Valve stem seals Le Mans

For now, I lumped all the pre-war cars together, I would LOVE for there to be enough demand to split it into groups (hint...hint, post here about your pre-war Singer)

I'm sorry Trev but I have no idea. You might get more knowledgeable responses from the SOC Facebook page which is a bit livelier than the Forum.

Why would you want to? If you are burning oil and are convinced it's through the valve guides the best solution is to fit new guides. Before you do that make sure you are not pumping too much oil into the rocker cover. There is a restriction in the oil feed pipe in one of the unions. It comprises a solder plug with a small hole drilled in it located in one of the union bolts. I can't remember if it is at the one at the front of the engine or the one near the middle of the camshaft. Also, don't set the oil pressure relief valve too high. A pressure of 30 -40 psi whilst motoring is fine. If you look into the filler cap when the engine is running you should see a dribble of oil rather than a flood and a pool of oil just deep enough for the lobes of the cams to dip into.
