Howdy Folks,

I have a 68 Toro that I have been playing around with. I came across a 67 Toro air breather and thought it would be pretty cool on the 68.

I was doing some research trying to figure out if it could be done easily and fairly painless.

I found three different Toro air breathers. The one I have does not have a single hole in it at all. I took it off a 67.

If you look at the other two air breathers I found you can see that they are plumbed into the right valve cover, although in two different places.

I now find the breather I have a bit baffling!

Does anyone have any thoughts on this?

Cheers, Jim

 

The difference is in whether the car has open or closed PCV system.

An open system does not have an air pipe from the aircleaner housing to the valve cover or a crankcase filter inside the aircleaner. It uses a simple breather mounted in the valve cover with no connection to the aircleaner.

Closed systems use either: a filter in the aircleaner pan and a pipe to the valve cover to supply fresh air to the crankcase ventilation system; a fresh air pipe from the aircleaner pan to a valve cover mounted filter; or a fresh air pie from snorkel to valve cover mounted filter. Depends on year and options.

For a 68, I'd say you need a closed PCV aircleaner with air pipe routed from the aircleaner pan to the valve cover. 68 put the breather filter in the valve cover so you will not need a filter in the aircleaner pan

Be glad you're going for a dual snorkel instead of a Climatic Combustion Control unit. There are four different variations of those.

 

Gotcha! Thanks!

Jim
