Hello everyone! Here's a p

Hello everyone! Here's a puzzler for you:

365BB

A loud, metallic knocking sound with vibration coming from behind the seats under hard acceleration in the lower gears, whether in a straight line or around corners of either direction.

My mechanical knowledge/ability is limited to say the least. Nevertheless, I made my initial diagnosis with the help of some chaps on another site. We'd got the wrong end of the stick, as it turned out...Could anyone (other than Simon!) say what the matter was? I'll post the answer tomorrow night (GMT).

Sorry, no prizes; but just imagine the kudos

Hi Thomas and welcome aboard.

These contests/quizes are fun, thanks for posting this challenge.

I can think of at least a half dozen things that could cause such a noise, and even then I feel my chances of guessing right are remote. Not really enough info for me to make anything more than a wild guess, so definately Kudos to anyone that could stab in the dark correctly.

However stabbing in the dark...loose wheel.

We do have 2 other 365BB owners here though, David & Simon, maybe they've even had the same thing happen?

Regards, JRV

I'll bite.

Water pump impeller hitting the housing...
OR, loose crank pulley hitting the alu water tube...

Best I can do on the information given...

How about this: Something caught in the gear shift lever to cause the engine to engage, and disengage?

Hi...........

The alternator and its drive belt sit behind the driver, in close proximity to one of the gasoline/petrol tanks. Perhaps the alternator bracket is loose or the alternator retainer bolts have fallen off.

Does it do it in the garage or only at speed ??

The thick rubber washer holdin

The thick rubber washer holding one of the exhaust boxes in place had split, allowing the exhaust repeatedly to whack itself into the housing. A relief, I can tell you.

Thanks for your answers everyone. Inventive when you had so little to go on.

Frank, your top site made for some rather exciting reading when I was making the decision to buy. You're a star!

JRV, thanks for the welcome. You may remember me from a little contretemps we had about guns and locking front doors a while back

This site to me is a fascinating challenge. I'm trying hard to follow some very serious and detailed discussion about how my car works. Already this is another established and very valuable resource. Bravo!

????????can't say I recall?????????????????

Last Bar Brawl I don't remember but was told about later was in the Phillipines - 1971...US Marines vs Royal Marines...we won of course...(

Have to admit you had me stumped on this one...I don't think I would have gotten it even with a dozen tries...{

See, I knew that. I must say that the reason I knew that is 'cause I saw the question answered in the UK and I must admit I didn't guess the answer either. I did, however, know that it wasn't due to the need for a new gearbox, which is is what most of the 'experts' over here were saying.
