Hi folks,
I am about to have new guides fitted to my 1935 model 18 head with naked valve springs.
I can't work out or find information on how these are lubricated.
my 16h had nipples on the side of the valve guides but I can see none on the 18 head.
there are two threaded holes on both inlet and exhaust sided of the castings leading to the valve guides, but no hole in the guide walls to allow grease or oils to pass.
These holes were blanked off with grub screws which i have removed.
Any advise appreciated

The contemporary Inters are…
The contemporary Inters are of course well lubricated (over lubricated?). They have holes drilled in the sides of the valve guides to line up with holes in the cylinder head for oil lubrication feed tubes. It sounds like PO didn't drill the grease lubrication holes!
Page 6 of the maintenance manual describes grease nipples on the bosses holding the valve guides. https://drive.google.com/file/d/1s0fnaCPwa1IiKhvy-QRMz62UPPsA7TrG/view
PO of my Inter had a 1920's vintage sports/tourer car with open valve gear and started every run with a squirt from an oil can with a moly disulphide oil. Made a horrible mess...

Do you know what the guide material is ?. For the time being ,if guides cast iron you could carry an oil can and lubricate the guides before riding and every few hundred miles. Messy but needed. At the Next SNOC (Surrey) branch meeting there will be a talk and film about the refurbishment of an early M18 and information about research into suitable materials for guides in early engines.
