I know this is a vain hope, but.. I'll ask anyway.
Would you all try and keep the chat to the subject of the thread?
Start a new thread about new subjects. There's no limit on the threads you can start.

Otherwise it all gets very confusing for people looking for information about one thing to end up in a discussion about a totally different subject.

Or for someone to find that vital piece of information about inlet manifolds when it's in a thread about brakes.
