Strange top end rattle?
Discussion
I bet I can guess who said 'slipped liner'.. a Coventry company may be....
I tend to think it's slight piston slap / small ends....
nothing to worry about as at least 75% of the 500's do it... some from new... others can start afer as little as 15K miles... some at 75K still don't?
If you hear some other engines they can also sond like this.. the Ducati I once had was similar... but was fine... and ever listerned to a speed 6 unit...
No.. it will be fine.. get it sold!!

Probably not who you're thinking of I tend to think it's slight piston slap / small ends....

you're about 30 miles too far east. ellesmereFNC said:

Mmmmmm.. no idea in that neck of the woods.... I was suggested to me by 'you know who'... and I thought it a strange call?.... you're about 30 miles too far east. Does this 'other' places / person have evidance of this... and have they cured it by replacing the liners?
Yes tvrbeaver did. Its little ends. He put in new pistons n pins and all is well.
Tvr got to 5 litre by using a 90mm throw crank but then used an off the shelf piston from the 4.2 engine. Using this piston meant they had to make their own conrod which ultimately was too short and therefore has too much movement. It is thought that this excess movement of the rod is what brings on this little end wear. They perhaps would have been better using a much shorter piston and therefore longer rod of better dimensions. I suppose the way they did it using an off the shelf piston was the cheapest way.
Now why some do it and some dont is anyones guess.
