Its a 3.5 on twin su's from a 89 Defender.
Which valve stem seals do I fit?
The ones that look like a flat washer seem a bit of a tight fit on the valve stem.
The smaller diameter but thicker ones seem a bit of a loose fit on the valve stem.
By the way for those of you that responded to my threads some weeks ago regarding trying to diagnose the noise this engine was making - a small piece of metal ie the curved part of the end of a spark plug was embedded in a piston crown!
Thanks
Gerald
