Wierd noise when i floor it, sounds like theres no exhaust, but there is, only whenyou floor it. The engine was low on oil so i hadto drive 1 mile with just below bottim nark and get oil, i hadto buy total quartz 15w40 performance. Or nothing else! Any ideas? Just sounda like no exhaust! |

Check that your air-filter cover is screwed on properly. |

Check over all of the exhaust joints - if you cup your hand around the joint, you'll feel a blow. It's well worth having a good look all over, too, first thing on a cold morning, since you might well see any exhaust gases. A trick I've used in the past is to dribble a little engine oil down the carb throat with the engine running. Again, it makes the exhaust very visible, so you'll see if the gases are escaping. It takes a little while to work fully, because the oil tends to sit in the inlet manifold for a bit. We did that to Jono's car at the French Nat'l this year - nothing visible at first, but we found and sorted the blow fairly quickly. Then, later, when they went into town... Smokescreen! |

if you had a backfire at some point in the latest round of calamity then check the heater tubes/balance pipe that run from the exhaust manifold stub to the carb also the cross box , spigots swan neck etc Sean |

If it;s just when you're flat out, then in my experience you're air filter is popping up. I've seen cars with threaded rod through the entire assembly to keep it down. |

It's worth looking at the swan neck, too. Ellie's car had a pinhole in the swan neck, where the clamp had chafed through. Quiet, until you hit the second choke. |
