TR6 Breather Question

I got a breather tank before my engine rebuild as before the rebuild, it was pushing oil out the top. Reason was number one piston was just pumping air and pushing it out. Anyway, I installed the tank and connected to the vent on the valve cover. It showed it had fluid in it so I emptied it. It seemed like mostly water, with brown globs of some oil. Is the water to be expected? It didn't have much oil in it so I know that's OK. I assume the water is because of the temps in the engine and it creates water vapor.

Is this an issue?

That emulsion can clogg up the plumbing, particularly in cold weather. The longer the connecting hoses going to and from the separator tank the more likely it'll happen.. If you notice your exhaust suddenly look smoky or if you notice oil accumulating at the seam where the cylinder head meets the engine block above the spark plug side of the engine, you probably have emulsion clogged hoses.
If it sounds like I may have experienced such things, you'd be right.

Poolboy, thanks. I did notice, before I emptied it, that I had a puff of smoke on start up. I was concerned that my guides didn't get replaced on engine build. But it disappeared since. I'll have to keep an eye on it. The line from the vent on the valve cover to the canister is a bit long as I mounted the canister on the radiator support. Do you have any sort of filter on the exhaust side of the canister? Not pushing any oil out anywhere, thank god.

I got rid of it. I know it was a long post that I linked to, but read thru it and you'll see that was the ultimate solution. It's not needed.
In fact my engine plumbing is a lot simpler nowadays
 
That looks nice and clean. Unfortunately, I am running SU's and they don't have a port. I could run it into the air cleaner though. I'll have to take a look.

Thanks, Perry
There is that other method that's illustrated in the link I posted..the method using the PCV valve kit from Richard Good.
