i also did a little modification on the exhaust where the down pipe joins the Catalytic converter, basically i drilled the holes bigger from M8 to M10 as i had bigger stainless steel bolts that was more stronger and stops any exhaust leaks.
The manifold has had its bracket re-installed that normally cracks on these engines, and therefore the manifold looses its support, putting stress on the metal gasket and studs, i think this is why i had a manifold leak.
The idle is noticeably more quiet than the previous videos, but there is still a 'pinking' noise present, not as bad as it was.
