View Full Version : Another Catch Can?

Using this diagram, to keep the oil out of the air box, is it as simple to run #2tank to airbox hose to a resivor?

Yes, but make sure you block off the hole to the airbox. And that your catch bottle has a breather in it too. ie another hose running from it to atmosphere.

I'm not sure that's 100% correct. Lines "4" and "A" both vent fluid into the airbox from time to time, as the paper diagram suggests.

Line 4 for is not a vent, it is a drain that returns the oil accumulated by sub-compartment 3 back down to the crankcase.

Your idea of a second catch can is already in the stock airbox, but better. I doesn't need to be emptied and returns the oil automatically.

ahh.. I really dont understand Cals mods(Im a right brainer), all I get from the searches is to look at his pictures. Think you can tell me where the Cals re routes are on the diagram ie: #2 to resivor, #1 to ____, A to _____.

Aaahhh....just put a catch can on each line and plug corresponding points. After you see what accumulates in each catch cam you will have better idea of what each line is doing and eventually will end up with Cals system or similar, I'm using modified rotary breather on rear cam cover and it works, but doesn't eliminate water vapours from the system. U can use VDB set-up with all breathers running to the original belly expansion bottle and make a separate coller bottle for rads

Is it ok to block off #4?
