Hi Chaps, whilst talking about Valve Stem Seals, I thought that it would be a good idea to show owners my ”mod”.
I have also included a picture showing the Spring Clips that are fitted to prevent the Valve from dropping down into the Cylinder Bore in the event of a Valve Spring breaking.
If the Spring Clips are missing, they can easily be re-made by cutting the coils from a very small Spring .

I should add, that although the Seals are a “ Push fit” onto the Valve Guides, I secured them in position with a spot of Super Glue ,to ensure the did not lift if they came into contact with the Valve Springs . 😀

Next job, we’ll having refitted all of the Valves etc, I have discovered that the Core Pliug at the rear of the Head, has some very slight Rust marks around part of one edge, so it’s off to my local Engine overhaulers to pick up a couple of new Core Plugs, let’s hope all goes well with it’s replacement , will keep one as a spare !

Cheers Al :)

Hi Chaps, new Core Plug now fitted, so I turned my attention to another problem that has been bugging me for longer that I can remember.
Im not sure if any of you other owners has experienced the same problem, but I have noticed that the Head Gasket has a tendency to allow water to permeate along or through it ( not sure which) which then exits along the edge of the Head Gasket, anyway it’s always been an “Anoyance” , so I thought that while I Head was off, I would at least try and find an answer.
I had noticed that most of the Cooling System Ports in the Head were suffering from corrosion around the edges, so I have used this product ( pictured) to build up the corroded edges to hopefully help prevent these leakages.
The product in question is called Hysol 3475A & B produced by Loctite, this is a superb product that I have used with great success in the past on other applications, and it’s very “Tough” !!

Take a look at the rest of the pictures, this will show how the edges of the holes can be retrieved.

I have now repainted the Cyl Head and it looks great!

Cheers Al 😀😀😀
