Does anyone have the specifications for the oil inlet valve spring for early 2 3/4 engines - Part number 424.   I have tried to order one from the club spares but apparently Jeff Swan is indisposed at the moment.

Have you tried the new Drafts feature yet? I just lost a long message today and learned my lesson. It is a good idea to save a draft of any long post you are writing. You can then just keep writing and keep saving a draft, knowing you have a backup if there is a glitch. The draft is automatically deleted when you post the message.

Hi All
Can any one help me with information about head gaskets the copper O ring for DT or overhead valve models?
Is there an alternative or a suppler of these large O rings as per war spares do not hold this item yet?.

Ian

I would certainly be interested if you find a supply - we just used flat copper.

Kevin,

There is a discussion on manufacturing DT head joint rings in this post.
