ES2 valve springs

Forums

Hi guys

Does anyone know the fitted length of the valve springs on a late ES2 (58-62) I seem to have a weak exhaust spring but the valve seat doesn't seem too recessed.

I have the free length from Garratts book.

Cheers

Paul

Hi Paul,

hopefully the following is of some help.

I was trading emails with Mike Pemberton on my 1960 ES2 recently. Valve stem protrusion should be 48mm on new seats, no more than 50mm as the seats wear. If you have the collets etc you could then work out what the fitted length will be?

best of luck

iain.
