Hi all,
A year or so ago I replaced my exhaust manifold with the japanifold, and swapped my turbo core because I thought it may have been causing my oil smoke (it wasn't). The manifold has no visible cracks, and whilst the core is likely fine it has also been sitting on my garage floor not getting much attention since I swapped it.
If anyone is interested they are free for pick up from Newcastle. May post in a few weeks if no one has picked these up, but sorta can't be bothered packing and sending at the moment.
