Thanks John.
Correct S3 one now fitted. basically the same, where the TRE sits, Better drain angle on the dampener now. Horizontal before.

Put motor in, and added oil filter and 'New' Zenith.
I have been looking on line for a PCV valve. Don't seem easy to find, if so, very expensive.
What alternative set up do S3 daily driver use ????
Can the filler tube, rocker cover breather, just be joined, then into Steel Carby inlet Tube ???? Or does that create problems.
Or does anyone have a SH one, think new rubbers still available.
Thanks

Someone looks like they are way out in front of Homestar...

The reason they are hard to find is that since the diaphragm is the only thing to go wrong, they are rarely needed. But you should be able to get one second hand from someone who wrecks Series Landrovers, for example, Ho Hars on this forum, or possibly All four x 4 in Newcastle or Land Vehicle Spares in Silverdale. But they won't have them listed on line, you will have to call.

You can't just connect everything up as you suggest. The connection at the inlet has a high vacuum when the throttle is closed, and the engine running, and the PCV valve shuts it off in these conditions. Connected as you suggest would be equivalent to a bad air leak into the manifold, and you would probably have issues even starting the engine. If you did get it started the mixture would vary all over the place depending on how much blowby there was on the rings and what the engine speed was at the time.

A viable, but not good, temporary alternative would be to block the carby connection, and leave the other pipes open. This allows crankcase ventilation to some extent, but expect to see some oil drops coming out, and it will allow dust into the engine, but the crankcase ventilation will still not be adequate. And the mixture will not be ideal, as the jetting assumes some air coming in via the PCV at large throttle openings.

Other alternatives would be to try a local auto supplier for a PCV valve off another make that can be adapted, or to convert to the pre-emissions setup with a gauze filter on both the top of the rocker cover and the oil filler.

And you should realise that anything except the standard setup will be illegal, although very unlikely to be ever picked up.

Look under Mini, MGB& Triumph most of the Leyland range of vehicles used the same PCV valve. I fitted a Holden valve on my MGBGT because the origional diaphgram one was giving me trouble it worked well. I eventually worked out that the restricter was missing out of the hose between the motor & valve . I made a restricter & fitted it & refitted the origional valve & no more problem. On one of my other vehicles I fitted a catch can with a filter on the top without a PCV valve valve because the PCV valve was missing but fumes were coming into the cabin so ran breather hose to rear of vehicle with the filter on end & no more fumes.

It is important to understand too, that Positive Crankcase Ventilation extends the life of the oil and engine remarkably.

Having a standpipe or a hose will work, but only when the vehicle is moving; idling in traffic, or running a PTO whilst stationary, will not vent any crankcase fumes or water vapour very well at all,

Hi John.
Land Vehicle spares, have sold up.
Stock bought by another group.
Will post details.

Hi,
Got rear diff rebuilt. had to use 40 thou shims. 50's had a tight spot.
2 thou run out on crown wheel. 8 thou on the pinion back lash, as per my manual.
New carrier bearings old ones bit rumbly. Bought small, 6 tonne shop press, and bearing removal kit ($30 ebay ) Makes life easier.
Got some paint on Radiator Panel.
Looked at gearbox. Understanding it better. Even worked out where the brass particles have come from. Should end up with one good one from the two. Shame the better one was left out in the elements.
Pics to follow, when I get a moment.
Found old horn on farm, scrap pile. Quick blow and clean, paint. All works, vey loud. Lucas No 9 I think.
