Because the gearbox runs sat in oil (unless you dry sump before someone points that out) |

And because 4th is direct drive, therefore lovely and quiet once cruising.
In the 13's at last!.. Just |

Is it A-Series only? I think it should be... So when some joey comes on here about how his 16v turbo vauxhall is great compared to ours, he can be given the 'bird'... On 26th Oct, 2004 Tom Fenton said:
Yep I agree with TD........ |

My oil returns from my head through the drops, and hasn't made any difference to the noise. https://www.facebook.com/pages/Fusion-Fabri..._homepage_panel
