It seems most rocker assemblies ( used ones ) have a lot of wear either on ths shaft or the rockers. I replace the shafts on all builds and rebush and hone the rockers. The latest type are throw aways. Once the valve tip wears into the rocker or it wears at the shaft bore they are done. Early cast/ forged ones can be bushed and the tips reprofiled but will require heat treatment. Pressed steel rockers can be bushed, reprofiled and heat treated. Try to buy a good quality shaft there are pure junk ones out there. Steve (CTR)

It could be blow by or not enough venting on the engine.
If in doubt, flat out. Colin Mc Rae MBE 1968-2007.

CTR, I'm using a K&N filter. Unfortunately, the elbow and airfitler box that would have originally been with the carb when I first acquired it are gone.

We don't use them in FL either so when i have an aftermarket manifold i cut the crancase breather hose and run it through the water jacket, just looks cleaner to me.

Yes. I removed the water pipes, they were rusty and I fgured I don't need a heated manifold.

That should work but couldn't you have tapped the existing hole where the freeze plug is and use a banjo fitting or 90 degree take off or is that a water jacket ?

Added a PCV valve whether it is needed or not. Since there is no boss I made a spacer for the spigot to bear against and support bracket. The back of the spacer is contoured slightly to conform to the runner. The casting is somewhat thin so I could tap only a few threads. It remains to be determined whether it leaks and I ruined a perfectly good manifold.

Can't you just feed it into the carb port ? It will be the other side of the butterfly but i don't see that it would make a big difference.

At the moment the crankcase vent vents to atmosphere through a K&N filter and there was a fair amount of oil film on the motor. I am doing a piston job and do not expect further problems BUT still I would rather send what fumes there are back into the motor. I was thinking the fumes might degrade the mixture in the 2 cyliders fed by the branch.

No it has been covered before CC, why would you need to ? Oil loss issues ?

I want to put a PCV valve on an single carb manifold. Obviously I'll have to put it on one branch of the manifold. Does anybody see anything wrong with doing this?
